Casio unveiled a new Gravitymaster wristwatch designed for aviation professionals this week.

The G-Shock Gravitymaster GRB200 is part of Casio’s “Master of G” collection and comes in a 54.1 mm x 18.3 mm case made of resin and is reinforced by a Carbon Core Guard Structure technology that strengthens the watch while keeping it lightweight by using carbon fiber.

Molded from resin that’s been injected with carbon fiber, the three-layer bezel is ultra-durable and has a semi-transparent top layer that reveals a woven carbon-fiber pattern below. There are three colorways, black (GRB200-1A), orange (GRB200-1A9), or blue (GRB200-1A2). The total weight of the watch including the resin strap is 80 grams.

Casio’s G-Shock Gravitymaster GRB200 features quad sensor technology that boasts a digital compass, altimeter/barometer, thermometer, and step counter. Further, the watch has Bluetooth connectivity which allows the watch to communicate with the G-Shock Connected app to simplify the configuration of watch settings and also allows you to maintain logs of your activities for comprehensive flight mission support.

When synced, the app records altitude points from the watch and GPS points from the phone. The Calorie Consumption Display calculates data from the step counter and takes altitude measurement into account. The Location Indicator records a current location on the app, and the watch acts as a backtracking device by pointing to the location with the second hand and showing the distance on the LCD display. The watch, of course, automatically adjusts the time through the Bluetooth connection. There’s also a phone finder function and the menu mode on the LCD display is customizable.

Interestingly, according to Casio, the new, unique button design with three large buttons set at different angles and shapes are arranged in a way to resemble a fighter jet control stick with powerful button guards to prevent operating errors while wearing gloves.

The G-Shock Gravitymaster GRB200 dial is protected by mineral glass that’s armored (or set below the plane of the bezel) to reduce the chance of scratches — or of the crystal being outright shattered. A stainless steel plate is secured via 4 screws to the caseback. The water-resistance is rated to 200 meters and the Gravitymaster is extremely resistant to both shock and vibration, which is helpful for pilots pulling serious gravitational forces.

Some of the other useful functions include double LED Lights, luminous hands/markers, World Time (38 Time Zones/38 Cities + UTC), Sunrise/Sunset Data, a 1/100th of a stopwatch (up to 24 hours), a countdown timer, 5 Multi-Function Alarms, 12/24 Hr Time Formats, and a full auto-calendar.

This Gravitymaster GRB200 watch is not solar-powered, instead it uses a low-cost and easily replaceable standard CR2025 battery that’s rated for approximately 2-years of use.
