Casio G-Shock G-Steel Bluetooth Watch GST-B100D-1AER

The Watch
Meet the latest G-Steel Bluetooth from Casio's iconic G-Shock line - a must-have timepiece for outdoor enthusiasts and tech-savvy adventurers alike. Tough yet refined, this watch delivers unmatched shock resistance along with a versatile set of everyday features. The robust case combines fine brushed steel with resin - two materials chosen specifically for their exceptional durability and resistance. The case measures 54 mm in diameter and 14 mm thick. Topped with a mineral crystal, it features a screw-back case, a screw-down crown, and four push buttons.

The Dial
The round dial is black and features applied double-color baton indexes: brushed silver on the angled inner bezel section and white on the upper section. The minute track is also white. Hours and minutes are read via two central luminous hands, providing excellent legibility in low-light conditions. The date is displayed through a window at 4 o'clock. Finally, the three sub-dials at 6, 9, and 12 o'clock indicate respectively the second time zone, the watch battery charge level indicator, and the day of the week with function mode.
