Layers of metal and fine resin combine to create the stylish G-STEEL collection.
Don’t be fooled by the sleek appearance, behind handsome exteriors lies the renowned G-SHOCK DNA.
Smart enough for the office, tough enough for the expedition.
Wherever life takes you, your G-STEEL can take it.


Sleek and polished, but infamously hard-wearing, stainless steel provides a scratch-resistant and protective casing, with a timeless metallic finish.


A solar panel converts even weak illumination from fluorescent lighting into electric power. A rechargeable battery with a large power storage capacity supports stable operation of various functions with high electricity consumption. You never have to worry about the battery running down because it's a solar battery.


Shock-resistant construction protects against impact and vibrations. This technology has been passed down to every G-SHOCK model for over a quarter-century.


The carbon composite bezel is constructed of resin amalgamated with a lightweight, highly rigid TORAYCA®*1 carbon-fiber material developed by applying NANOALLOY® technology.*2 After layers of unidirectional fibers are alternately stacked in the vertical and horizontal directions and bonded together, the resulting laminated material is cut into the form of a bezel. It is then finished in a pyramid-shaped design inspired by an metal file. (GSTB100X & 100TFB only)


The G-Steel’s layered guard structure boasts a double-layer bezel construction of stainless steel and resin or resin and fine resin which delivers the hard, sleek beauty of metal while retaining the impact absorption of resin.


A indicator inspired by jet engine blades is mounted at 9 o'clock. The battery level and remaining time on the timer are indicated by a red marker that is visible through the clearance of the blades. (GSTB100 Series Only)


Two white LED lights cast brilliant illumination on the hands and LCD. Their use in combination with phosphorescent coating ensures excellent legibility in the dark.


The exact time is set automatically by smartphone four times a day. The time in any of 300 cities worldwide can also be displayed promptly with a simple operation on a special smartphone application. (GSTB100 Series Only).

In 1983, CASIO engineer Kikuo Ibe won the battle against the laws of nature. He designed a watch that
would resist centrifugal and impact forces, as well as high water pressure. It took over 200 prototypes,
over a period of two years until he finally arrived at his iconic watch design.

Since then, G-SHOCK has mastered ‘absolute toughness’ through its rigorous testing and use of the most
durable materials. The ‘Master of Metal’ collection brings together our range of unique metal watches,
which are both tough and beautiful.
