G-Shock Master of G GRAVITYMASTER All Black Men's Watch GRB200-1B
Brand-New, 100% Authentic. We are an Authorized G-Shock Retailer. Includes G-Shock Backed Warranty at no extra charge.
These Quad Sensor Bluetooth connected G-SHOCK Master of G “GRAVITYMASTER” GRB200 models pack flight mission essential functions into a tough and rugged carbon core guard structure.
A high-strength, highly weather-resistant Carbon Core Guard Structure protects the module with a resin case reinforced with carbon fibers. This, combined with world-renowned G-SHOCK shock resistance, creates a structure that is also highly vibration resistant. The bezel is made up of three layers of resin with carbon fiber inserts. The top layer is semi-transparent to reveal the carbon material inside. The three buttons on the right side of the watch are arranged in a way that makes them resemble a fighter jet control stick, while also contributing to ease of operation.
The Quad Sensor system of these models uses compact sensors that make it possible to pack compass, altitude/barometer, and temperature measurement capabilities, along with an accelerometer that keeps track of your step count, into a compact configuration. This makes it easy to keep tabs on the natural environment around you and to maintain logs of your activities for comprehensive flight mission support. A special G-SHOCK phone app simplifies configuration of watch settings, and also provides a Mission Function.
Designed for pros working in tough environments, this Bluetooth Quad Sensor GRAVITYMASTER takes advantage of carbon fiber’s exceptional strength-to-weight ratio to take timekeeping to entirely new heights. The bezel, made from carbon fiber inserts pressed between layers of resin, delivers outstanding toughness and practicality. And you can count on the exceptional functionality everyone expects from a G-SHOCK watch. Take to the skies with the GRAVITYMASTER GRB200-1B, boasting an innovative design for pilots who challenge the most extreme conditions high in the sky, presented in an all-black color scheme that stands for serious strength.
