G-Shock MRG-B2100D-1A
The G-Shock MRG-B2100D-1A takes the iconic 2100 shape and gives it the full-on premium treatment. Crafted from ultra-tough titanium with a Cobarion bezel that’s harder than steel, it’s as tough as it is refined. The dial’s got serious depth, inspired by traditional Japanese wood joinery. Solar-powered, Bluetooth-connected, and 200m water-resistant, it’s built for those who want hardcore durability without sacrificing style. This isn’t just a G-Shock, it’s the top of the food chain.
