The G-SHOCK MASTER OFG series supports activities in harsh environments

The base models are the GRAVITYMASTER, MUDMAN, and RANGEMAN, which support activities in the air and on land, and feature a black body that symbolizes toughness and a caution color of yellow for the band.

It expresses the worldview of professionals who take on tough missions at rescue sites and other places.

The GRAVITYMASTER GR-B300RY expresses an organic form inspired by next-generation aircraft with a seamless exterior design.

Carbon core guard structure and 3D wide face for durability, visibility, and comfort

It also has practical functions such as dual time, which displays the time in two cities simultaneously, and flight log, which allows you to manage your travel history.

The MUDMAN GW-9500MRY is shock-resistant, dust-proof, mud-proof, radio-controlled solar-powered and triple-sensor-equipped.

The use of a duplex LCD improves the visibility of the direction display, making the digital compass even more useful.

In addition, stainless steel is used for the bezel parts.

Black IP coating gives it a bold design.

The RANGEMAN GPR-H1000RY is shock-resistant, dust-proof, and mud-proof, and is equipped with six sensors including a heart rate monitor, as well as a GPS function that can measure position, distance, and speed.

Measures nine types of activities in real time, including trekking

This is a tough watch that supports quick judgment and precise action even in harsh environments.
