G-SHOCK GRAVITYMASTER BLACK/CARBON FIBER MENS WATCH – GWR-B1000-1A1DR

FEATURES
GRAVITYMASTER
Carbon Core Guard structure

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.
Materials, structure, and functions. Everything about this model contributes to the creation of a new GRAVITYMASTER model with a new level of toughness that can stand up to new challenges.

Designed to be the toughest, lightest model in the GRAVITYMASTER Series.

New shock resistant construction
Carbon Core Guard
A new shock resistant Carbon Core Guard integrates the case and back cover into a monocoque case that protects the module. An external structure that capitalizes on the high strength and lightweight characteristics of the material used dramatically improves toughness while also enabling a weight of only 72 grams, making this the lightest model in the GRAVITYMASTER Series.

• Carbon Fiber Bezel
• Carbon Monocoque Case
• Guard-less Buttons

Lightweight, resists rust.
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.

Stands up to rough use
Carbon fiber insert band
Carbon fiber of outstanding tensile strength is molded into urethane resin for a band that resists breaking.

Strength and accuracy to support flight missions.
