Part of the Master of G — Air line, the Gravitymaster is built for people who work in difficult places.
A metal bezel in light yellow gold ion plating sits over a Carbon Core Guard case in carbon fibre-reinforced resin, with brown ion-plated components and a dark brown bio-based resin band. Large raised indexes and a rotary disc indicator at nine o'clock, driven by a dual-coil motor, handle alarm status, stopwatch and battery level. Tough Solar means no battery changes, Bluetooth keeps the time exact, and water resistance runs to 200 metres.

Built not to break

A module that floats
Inside a hollow case, the module (the heart of the watch) seems to float, so knocks from outside are softened before they reach it. The idea came from watching children play with a rubber ball.
Tough Solar
A thin, film-like solar panel is fitted into the dial around the display, and it turns even weak light, such as from fluorescent lamps, into power.

2-year warranty
Every G-SHOCK watch from Watch Direct comes with a 2-year warranty from Shriro Australia, Casio’s exclusive Australian distributor.
Watch Direct is an authorised G-SHOCK retailer, trading since 2011.

About G-SHOCK

G-SHOCK began with a dropped watch. Casio designer Kikuo Ibe saw a watch break when it fell, and proposed “a durable watch that would not break even if dropped”. The project set itself the “Triple 10” goal: survive a 10-metre drop, resist water to 10 bar and run for 10 years on one battery. The first G-SHOCK, the DW-5000C, arrived in 1983.
