The flagship model from the Gravitymaster line for pilots. The first ever G-Shock with a completely one-piece “monocoque” body made of carbon fiber. The case back, in the usual sense, is missing – the case is monolithic, and due to this, even greater impact resistance and reliability of the case are achieved. A completely new protective concept of the case – Carbon Core Guard is the presence of a special carbon body part that surrounds the watch module and protects them from any mechanical influences. Thanks to this, the GWR-B1000 is not only stronger than its counterparts, but also much lighter due to the use of carbon. Laminated carbon bezel consists of 52 separate layers, the button mechanism is isolated from the environment. The functionality of the series is also elite – solar power, multiband time synchronization, “pairing” with a smartphone via Bluetooth protocol [for auto-adjusting time and clock settings], 24-hour stopwatch with Fly Back function [quick zeroing], timer, one alarm clock, world time , well, of course, the proprietary “aviator” protection Triple G Resist [shock, centrifugal force and vibration]. Tough Movement [hard turn of the hands and their correction] and Smart Access [smart crown].

The most distinctive specs of GWR-B1000 *Editorial
— 200-meter water resistance (good for swimming but not for deep diving)
— Carbon Monocoque Case (single carbon Monocoque unit that protects the module from external shock and makes it possible to eliminate carbon guard parts from the buttons on the sides of the case)
— Rust-resistant structure (Buttons, button pipes, case internal fixing rings, and other metal parts exposed to outside air are made of strong, lightweight, and highly rust resistant titanium alloy)
— TRIPLE G RESIST (Shock resistant, Centrifugal force resistant, Vibration resistant)
— G-SHOCK Connected App (you may manage all watch settings through your phone)
— Mobile link (Wireless linking using Bluetooth(R)) (for time sync with your phone data)
— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)
— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)

Official Marketing Focus from Casio
From GRAVITYMASTER, the tough watch designed for the severe environments faced by pilots, comes a new timepiece that delivers an even higher level of toughness through the use of the same carbon and titanium materials found on modern aircraft.
A new shock resistant Carbon Core Guard structure integrates the case and back cover into a single carbon Monocoque unit that protects the module from external shock and makes it possible to eliminate carbon guard parts from the buttons on the sides of the case.
The use of carbon material for the bezel and band, and titanium alloy for buttons, button pipes, and components results in a watch that is both structurally tough, lightweight, and resistant to rust.
Automatic time adjustment is performed using either Bluetooth® or a time signal, which helps to ensure accurate timekeeping while flying on a mission.
