G-Shock is a premium line of shock-resistant watches manufactured by the Japanese electronics company Casio. Launched in 1983, G-Shock transformed the watch industry by demonstrating that a wristwatch could be exceptionally durable whilst remaining functional, stylish, and technologically advanced. Today, G-Shock is recognised globally as one of the most iconic watch brands, particularly among athletes, military personnel, outdoor enthusiasts, collectors, and fashion-conscious consumers.1

The origins of G-Shock date back to 1981, when Casio engineer Kikuo Ibe accidentally broke a watch of sentimental value. Determined to create an “unbreakable watch”, he established Project Team Tough with a small group of engineers.

After developing more than 200 prototypes over nearly two years, the team released the DW-5000C, the first G-Shock model, in 1983. The breakthrough lay in a revolutionary hollow-case construction that protected the internal module from shocks, enabling the watch to survive drops that would destroy ordinary timepieces.2

The original design was founded on the Triple 10 concept:

• Survive a 10-metre drop
• Provide 10-bar (100 m) water resistance (later increased to 20-bar/200 m)
• Operate for 10 years on a single battery

These ambitious targets established G-Shock’s identity as the world’s toughest watch.1

G-Shock’s core philosophy is “Absolute Toughness”. Rather than designing delicate luxury watches, G-Shock focuses on creating timepieces capable of withstanding:

• Strong impacts
• Heavy vibration
• Mud and dust
• Extreme temperatures
• Water pressure
• Everyday abuse

The brand continuously develops new materials, structures, and technologies to enhance durability without compromising comfort or style.2

Over four decades, G-Shock has introduced numerous innovations, including:

Shock Resistance

The signature floating-module construction protects internal components from impacts.

200-Metre Water Resistance

Nearly every G-Shock model is rated for 200 metres of water resistance, making them suitable for swimming and many water sports.

Tough Solar

A solar-powered charging system that reduces the need for battery replacements.

Multi-Band 6 Radio Control

Automatically synchronises time using atomic clock radio signals in supported regions.
