#NEVERGIVEUP: THE STORY OF THE G-SHOCK

In 1981, Kikuo Ibe, at that time an engineer in CASIO's research
and development department in Tokyo, 
dropped the watch his father had once given him.
The watch broke, spurring him on to develop the ethos
of creating the first 
indestructible watch that could withstand adverse circumstances.

 

He founded "Project Team Tough",
to make his project a reality.
Two years later, in 1983, after throwing more than 200
prototypes off the roof of the Tokyo building,
the first shock-resistant,
water-resistant G-SHOCK
with a battery life of 10 years was born.

 

This unwavering persistence is the foundation of G-SHOCK's philosophy,
which has continued for nearly four decades to this day.

DEVELOPING ICONS SINCE '83

Following its release, the G-SHOCK quickly became successful.

Initially, it was worn by skateboarders because of its robustness,

before gaining prominence in street culture. It became

a hip accessory in the world of music, fashion and sports,

as well as the urban artistic scene.

 

We are continuing our success story with the new 2100 version,

which bears the same colours as our iconic DW-5600 of the 90s.

DETAILS

The first digital G-SHOCK DW-5000 was launched in 1983 and was born out of a desire to build the most durable digital watch imaginable. And one that was light and efficient. In 1989, the first analogue model by G-SHOCK followed with the AW-500.

In 2019, G-SHOCK set out to create the ultimate in robustness with a new aesthetic case design, combining both analogue and digital functions — the GA-2100 was born. It represented G-SHOCK's continued evolution while retaining the iconic elements of past icons of the DW-5000 and AW-500.

The new GA-B2100 is now fully solar-powered, and this function works via any light source.

Your watch charges from artificial or natural light, a sustainable power source that keeps your G-SHOCK "ticking" day and night. Just eight minutes of sunlight is enough to power the watch for a whole day. No change of battery, just months of energy reserves and great reliability.

Control every function of your 2100 wirelessly from your smartphone —  from daily alarms and countdown timers  to the stopwatch.

TECHNICAL FEATURES

Resin strap

Resin is the perfect material for straps thanks to its durability and flexibility.

5 daily alarms

The daily alarm reminds you of events that recur every day, by emitting an audible signal at the set time. This model has five independent alarms, making it especially convenient for taking daily medication or keeping regular appointments.

Super Illuminator

At the push of a button, the dial or display of the watch is illuminated particularly brightly and colourfully, so that you can see everything even in absolute darkness.

Hand moving function


At the push of a button, the hands reveal the view of the digital displays, so that the stop function or day of the week, for example, can be read without restriction.

Carbon-reinforced resin casing

Individually, carbon and resin are resilient and durable — in combination, they form a case that makes the watch even more resistant and insensitive to dust, shocks, heat, cold or humidity, thus offering particularly long durability.

phone finder

Misplaced your smartphone? Just press a button on the watch and the smartphone sends an alarm.

Neo display

The hands and/or index are fluorescent-coated and glow in the dark when the watch has previously been exposed to a light source

Bluetooth® Smart

The watch is equipped with energy-saving Bluetooth® technology, which offers power-saving data transfer at the push of a button. The watch can connect to a smartphone wirelessly via Bluetooth®, enabling access to a wide range of useful functions.

Shock-resistant

You can do a lot with this watch, without it becoming damaged. The impact-resistant housing offers protection against impact and vibrations.

Accurate time via smartphone

If the watch is paired with the smartphone, the time is set automatically and thus shows the current local time worldwide.

Mineral glass

The tough, scratch-resistant mineral glass protects the watch against unsightly damage.

Solar-powered

Solar cells provide an independent and environmentally friendly source of power. Any excess solar power is stored in a battery.

Pin buckle

The strap is equipped with a pin buckle.

Stopwatch: 1/100 sec.–24 hours

For athletes and all those who want to measure time precisely: Time lapsed, interval time and end time are measured to the nearest one-hundredth of a second. The watch has a timing capacity of up to 24 hours.

Water resistance classification (20 bar)

Perfect for freediving without equipment: The watch is tested for water resistance up to 20 bar according to ISO 22810.

Automatic calendar with date, month and weekday

Once set, the automatic calendar always displays the correct date.

Key tones on/off

The key tones can be turned off as and when required using the mode button. This therefore means that the watch no longer beeps when switching from one function to another. Set alarms or countdown timers are still active after the key tones are switched off.

12-/24-hour format

The time display can be set to either 12-hour or 24-hour format. In 12-hour mode, a "p" in the display represents the second half of the day, i.e. 12 noon to 11:59 pm.

Multilingual weekday display

Monday, "Montag" or "lundi"? You can decide for yourself in which language the weekdays should be displayed. This model works multilingually.

Timer — 1/1 sec. — 24 hrs.

For fans of precision: The countdown timer helps you to remember special or recurring events by sounding an audible signal at a set time. The time can be set down to the second and up to 24 hours in advance.

 

World time function

The world time function displays the times in up to 29 different time zones.
