Sharing a passion for blazing new trails, Hotei and G-SHOCK continue to explore a special relationship as pioneers in their respective fields. And the result is another uniquely tough timepiece designed for the rock scene.
The very first G-SHOCK — the DW-5000 — debuted in 1983. Its timeless design, perfected right from the beginning, was born of a pursuit of the ultimate toughness eschewing all hints of the extraneous.
A design concept soon inherited by the first analog G-SHOCK model — the AW-500 — released in 1989. This concept was realized with a rock-solid design that looked almost like it was carved out of a single block of resin, removing everything non-essential.
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.
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.
Paris, Hamburg, New York and Shanghai… impressions gathered from points all around the globe informed the design work. Countless sketches were made, and designs drawn and reviewed in a process of painstaking trial and error. At last a new watch was born, featuring a minimalist design with an octagonal bezel.
This was no design merely pursuing simplicity. The designers’ intent inspires the GA-2100 down to the finest details, like dimensional dial and index. The monochromatic color scheme features an optimized combination of hues hand-selected from a range of color charts.
With pride in its unchanging form, the G-SHOCK mission is one of continuous advancement, always transcending the times, conventional wisdom, and the limits of imagination. With a toughness emblematic of the new era, the GA-2100 has arrived.
An appearance slim, compact, and simple intentionally overturns the notion that G-SHOCK watches are always massive. Heir to the essence of the very first G-SHOCK, the GA-2100 delivers the very essence of functional beauty. The ultimate in minimalist design for contemporary lifestyles.
The bezel features the octagonal design motif maintained since the very first G-SHOCK. The outline a sense of stability, creating an expression of power worthy of the G-SHOCK.
Use of the latest toughness-driven construction with carbon fiber-reinforced resin made it possible to slim the case to the utmost limit. The side profile design pays homage to the very first model with its button layout, uneven surface form and fixed-angle band.
With a sense of depth achieved with three-dimensional molding, the dial features a minute-mark-notched dial ring, three-dimensional index cuts, a mode dial and irregular shaped LCD in a sweetly balanced arrangement. The spacious layout makes for a face design offering simplicity as well as excellent visibility.
The GA-2100 line comes in a thoroughly fashion-conscious color scheme. The GA-2100-4A boasts 9 different shades of red. The application of a different shade for each component — from the case exterior to the dial, dial ring, hands, LCD, buckles and more — gives the watch an overall integrated look, while bringing out an irresistible textural feel in its detailing.
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.
The developers pursued a thinner design while still satisfying the original G-SHOCK criteria for shock resistance. They strengthened the external structure and slimmed the module, achieving wafer-thin at just 11.8mm.
The module was slimmed by miniaturizing the componentry and employing optimized, high-density mounting for the circuit board structure. Combined with the Carbon Core Guard structure, these efforts made for an astonishingly smaller, slimmer case.
The double LED with high luminance brightly illuminates the dial and LCD to ensure readability in the dark.
A slide lever makes it easy to attach and remove the band — a very handy feature for cleaning and other maintenance.
The shock-resistant structure protects the watch. With 200m water resistance as well, the watch is ideal for use in a wide range of locations and situations.
The “BAR” value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked “200m” have the same water resistance as 20 BAR watches
Shock-resistant construction protects against impact and vibration
Full Auto Super LED (Double)
5 Multi-function alarms can be configured to sound on a particular date, a particular day of the week, or at the same time each day. The number indicates the number of alarms. The hourly time signal causes the watch to beep every hour on the hour
(1/100 24HR) Accurate measurement of elapsed time with the touch of a button. The fraction indicates the unit of measurement, while the time figure indicates the maximum time measurement
24 Hour
Allowances are made automatically for months of different lengths, including leap year

MINERAL GLASS - Hard glass resists scratching
When a hand overlaps the LCD, the hour and minute hands are retracted temporarily to ensure LCD visibility.
