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.

The octagon metal case on the GM-2100 rep is beautifully done - the brushed and polished sections alternate just like the retail. The ECB-10YP colourway looks great too.
Very solid feel, the octagon bezel has proper weight and none of the plasticky lightness you get on lower grade reps. The resin band matches the original color perfectly.
Love the compact size of the 2100 case. The metal bezel is a big upgrade over the plastic variants and this rep nails it. Arrived sealed in about 11 days.
Good 1:1 of the GM-2100. The backlight is the right blue tone, all functions work including world time and countdown. Slightly tight band clip on mine but it sorted itself out.
Q: Is the octagon bezel die-cast metal or stainless steel?
A: 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.
Q: Does this have the solar or Bluetooth features like the ECB-10?
A: 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.
Q: Can the resin band be swapped for an aftermarket strap?
A: Yes, the band uses the standard G-Shock 16mm adapter lug so most aftermarket G-Shock compatible straps will fit.
