What we like in GD-100*comments by experts with 10 years experience in writing about Casio watches— 200-meter water resistance(good for swimming but not for deep diving)

Official Casio Description.Based on the successful analog/digtial GA100 X-large G series, G-Shock introduces an all digital version line-up. Black resin band digital watch with black face. Over-sized buttons come with a checkered anti-slip surface to make operations fast and sure. All of this plus high shock resistance and water resistance makes these G-SHOCK models the perfect choice for casual wear just about everywhere.

*some images are about G-Shock 5000/5600 cases, but the technology, approaches, concepts and philosophy remains the same for the whole G-Shock Model Range

Hollow case structure. Based on a realization that “shocks are not transmitted inside a bouncing rubber ball,” the structure was designed to let the module float inside the case, relieving shocks transmitted from outside. Today, the module’s shock resistance is realized through further technical innovations. But the revolutionary tough structure that gave G-SHOCK its origin began here.

All-directional covering. If the watch is dropped, the protruding bezel fully enclosing it absorbs the shock, protecting the buttons directly connected to the module and alleviating shocks from all directions. The bezel also guards the surface of the crystal. The band is curved stiffly at the point of connection with the case, moreover, enabling it to serve as a shock absorber and prevent direct shocks to the back of the case.

Protective cushioning of key parts. The crystal oscillator and other critical parts inside the module are guarded individually by cushioning material. Any strong shock to the watch causes immediate distortion of the cushioning inside the module, preventing contact failure and malfunction.

Japan Quality. Constructed with genuine quality, CASIO products provide truly practicable applications in which functionality and beauty combine. The leading-edge LSI technologies and skilled craftsmanship that give life to CASIO watches exemplify the quality Japan boasts in the world marketplace.

For CASIO, “faith in manufacturing” refers to an inexorable advancement of digital technologies and an uncompromising commitment to fine craftsmanship. This faith engenders unparalleled performance that not only elevates CASIO watches as close as possible to perfection, but that actually changes their wearers’ lifestyles.

Shanghai, as one of the top trendsetting cities, has not only witnessed the birth and innovation of various trendy cultures but also continues to forge diversified trendy lifestyles with a harmonious attitude. Shanghai’s nightlife is one of a kind amongst Asia, there are always unexpected surprises of East meets West. You can be easily amazed by traveling through the young and fashionable districts or be inspired by the trendy music bars lined around the corners. Shanghai nightlife is full of excitement.

With the theme of "Shanghai Night", G-SHOCK and BE@RBRICK launched a new limited-edition co-branded watch and doll series, which perfectly blends the modern romance of the bustling night of Shanghai with the thriving street propositions. This collaboration injects a new trend of fashion tension, custom-made for the new generation of night-walkers.

The G-Shock BE@RBRICK co-branded "Shanghai Night" themed limited watch is based on the classic metal covered series GM-5600 and GM-110, inspired by the radiant night view of Shanghai, using electric blue, glacier gold, and eye-catching rose-pink as the main design elements. Cool gradient color craftsmanship is superimposed on the hardcore metal material. The shockproof and waterproof function is still the same, and the toughness can be closely integrated with the dazzling color. Both the GM-5600SN-1 and GM-110SN-2 are dazzling and eye-catching, the neon metal shins strikingly on your wrist. The GM-110SN-2A has a blue IP stainless steel bezel and red accents. The GM-5600SN-1 has a rainbow IP stainless steel bezel with gradations of red, gold, and blue. Each watch has a black resin band and an inverted LCD display.

It is worth noting that the packaging box of the G-SHOCK|BE@RBRICK joint project is a set of containers, which represents that BE@RBRICK came to Shanghai through containers and then transport to various trendy places in Shanghai. The outer packaging not only outlines the city map with atmospheric black and white but also carefully marks the latitude and longitude of Shanghai on the surface of the box. The details further enhance the toughness attitude of Casio G-Shock.

G-SHOCK and BE@RBRICK are not working together for the first time, but it is very rare to have a city-specific imprint on the joint products of both parties. This time, G-SHOCK will follow the fashion context of "Shanghai", a city that never sleeps, creating cool night gear for hipsters, wearing them casually, highlighting the unique wrist fashion. With unstoppable energy, G-SHOCK will work with you to the dark night trend and travel in the mysterious bright night of Shanghai!

The DW-5000C is the original G-Shock model from 1983. The GMW-B5000 Series has inherited its characteristic square design and been given the full metal treatment along with upgraded features including smartphone linking.

The watch has been given a full-metal case by using a shock-resistant fine resin cushioning material inserted between the case and the sturdy stainless steel metal bezel. High-density mounting technology also allows the watch to maintain its size. The back of the watch features a solid Screw Lock Back and has been DLC treated for resistance to wear. The metal band has been dimple processed, inheriting the Resin Band design of the original. Visibility too has been enhanced via use of a film solar cell and STN-LCD (liquid crystal).

Function-wise, this model comes with Bluetooth® communications and can link with a dedicated app to obtain precise time information. The watch is also packed with practical features including a time correction system that uses standard time and frequency signals (Multi-Band 6), a reliable source of power in the form of Tough Solar technology, high-luminance Full Auto LED backlighting, World Time and day of the week display in six languages.

The G-SHOCK GBX-100 watch wasn’t high on my “must have” list. G-SHOCK touts the model as a watch for fitness buffs and surfers. Since I’m neither a step-counter nor a wave-rider, I figured it wasn’t a watch for me.  After its release in May 2020, the latest in Casio’s “G-Lide” series sold out quickly, garnering nearly unanimous praise on the watch forums. When availability trickled back I decided to see what the commotion was about . . .

The first thing that jumps out: the Casio’s “MIP” display. Whereas a normal LCD depends entirely on a backlight and pixels (that refresh themselves every minute or so), a Memory In Pixel display includes an optical layer that reflects and transmits light to brighten the screen.

In bright light, it’s perfectly legible. In low light, it’s perfectly legible. The GBX-100’s transflective layer (transmissive + reflective) allows illumination from a backlight to light up the display.

How much better is MIP than its Casio competition? Check out the above comparo of Casio’s negative LCD displays. Left to right: STN (Super-Twisted Nematic), MIP (Memory In Pixel) and traditional LCD.

In fact, the watch is so packed with functions, modes and information, I haven’t been able to delve into all of them, even after a full week of wear. Let’s hit the highlights . . .

The main time mode screen is easier to read than Bathtime for Biscuit. The date (month/day) appears in a smaller font in the upper right corner, large enough to read with my unaided 56-year-old eyes.

The day of the week lives in the lower left corner, projected in the same font size as the date. The activation status of various functions (DST, BlueTooth, Alarm, Signal, etc) appear in very small fonts along the bottom of the screen and in the upper left corner.

The Tide and Moon Phase calculator is presented in three different display modes. The Tide calculator is available in a 12-hour or a 24-hour graph format. The tide display includes the moon phase and sunrise/sunset times in a smaller font. There’s also a dedicated moon phase display that includes sunrise and sunset times.

From what I can tell (comparing to the NOAA website), the high and low tide calculations were off by about 30 minutes in my area. (I didn’t have time to sit on the beach to see for myself.) Compared to what I can see in the night sky, the moon phase appears to be spot-on.

The watch syncs with the “G-Shock Move” phone app. You can set up alerts for fitness goals met. Notably absent on the GBX-100: a heart rate monitor. That’s a deal killer for those hardy souls who sacrifice sweat on the altar of CrossFit.

From what I’ve gathered from watch forum chatter, none of the Casio step-counters are accurate. Word on the street: if you’re serious about using a fitness calculator on your wrist, get a “real” wearable like the models offered by Garmin.

The G-SHOCK GBX-100 Bluetooths to your phone. Activate the notification function and the watch will beep and vibrate whenever your phone wants your attention (text, email, phone call, calendar alerts, etc.). The Casio keeps up to 10 notifications before the old ones roll off.

It’s a smartwatch Jim, but not as we know it. To read a text from my son required six button pushes. No matter how many times I pressed the buttons I couldn’t reply. After half a day of being more connected to my phone than I wanted to be, I turned off the notifications.

The G-SHOCK GBX-100 is packed with features I’ll never use. Then again, maybe my new Casio will compel me to get off my butt to use the fitness functions. Or  hit the beach and “hang ten.” Or go fishing – where I’ll find meaning in the tide and moon phase and perhaps even life itself.

Time Functions:Digital hour / minute / seconds, date, day, stopwatch (1-sec), countdown timer, Four daily alarms with snooze, 12 / 24 hour format, World Time (29 time zones / 38 cities), hourly time signal, auto-light.

Display of distance, speed, pace, and other calculated values based on accelerometer, auto/manual lap times, Auto Pause, target alert setting (time, calories burned) on/off, training display customization (elapsed time, distance, pace, lap time, lap distance, lap pace, average pace, speed, average speed, calories burned).

Design * * *While a completely new model, the GBX-100 is a typical and recognizable G-SHOCK design. The shiny forged steel  bezel adds a bit of panache.

Overall  * * * * *Designed for fitness, fishing and surfing, it’s still a worthy timepiece for kooks and Barneys, thanks to the stunningly easy-to-read MIP display

The G-Shock is a line of watches manufactured by the Japanese electronics company Casio, designed to resist mechanical stress, shock and vibration. G-Shock is an abbreviation for Gravitational Shock. The watches in the G-Shock line are designed primarily for sports, military and outdoors-oriented activities; all G-Shocks have a chronograph feature, 200 metre water resistance and an alarm, with either a digital display, analogue display or a combination of analogue and digital displays. Other features such as a countdown timer, world clock, and a backlight are included in most models. Newer high-end models in the line also feature GPS, directional, pressure and temperature sensors and radio-controlled time adjustment known as WaveCeptor or Multi-Band.

The G-Shock was conceptualised in 1981 by Casio engineer Kikuo Ibe when he accidentally dropped and broke a pocket watch given to him by his father.bar and could survive a fall of 10 metres.

A team of three individuals was selected by Ibe which was known as "team tough". The team had assembled and tested nearly 200 prototypes but were still not able to achieve the conception criteria. During a visit to a playground, Ibe discovered that in a rubber ball, the centre of the ball doesn"t suffer the effects of the shock during a bounce on a rough surface which gave him the idea to implement that concept into the watch. With that in mind, the team set out to develop a watch using such a concept and in April 1983, the first G-Shock, the DW-5000C, was launched.

The shock-resistant design on the original G-Shock has 10 layers protecting the quartz timekeeping module,urethane rubber bumper, the stainless steel case, the hardened mineral glass watch crystal, the stainless steel screwed down caseback, and the "floating module" where the quartz mechanism floats free in a urethane foam cradle, with the outer buttons and LCD module attached with flexible cables. The strap of the watch is also designed to protect the module during a fall.

Initial sales of the G-Shock line were sluggish in Japan as people preferred dress watches. In order to promote the G-Shock worldwide, the American division of Casio released a commercial in which an ice hockey player used the DW-5000C as a hockey puck to demonstrate the toughness of the watch. The commercial gained negative publicity and Casio was accused of false advertising. A TV news channel then set out to conduct live tests on the DW-5000C to check whether it was as tough and durable as advertised. This involved repeating the action shown in the commercial. The DW-5000C survived the impact of the hockey stick, and the G-Shock gained popularity among the general public. The popularity of G-Shocks increased throughout the 1990s. By 1998, Casio had released more than 200 different G-Shock models, with worldwide sales at 19 million units.

In 1985, Casio released the DW-5500C, which was the first G-Shock to feature a mud-resistant structure. Called the G-Shock-II due to the new construction feature, it was nicknamed "Mudman" by collectors due to its construction. Casio would then go on to release a mud-resistant line of watches in 1995 which would go on to be called Mudman.

In 1992, Casio released the DW-6100 equipped with a temperature sensor thus making it the first G-Shock to be equipped with a sensor. The watch also featured a resin (plastic) case instead of the original stainless steel case of earlier models for improved shock resistance. This move would transition into most of the models in the subsequent years with the original G-Shock square design also adopting the same construction. By the early 2000s, the G-2000 model marked the last standard G-Shock to use a stainless steel case, leaving only a few speciality models in the line-up featuring the traditional metal case construction.

DW-8600 Fisherman (1996): First G-Shock having a tide-graph and moonphase feature. This model was a pre-cursor to the more popular Gulfman series first introduced in 1998.

In 1994, the DW-6600 model marked the transition to Electroluminescent backlight technology for G-Shock watches from backlights employing incandescent bulbs in earlier models.

In 1996, Casio released the MRG-100 model under its premium MRG lineup of G-Shocks which was the first G-Shock watch to feature full metal construction. The "floating module" concept was retained by cushioning the module between the metal case and metal bezel of the watch and an air-tight glass packing was added to improve shock resistance. Initially featuring a digital display, the MRG line would go on to adopt a full analog display featuring stepper motors for each hand and would be slotted as the top-of-the-line premium G-Shock lineup.

In 2008, Casio introduced the Tough Movement for high-end analog G-Shocks. The movement incorporates a light emitting diode (LED) photo receptor which analyses the position of the watch hands by the passage of light via a small hole in the dial. Every uneven reception of light by the phototransistor due to impact to the watch enables the stepper motors in the movement to correct the alignment of the hands requiring no manual adjustment. The hour, minute and second hands feature separate motors in order to allow for quick adjustment of the watch.

A similar series to the Baby-G called the G-Shock Mini was introduced in 2009. It is 30% smaller than a regular G-Shock and was originally marketed for women. However, they were later released in unisex variants intended for people who have smaller wrists. This series was later replaced by the S-Series in 2014.

In 2013 in order to celebrate 30 years of the G-Shock, Casio arranged a party in New York and showcased new models as well as various prototypes of upcoming models. The party included a performance from rapper Eminem.

The line of watches now includes atomic clock synchronisation and tough solar technology. Many newer models feature metal (steel or titanium) bands and a mix of analogue-digital timekeeping, analogue timekeeping or digital timekeeping.

The DW models are standard battery-powered G-Shocks while GW models of the G-Shock come with either Tough Solar or Multi-Band atomic timekeeping or both.

Twice a year, the basic models are updated. New limited models are introduced more frequently throughout the year. Special models are released upon the anniversary celebration of the G-Shock brand and are sold through selected retail channels.

Casio also produces collaboration models, often with popular fashion brands and artists, like A Bathing Ape (Bape), Stüssy,Eric Haze, KIKS TYO, Nano Universe, Levi"s, Lifted Research Group, as well as Coca-Cola, Pulp68 Skateshop, Lucky Strike and Marlboro.

G-Shock watches are popular with mountaineers, firefighters, paramedics, people working in the offshore, police officers, astronauts, film directors (Tony Scott was often pictured wearing a GW-3000B, as is Ron Howard and Francis Ford Coppola) and soldiers. Ex-Special Forces-British SAS soldier Andy McNab mentions in several of his novels how his character Nick Stone relies on a G-Shock watch. According to Mark Bowden"s book DELTA Operators wore G-Shock watches during the combat events of 3 and 4 October 1993. Since then, G-Shock watches have become very popular with Special Forces groups in both American and other NATO nation units, due to being "battle tested".

Casio continues to add new features to G-Shock watches. Some include Tough Solar battery charging and Multiband 6 time synchronisation through radio signals from six transmission stations worldwide.

In 2009, Casio introduced the GW-M5610, a solar powered variant of the DW-5600 incorporating Multi-Band 6 time reception technology and a design homage to the original DW-5000C which was an update to the earlier GW-M5600 model.

In 2012, Casio released the GB-6900 and GB-5600 which were Bluetooth-enabled models of the G-Shock giving them the ability to connect to a smartphone via an app, allowing the users to adjust various functions of the watch using the phone and receive notification alerts of the phone on the watch. There was also a phone-find feature which allowed the users to find the smartphone with which the watch is paired in case it is misplaced. The phone would ring regardless of the ringtone setting on the press of a button on the watch. Casio claimed the battery life of 2 years on a single CR2032 battery.

The GW-9400 Rangeman (introduced in 2013) and GWN-1000 Gulfmaster (introduced in 2014) models have a Triple Sensor with a digital compass, thermometer, and barometer/altimeter and were the first watches to receive such technology. The MTG-S1000, GW-A1000, and GPW-1000 feature Triple G Resist which includes resistance to shock, centrifugal gravity, and vibration. In 2014, Casio introduced the GPS Hybrid Wave Ceptor feature in the GPW-1000 Gravitymaster that allows the watch to synchronize the time through GPS signals and also adjusts the time zone automatically. The MRG-G1000 is also equipped with this feature.

At Baselworld 2015, Casio introduced the "Dream Project" (G-D5000-9JR) concept which was a Casio G-Shock square having most of its parts constructed of 18 Karat solid gold as part of the 35th anniversary celebrations of the G-Shock lineup. The watch featured premium finishes throughout its construction without compromising the basic shock resistance of a G-Shock. In 2019, Casio introduced the production version of the Dream Project which featured an upgraded module now incorporating Bluetooth time reception capabilities in addition to the radiowave time reception and began taking reservations at select G-Shock botiques in Japan. 35 units of the Dream Project square would be produced with each having a retail price of 7.7 million ¥ (69,500 US$ at 2019 exchange rates) excluding taxes making it the most expensive G-Shock watch to date.

In 2016, Casio released the GWN-Q1000 Gulfmaster which was first G-Shock to incorporate quad sensors (pressure sensor, temperature sensor, depth sensor and direction sensor). It was also the first G-Shock to feature horizontal calibration which allowed the compass to be operated while the watch is being worn by the user on the wrist. In addition to that, Casio offered every function offered on G-Shock models till date. The GWN-Q1000 is the only analog G-Shock to feature a depth sensor as well as the first G-Shock to have carbon reinforced polymer construction for the case.

In September 2018, to mark the 35th anniversary of G-Shock, Casio released a collection of four clear model of G-Shock watches called "The Glacier Gold" collection.

In late 2018, Casio introduced the newest addition to the G-Shock Rangeman series of models. The GPR-B1000 is a GPS centred model, which can use the GPS receiver to maintain the exact time, down to the second. This model also has triple sensors (altimeter, barometer and compass) as well as a backtracking function which allows the user to return to the same point from where he started the journey by the use of a map, a function which was previously exclusive for Casio"s ProTrek line of watches. The watch also features Bluetooth connectivity which allows it to connect to a smartphone via an app and allows it to upload log data in the phone, download map information from the phone and also synchronise itself with the phone in order to keep perfect time. The watch comes without a replaceable battery. The battery is either charged by solar cells present on the face of the watch (called Tough Solar by Casio) or via a wireless charger supplied with the watch, a first for a Casio watch.

In 2019, Casio released the GA-2100 which took design inspiration from the original DW-5000C but now incorporated an analog-digital display. Due to the octagonal bezel shape bearing a strong resemblance to the Audemars Piguet Royal Oak, the watch was nick-named "CasiOak" by fans. The use of the carbon reinforced plastic in the watch case allowed the watch to have a thickness of 11.8 mm, making it the thinnest G-Shock available as well as the lightest analog digital model with a weight of 51 grams. The aforementioned characteristics allowed the model to achieve increased popularity among collectors.

The Multi-Band 6 is a radio control technology first introduced on the GW9200 Riseman in 2008Wave Ceptor (which supported synchronisation with atomic time transmitters present in the United States and Japan only) technologies. G-Shock watches with Multi-Band 6 technology can synchronise with one of the six atomic time transmitters in the world in order to keep accurate time. The following is a list of the six atomic time transmitters:

Watches tune to the 68.5 kHz signal from BPC at Shangqiu. This is the newest additional signal; older multi-band 5 watches will not be able to connect to this signal, and must be upgraded to a newer multi-band 6 watch in order to synchronise from there.

On December 12, 2017, the G-Shock earned the Guinness World Record for the heaviest vehicle to drive over a watch. The officials from Guinness World Record drove a 24.97-tonne truck over the Casio G-Shock DW5600E-1. The G-Shock is the first watch by any company being able to withstand the challenge.

The Master of G series is the speciality line of G-shocks which were used to introduce new features that would eventually make their way to the standard production models. The lineup consists of:

These models were released in 1996, designed and specifically made for the surfing market. The countdown timers on these models were designed to count down for surfing competitions, some of the later models have a yacht timer, moon and tide graphs so a surfer can keep track of the progress while competing on the water. Many of these models came equipped with a pair of strap adapters and a single one-piece resin or nylon band. These styles of band are also known as "crossband" in the Japanese domestic market. Resin bands for these models had open gaps or slits through the band. Casio refers to them as drainage slits; the idea is that water will drain out with no problems while in action when surfing. Most of these series models had a translucent band. These models were branded as X-Treme for the Japanese domestic market.

These models are identical to the surfing editions, and also released in 1996. They were designed for snowboarding and skateboarding competitors and competitions. The only difference is that these models came with nylon velcro bands.

Atomic, world time, screw down caseback (GW-5000U-1JF only), Full auto LED backlight (Adjustable 1.5 or 3 second afterglow for light), Current time display in stopwatch and countdown timer mode

Titanium case/bezel, titanium alloy (DAT55G) band, COBARION bezel top, sapphire glass, screw down caseback, STN-LCD, Bluetooth, Day display in 6 languages

The camouflage – made up of characters such as Mudman and Frogman that were once engraved on the casebacks of G-SHOCK watches – adorns the black and white case and strap of a new DW-5600 reference.

The pattern extends onto the dial, forming the border of the reverse LCD display. As with other references of the same model, the DW-5600GU-7 is shock resistant, water resistant to 200m and features 1/100th-second stopwatch, countdown times, multi-function alarm, visual flash alert and back light.

To many, G-Shocks are seen as robust ‘daily beaters’; inexpensive and mass produced, yet tough enough to survive the harshest of conditions. But they are much more: a symbol of Japanese engineering and industrialisation prowess; or simply over engineered tool watches.

What would come to mind when one thinks of 100% in-house manufactured timepieces? Probably something from Switzerland or Germany. While Europe is a traditional stronghold of the mechanical watch, Japan is a master of ubiquitous technical innovations. Solar. Quartz. Just to name a few. It also happens to be the birth place of the ‘unbreakable watch’, a.k.a Casio G-Shock – something that perhaps only the Japanese can pull off.

This brings us to the subject of our discussion: the Casio G-Shock GMW-B5000. Launched during Baselworld 2018, the watch commemorates 35 years since the G-Shock’s debut. But is it still the “indestructible” watch that we’re all acquainted with? Without further ado, we present our detailed hands-on review of the watch. Except that this is not just any other GMW-B5000, but the author’s own.

Engineering such a feat proved to be a technical challenge – one that would take over 2 years with 200 prototypes tested. The final design incorporated 10 layers of shock protection, including a urethane rubber pumper and stainless steel screw down back. But its most ingenious innovation was the solution devised to protect its electronic quartz module: a free floating quartz mechanism suspended in a urethane foam cradle, with the outer buttons and LCD module attached with flexible cables. The final product was coined “G-Shock” – short for Gravitational Shock, and a term befitting the watch.

Sidebar: A G-Shock holds the current Guinness World Record for surviving the heaviest vehicle driven over it. We have also done our own robustness test. See the video here.  In addition, NASA has flight certified 5 G-Shocks models for use in space. All serves as a testament to its robustness.

The original G-Shock DW-5000C from 1983 (pictured above) is Casio’s first attempt at a shockproof, waterproof and practical watch – brainchild of Kikuo Ibe. Picture Credit: www.antiwatchman.com

In April 1983, the DW-5000C became the first commercially available G-Shock. The concept proved to be a commercial success, selling 19 million units by 1998. And in 2017, Casio shipped its 100-millionth G-Shock.

The first feature to strike the eye is its sleek metal case. Set from stainless steel, the GMW-B5000 is the first watch in the 5000-series to sport a full metal construction.

The GMW-B5000C sports a full metal construction – a first for the series. It retains the iconic rectangular case shape but with build quality that oozes quality.

The case retains the iconic rectangular form factor of the original but boasts none of the typical qualities you’d associate with G-Shocks: no sight of funky coloured rubber and plastics. Instead, its metal build oozes quality and feels premium in hand. And, we dare say it’s one of the nicest G-Shocks ever made – the blend of polished (not coated!) and brushed surfaces is well executed, giving it a bright and seductive appearance at every angle.

Finishing and detailing is what you’d expect from a watch at its price point: impressive but nothing quite breathtaking. It is done to a high engineering standard. Manufacturing is consistent throughout, with tight tolerances and every component fitting well. Perhaps a rather convenient grab-and-go everyday piece; robust yet chic. A slight niggle would be the buttons, which we found to be somewhat firm and occasionally requires a bit of fiddling to activate.

At 49.3mm by 43.2mm, this watch is, by G-Shock standards, conservatively sized. It sits well on an average wrist due to a 13mm case thickness and offers a palatable amount of wrist presence. (The author has smaller than average 5.5″ wrists and is able to pull it off.) It also has a good balance between heft and size – heavier than a Rolex Submariner at 167 grams, but wears comfortably once correctly sized. However, the fit may be slightly awkward due to its rigid end links, which sticks out and causes the watch to overhang.

Excellent viewing angles thanks to its super-twisted nematic (STN) display, and a improvement over its predecessor. Text appears sharp and are highly legible.

The watch uses a super-twisted nematic (STN) display with neutral-coloured background. Texts are crisp and highly legible. It offers overall excellent viewing angles, though the display can appear washed out at certain positions. Additionally, the watch is equipped with a Super Illuminator LED – Casio-jargon for LED backlight. It is senses ambient light and light up accordingly, ensuring a effortless time-telling experience in all situations. There is no brightness control, but the backlight has a nifty ‘fade-in/fade-out’ feature which is easy on the eyes, especially so in darkness.

Surrounding the LCD are solar cells which enables the watch to be recharged when exposed to a light source. They feature the iconic “brick” pattern which harks back to the original. A flat bezel protrudes from the case providing protection to the LCD and solar elements.

The stainless steel integrated bracelet contributes a major part to how this watch looks and feels on the wrist. It meets the case effortlessly and harmonises the full metal aesthetics, sprucing up its handsome appearance. It features circular motifs which are indented near the edges – a design which harks back to the original rubber. Additionally, there is optimum built-in ‘stretch’ and flexibility, ensuring a comfortable fit on the wrist. Finally, the bracelet is complimented by a metal folding clasp which feels sturdy when opening and closing.

An interesting design quirk are its links. Instead of conventional push pins or screws, the bracelet is held together by spring bars which sits at the center of each link. In addition, the bracelet also does not include half-links, though the micro-adjustments holes on the clasp suffice. Nonetheless, they are well-sized and wraps around the wrist nicely.

The timekeeping function is typically regulated by the Multiband receiver, which syncs with 1 of 6 radio transmission stations across the world. They are located in North America, UK/Europe, China and Japan. Suffice to say, Casio has built-in support for 30 and 45-minutes time zones and Daylight Saving Time – talk about “Grand Complications”.

However, some countries and cities are out of covered range by these towers and will not able to receive the transmissions. The ‘G-Shock Connected’ mobile app compensates for this, though, an active Bluetooth connection is needed. In our testing, we barely used the app as the watch kept accurate time out of the box. There is also no official word on battery life, but 8 minutes of sunlight exposure is enough for a full day’s usage.

In the area of tough tool watches, a G-Shock faces very little competition. There is simply nothing from the Swiss, let alone the entire market, which can match up to its ‘quality/function/price ratio’ – if there is one.

That being said, the GMW-B5000D-1 has a recommended retail price of S$799. Rather steep, especially when considering its functionality and compared to some of Casio’s other lineup. Thus, whether ‘good-value’ is warranted is entirely up to the reader.

We kick things off with the Victorinox I.N.O.X. (ref. 241682.1) – perhaps the toughest and most resilient watch on this list. It’s not an unwarranted claim, as the brand has thoroughly tortured this watch by subjecting it to over 130 test. The toughness is manifested in the design, which features a chunky metal bezel and removable rubber bumper. In addition, a sapphire crystal is used to protect the dial. The watch is encased in a 43mm stainless steel case and powered by a Swiss Ronda quartz movement. The I.N.O.X retails for US$525 – rather good value, considering its all-round versatility.

Next, we propose the Tissot T-Touch Expert Solar (ref. T091.420.44.051.00). It features a titanium case with matching bracelet and a slew of functions, including altimeter and barometer. But the standout function would be its ‘dial’: instead of a conventional setup, the watch utilises a convenient touchscreen which allows for tactile operations. It is protected by a scratch-resistant sapphire crystal with anti-reflective coating. And rather impressively, the touchscreen is able to be powered by solar energy. The Tissot has a recommended retail price of US$1,250.

The Luminox Navy SEAL 3500 series is another contender. As its name hints, the timepiece is closely associated with the United States Navy SEALs. No questions about its durability. The watch has several standout features, including tritium gas tubes and a sturdy carbon case. It is powered by a Swiss Ronda Quartz movement which lasts 8 years on a single battery. The Luminox has a recommended retail price of S$695.50.

The Breitling Emergency II is the most innovative watch on this list. Designed for professionals, it’s the only timepiece which boast a personal locator beacon (PLB). The watch is powered by the Breitling caliber 76: a thermocompensated SuperQuartz™ movement that is COSC certified. All that technology is packed in a 51mm titanium case with a rechargeable battery providing 2 years of battery life. The Breitling retails for S$21,000.

A mechanical ‘contender’ would be the Richard Mille RM 53-01 Tourbillon Pablo Mac Donough. Designed (and tested) to withstand 5000 g’s of shock, it is the ultimate manifestation of a sports watch. (In contrast, a typical G-Shock can withstand 15 g’s). However, acquiring one might prove a challenge as its limited to 30 pieces and, probably a deal-breaker, priced at a cool USD900,000.

The Casio G-Shock GMW-B5000D-1 is as you’d expect with all other G-Shocks: tough as nails yet possessing a certain panache. Its sleek, full metal construction is a departure from the norm of G-Shocks and makes for a rather capable casual timepiece. Despite several design quirks (all of which easily forgiven), this watch is possibly one of Casio’s all-time best executions.
