The movement also supports a full calendar, displaying the date, day, hours, minutes, and seconds, while ensuring perfect synchronization through multifunction settings. This solid, reliable technological core makes this model the ultimate companion for those who never stop.

The Strap

Comfortable and durable, the strap of the GravityMaster is crafted from resin and urethane, two materials renowned for their resistance to the elements and their flexibility. Its gray color gives it a modern, refined look that pairs seamlessly with the rugged case. The strap fastens with a pin buckle, ensuring a secure fit and easy adjustment. The use of modern materials delivers exceptional wearing comfort even in the harshest conditions, whether on an outdoor expedition or during everyday urban use. Its one-piece construction also provides stability that prevents deformation, preserving the watch's aesthetic and functional integrity over its lifetime.

Water Resistance

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