The GA-2100 Series

The GA-2100

The first GA-2100 watch was introduced in 2019, expanding the possibilities of toughness and analog style. Heir to the DW-5000 and AW-500’s conceptual design frameworks, it leveraged the latest technologies to capture the essence of their identities in a new physical form. This meant nothing short of creating a new standard-bearer for G-SHOCK, re-envisioned from the vantage point of the brand’s beginnings, now some 30 years after the AW-500’s debut.

New Technologies, New Design

The development concept: slim and compact. The determination to eschew the extraneous realized not just in design, but in size as well. It took revolutionary new technologies — from the thin module to the Carbon Core Guard structure — to achieve this. Distilling the very essence of the original DW 5000 design, the watch introduces a reconstructed form that is sure to integrate smoothly with contemporary lifestyles and fashion.

Carbon Core Guard Structure

The module is protected with a carbon fiber-reinforced resin case. The special characteristics of the carbon fiber material — light weight, high strength and superior weather resistance — were leveraged to make the case as slim and compact as possible, with no compromise on shock resistance.



All features

LED light
A light-emitting diode (LED) is used to illuminate the watch face.
Shock-resistant
Shock-resistant construction protects against impact and vibration.
Neo-display
A luminous coating provides long-term illumination in the dark after only a short exposure to light.
World time function
The world time function displays local times in up to 29 different time zones.
Stopwatch function - 1/100 sec. - 24 hours
Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours.
Timer - 1/1 sec. - 24 hours
For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. They The time can be set to the nearest second and up to 24 hours in advance.
5 daily alarms
The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments.
Hand Moving Function
With a push of a button, hands are moving and permit a free visibility of functions like stopwatch or date.
Button tones on/off
The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated.
Automatic calendar with Date, Day and Month
Once set, the automatic calendar always displays the correct date.
12/24-hour format
Times can be displayed in either a 12-hour or 24-hour format.
Mineral glass
The tough mineral glass resists scratching.
Carbon-reinforced resin casing
Thanks to its extremely high level of durability, resin is the ideal material for watches. Combining resin with carbon—a particularly robust material—creates a casing that is even more stress-resistant and offers even greater protection against external influences, resulting in an extremely high level of durability.
Resin band
Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties.
Buckle
The bracelet is equipped with a buckle.
3 Years - 1 Battery
The battery supplies the watch with sufficient energy for approx. three years.
Water resistance classification (20 bar)
Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810.
Chronometric precision
+/- 15 Seconds per month
