In 1983, G-SHOCK established a new genre of toughness in watches by embodying the idea of breaking the common sense of shock-resistant structure with the first model DW-5000C.
The history of constant evolution finally reaches the milestone of the 40th anniversary.
Structure, function, materials and design. We stick to all of them without compromise and pursue further toughness.
The aim was robustness that could be used in any environment.
Practicality that works reliably under any circumstances.
All to fulfill the ultimate goal of being almighty tough.
Now and in the future. Proud to be tough.
Aiming for even greater heights, G-SHOCK's challenge continues.
Real toughness inherited beyond the times is here.
40th Anniversary Since 1983
Challenge The Limits



EVOLUTION
CHALLENGE
FOR
ABSOLUTE TOUGHNESS
Seeking greater strength, aiming for greater heights.
Endless challenge to support the evolution of G-SHOCK.
STRUCTURE
Toughness structure that can withstand the extreme.

1983
Impact resistant structure
Hollow structure, omni-directional guard structure, and cushioning material protection for important parts improve durability against drop impact and vibration.

1995
Mud resist structure
All buttons are covered with urethane material, and a dust-proof and mud-proof structure that shuts out dirt and dust is adopted.

2012
TRIPLE G RESIST
A reinforced structure that withstands three types of gravitational acceleration: impact force, centrifugal gravity, and vibration. Uses α-Gel®, which has excellent vibration absorption, as a measure against vibration.

2013
Core guard structure
The frame consists of a bezel, back cover, and stainless steel pipe to protect the inner case. The concept of a hollow structure is realized with a metal exterior.

2014

2017
New layer guard structure
We have developed a new structure that places resin cushioning parts inside the case, pioneering a new frontier in toughness design.

2018
Full-metal shock-resistant structure
Fine-resin cushioning parts are inserted between the bezel case and the inner case. Besides achieving a highly accurate fit, this structure responds with reactive force to ease shocks when tiny protrusions in the cushioning material are compressed.

2019
Carbon core guard structure
Offering strength, lightness, and excellent durability, the carbon fibre-reinforced resin case protects the module.

2021
Slide lever changeable band
The band can be replaced easily by operating a lever at its base.
MATERIAL
Ongoing pursuit of new materials

1983
Urethane resin
Adoption of lightweight, easy-to-process urethane resin as a case material, significantly expanding the range of possibilities for form, design and color.

1996
Full-metal Case
Development of an elaborate exterior design and reinforcement of the module to realize a shock-resistant full-metal case structure.

1999
Metal Twisted Design
Completion of a tough design of remarkable “functional beauty” that combines strength and beauty in a case constructed of both metal and resin.

2010
Carbon-fiber Insert Band
Realization of a remarkably tough band by inserting a carbon-fiber material with superior tensile strength into resin.

2015
Titanium 64 Bezel
Adoption as the bezel material of titanium 64, which boasts greater strength than pure titanium while retaining titanium’s characteristic lightweight and corrosion resistance.

2017
Carbon Bezel
A bezel constructed of a lightweight, high-rigidity carbon material produced by applying microstructure control technology to combine state-of-the-art carbon fiber with resin.

2019
Carbon fiber reinforced resin case
The shock-resistant structure unique to G-SHOCK protects the module, with a carbon fibre-reinforced resin case offering strength, lightness, and excellent weather resistance.

2020
Fluoroelastomer Band
The fluoroelastomer material provides an excellent fit on the wrist with its soft feel, not to mention exceptional resistance to staining and hydrolysis.

2021
Titanium Alloy
An entirely new alloy developed for G-SHOCK with a hardness exceeding that of pure titanium offers excellent processability and suitability for mirror finishing.

2022
Biomass plastic
Using renewable organic resources such as castor oil plants and corn helps reduce the ecological footprint.

1992
Sensor Technologies
Practical application of various miniaturized sensors, beginning with a temperature sensor, to take measurements of such environmental phenomena as directions, atmospheric pressure, altitude and water depth.

1994
EL Backlight
Development of the EL backlight, a highly practical dial lighting function.
