Casio G-Shock GMC-B2100Y-1AER Men's Watch • Tough Solar • Bluetooth Mobile Link

The Casio G-Shock GMC-B2100Y-1AER is a full-metal chronograph in the iconic 2100 design, carrying forward the legacy of the very first G-Shock. The case and octagonal bezel are crafted from premium stainless steel, shaped through an elaborate process of forging, cutting and polishing, with a hairline finish on the top surfaces and a mirror polish on the bevels. The durable silicone band with a protective urethane layer and a vapour-deposited gunmetal finish complements the full-metal case with understated style. Thanks to high-density mounting, the analogue-digital combination module stays slim and ensures exceptional wearing comfort.

The GMC-B2100Y-1AER combines Tough Solar with Bluetooth connectivity: via the CASIO WATCHES app, the watch pairs wirelessly with your smartphone and sets the time automatically based on approximately 300 world time cities. Additional features include world time, stopwatch, countdown timer, daily alarm and a fully automatic calendar valid through 2099. The watch is shock-resistant and water-resistant to 200 m, a true companion for every demand.
