Video Overview

Made with Real Carbon Fiber

The GRB200 G-SHOCK Gravitymaster uses real carbon fiber in what they call the Carbon Core Guard Structure. This technology offers world-renowned shock and vibration resistance. 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 (our favorite part, of course).

Inspired By Fighter Jets

Carbon fiber + fighter jets, it doesn't get much cooler. The three buttons on the side of this Gravitymaster are arranged in a way that makes them resemble a fighter jet control stick. Bonus, it also helps to make the watch easier to use.

  • Thermometer
  • Barometer / Altimeter
  • Digital Compass
  • Step Counter

Additionally, this G-SHOCK Gravitymaster has Bluetooth to connect to your phone through the G-SHOCK Connected app (iOS and Android). The app allows you to extend the capability of your watch even further.
