Product Details

Nicknamed the "CasiOak" by enthusiasts for its Royal Oak-inspired octagonal bezel, the GM-2100 wraps the G-Shock movement in a slim, sleek metal case that works equally well as a sport watch and a casual dress piece. The octagonal silhouette is immediately distinctive and the metal construction adds substantial wrist presence compared to resin-only G-Shocks. Practical functions are all present: world time across major cities, a fully automatic perpetual calendar, 12/24-hour mode, daily alarm, stopwatch, and LED illumination. At 49.3 x 44.4 x 11.8mm it wears comfortably on most wrists and looks equally sharp on male or female.

Frequently Asked Questions

Is the octagon bezel die-cast metal or stainless steel?

The bezel is constructed from stainless steel with mixed brushed and polished finishing to match the retail GM-2100 design, not die-cast zinc or plastic.

Does this have the solar or Bluetooth features like the ECB-10?

This rep replicates the external design of the ECB-10YP colourway. The internal features are standard G-Shock quartz functions - world time, stopwatch, and countdown - without Bluetooth or solar.
