It’s no secret that G-SHOCK is known as the industry leader for rock-solid timepieces built to withstand the harshest environments and elemental abuse, burly wrist fodder that neither rock nor mud nor ocean’s depths can stop. The new Quad Sensor GRAVITYMASTER GRB200, built for the skies with aviation professionals in mind, is a rough-and-tumble powerhouse ready to handle anything even the most hardcore pilot can throw at it. A carbon-fiber-reinforced resin case snugly houses all manner of technological wizardry, from compass to temperature gauge, accelerometer to altimeter/barometer. All of which can be synced to your smartphone via Bluetooth through the G-SHOCK Connected app for easy configuration and analysis. This isn’t so much a timepiece as it is a miniature command center for your wrist.
