Its octagonal case is crafted from stainless steel, a material renowned for its exceptional resistance. The case measures 56.70 mm in length, 47.30 mm in width, and 14.10 mm in thickness, ensuring a bold and robust wrist presence. The total weight is 102.00 g, combining solidity and comfort.

The Movement

Beneath the dial, the watch houses an advanced solar movement refined by Casio, delivering both exceptional accuracy and remarkable energy efficiency. This Japanese mechanism draws on natural and artificial light to power the watch, eliminating the need for battery changes. It integrates advanced functions such as a chronograph capable of measuring down to 1/1-second, a countdown timer, and world time zone management, ideal for globe-trotters. The movement also handles the complete calendar, displaying the date, day, hours, minutes, and seconds, while ensuring perfect synchronization through its multifunction settings. This solid, reliable technological core makes this model a perfect companion for those who never want to stop.

The Strap

Comfortable and built to last, the GravityMaster strap is crafted from resin and urethane, two materials prized for their resistance to the elements and their flexibility. Its gray color delivers a modern, refined look that pairs perfectly with the robust case. The strap closes with a pin buckle, providing a secure hold and easy adjustment. The use of modern materials offers a unique wearing comfort even in the most demanding conditions, whether on an outdoor expedition or during daily urban use. Its one-piece construction also ensures stability that prevents any deformation, preserving the aesthetic and functional integrity of the watch throughout its lifetime.

Water Resistance

The G-Shock GravityMaster delivers exceptional water resistance up to 20 ATM, the equivalent of 200 meters underwater, making it ideal for aquatic activities including deep-water diving. This capability is reinforced by the screw-down crown and the screw-locked caseback, guaranteeing optimal protection against water infiltration.
