Inheritance towards a Thin Watch

The new style G-SHOCK

Design of a Watch
for Everyday Use

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.

G-SHOCK Technology
in a Thin Watch

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.
