Casio G-Shock GM-B2100SD-1AER Men's Watch • Full Metal Stainless Steel • Tough Solar & Bluetooth

The Casio G-Shock GM-B2100SD-1AER is the refined full-metal edition of the legendary 2100 series, tracing its roots back to the very first G-SHOCK, the DW-5000C. The case, bezel and bracelet are crafted entirely from stainless steel, complemented by precisely manufactured resin buffer elements that form a shock-resistant structure. The octagonal bezel, featuring a hairline finish on its top surface and a mirror polish on the bevelled edges, gives the watch a minimalist yet premium appearance. The delicate dial with copper-toned vapour deposition, produced with the precision manufacturing technology of Yamagata Casio, adds an elegant finishing touch.

As an ana-digi combination model, the GM-B2100SD-1AER pairs classic analogue hands with a full range of digital functions. Tough Solar powers the watch via light energy, while Bluetooth connectivity to the Casio WATCHES app enables automatic time setting and world time across 38 time zones. Water-resistant to 20 bar, shock-resistant and fitted with mineral glass, this men's watch unites style with durability.
