Casio - GWG-B1000-1A4JF - 男士 - 2025年后

【GWG-B1000-1A4JF】
From G-SHOCK, which has pursued toughness since its birth in 1983, comes the MASTER OF G MUDMASTER FLAGSHIP model, achieving high durability and wearability with a robust exterior made of metal parts.

This GWG-B1000 model features a carbon core guard case structure, fusing a carbon fiber reinforced resin case*1 with metal materials produced using high-precision forging technology. In terms of functionality, it is equipped with radio-controlled solar power and a triple sensor, allowing it to acquire direction, barometric pressure/altitude, and temperature information. High visibility and time readability are ensured by double LED lights and sapphire glass.

It also features a location indicator function that points to the direction of locations recorded in the app or set in the app*2 by operating the watch.
