Casio G-Shock Master of G Gravitymaster GWR-B3000A-2AER

Designed for the most demanding aerial missions, it combines extreme durability, precision, and advanced technology. The Triple G Resist structure protects against shock, vibration, and centrifugal force, while the dual hollow case, with a suspended and cushioned central case, ensures robustness and a distinctive technical design.

The TOUGH MVT.2 Tough Solar movement guarantees high precision and automatically detects shocks and magnetic fields, correcting hand positions when necessary. The high-contrast micro-textured dial, sapphire crystal, and LED light ensure optimal readability.

Bluetooth® connectivity with the CASIO WATCHES app allows automatic time synchronization and access to the flight log. Direct access to UTC and the use of bio-based resin for the central case and strap complete the features.
