Lineup of GA2100 Thin Watches for Men
A Thin Analog-Digital G-SHOCK Watch
G-SHOCK watches are widely recognized for rugged durability, and some models emphasize larger case designs built for extreme environments. The GA2100 series takes a more streamlined approach. Measuring approximately 11.8mm thick, it is among the slimmest analog- digital G-SHOCK models, offering 200m water resistance and shock protection in a refined profile designed for everyday wear, including under shirt cuffs.
The new style G-SHOCK
GA2100 Carbon Core Guard Structure for Advanced Protection
The slim profile of the GA2100 is made possible by G-SHOCK’s Carbon Core Guard structure, which uses carbon fiber–reinforced resin to strengthen the case from within. This construction enhances rigidity and shock resistance while minimizing weight, supporting the watch’s streamlined 11.8mm thickness. By reducing material mass without compromising durability, the Carbon Core Guard structure enables the GA2100 to deliver full G-SHOCK toughness in a more refined silhouette. It is advanced protection engineered for everyday comfort.
G-SHOCK GA2100: Slim G-SHOCK in an Analog-Digital Design
Known for tough digital watches, the G-SHOCK GA2100 lineup launched the 2100 series in 2019, offering a thin module and analog-digital watch face. A large, clear dial dominates the face, offering a classic look to the octagonal design. The GA2100 series also sports a smaller second dial for the day of the week, adding a mechanical layer to the hybrid face. The digital LCD incorporates a modern functionality and aesthetic to the dial, giving you the performance of both styles in a unified look. The digital LCD can cycle between month/day and hour/minute in Timekeeping mode, display World Time, and display the timer, stopwatch, and alarms. G-SHOCK design and ingenuity crafted a slim watch in a signature analog-digital design with legendary G-SHOCK toughness and 200-meter water resistance. That's the GA2100 series.

The New Style G-SHOCK
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.
Octagonal Bezel
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.
Minimal Design
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.
Dimensional Dial
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.
Monochromatic Color
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.
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.
The Challenge of a Thinner Case
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.
Thin Module
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.
Double LED Light
The double LED with high luminance brightly illuminates the dial and LCD to ensure readability in the dark.
Slide Lever
A slide lever makes it easy to attach and remove the band — a very handy feature for cleaning and other maintenance.
Shock-Resistant Structure and 200m Water Resistance
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.
