G-SHOCK pulled off its astonishing debut in 1983 as a tough watch that would not break even if dropped. The brand has incorporated a diverse array of cultural influences since then, continuing to evolve in a way unlike any other.

The origin and its evolution, each inspired by its own special spirit of toughness. The GA110 and GM100 create G-SHOCK history in a new special way.

Setting Sights on New-Generation Analog Watch

A new trendsetter, when digital was mainstream for youth-oriented models of the day, the GA110 was designed to present an analog model like nothing the world had ever seen before. It was a turning point that set the historical trajectory of the ever-evolving G-SHOCK brand into serious motion.

Taking It Even Higher: Evolution in Year 10

The year 2020 saw the appearance of the GM110, featuring a metal-clad exterior. Heir to the identity of the GA110 with its large case size and mechanistic face, the GM110 presents a legitimate evolutionary progression with its ever-more-industrial semblance.


Laminated Dial

The four-layer parts arrangement presents an impression of depth. Dimensional molding and metallic-toned coloration give the iconic Y-shaped part an ingot-like texture in its finish.

Hand Shapes

Large-sized hour and minute hands reinforce the impression of solidity with their simplicity. Crafted with particular attention down to the minute details, with features including punching and luminescence.

Band Design

The watch employs a simple, thick resin band. Industrial-style geometric patterns on the surface give an impression of depth.

Super Illuminator

High-intensity LED lights up the watch face with high-intensity light, maintaining watch readability in the dark.

Magnetic Resistant

JIS1 magnetic resistance is achieved with a magnetic-resistant plate mounted in the module. This prevents magnetism-caused hand deviation.

Battery Life of about 3 years

A newly designed module delivers power-saving benefits to achieve extended battery life of about 3 years, up from conventional models’ 2 years.


Metal-Covered Shock-Resistant Structure

The bezel is crafted with metal material. Minute protrusions on the inner case reduce surface contact with the bezel to cushion shocks to the module.

Glass Fiber Reinforced Resin Inner Case

Glass fibers are incorporated into the resin for increased strength. The material’s resistance to breakage and bending protects the module from external shock.

Forged and Molded Bezel

Undergoing about 20 forging processes, as well as cutting and polishing, the bezel is precisely crafted from a highly uneven molding to a back surface shape that determines the precision of its assembly.

– Hairline and Mirror Finishes [GM110]

Circular and radial hairline finishes are applied to the raised and low portions of the bezel, and the slanted surface is polished to a mirror finish.

– Gold Ion Plating (IP) and All-Mirror Finish [GM110G]

Mirror finishing is applied to the metal bezel. Gold coloration is achieved with an IP process.


A Vision of Toughness × Steampunk

A series with roots in Steampunk, a popular sci-fi genre with subcultural appeal, where gargantuan structures encompassing powerful steam engines and complex, intricate control mechanisms exude senses of heft and bulk. With inspiration drawn from Steampunk’s retro-futuristic vision integrating street sense with technological savvy, the concept of a steam-powered G-SHOCK was born.

Original Design Combines Large Case and Layered Dial

Going back to zero in development, and pursuing every minute detail, delivered a design that set the series apart from any conventional analog model. Staggering repetitions of shock resistance-focused trial and error led to new part molding and configuration.
Case sizes were among the largest in the G-SHOCK line. Rivet-style design throughout made for a powerful, rugged look, while the dial featured four-layer lamination. A pairing of gear-shaped hands with a steam engine shaft-inspired Y-shaped part lent a mechanistic edge to the face. The increased number of intricately detailed parts—achieved with original Casio processes—enabled multi-color exteriors as well.

All-Time Record, No. 1 Sales Worldwide

The GA110 made its debut in 2010 with a hyper-complex look that rapidly won over young people worldwide. It went on to develop into a dazzling array of variations and collaborative efforts involving a range of cultural influences. Ten years on from its inception, the GA110 has carved out an unshakeable iconic status for itself as a top G-SHOCK seller worldwide.
