Casio G-Shock MASTER OF G AIR GRAVITYMASTER Black Carbon Fiber Insert Resin Band Watch GWRB1000-1A1 GWR-B1000-1A1

MASTER OF G GRAVITYMASTER

A model using the carbon material of the G-SHOCK GRAVITYMASTER series for pilots working under harsh conditions.

A carbon monocoque case integrates the case with the back cover to create a carbon core guard structure that protects the module from external impacts. This strengthens impact resistance and eliminates the need for button guards. Carbon material is used for the bezel and band, and titanium is used throughout for the push buttons and button pipes, etc. Use of a lot of high-performance materials strengthens the structure, reduces weight, and even prevents rust. It is also equipped with Triple G Resist. It also features a time adjustment system using Bluetooth® or standard radio waves to ensure time accuracy. GRAVITY MASTER helps you push the limits through the use of materials used in aircraft fuselages.
