CASIO G SHOCK GM-B2100BD-1A

CASIO G SHOCK GM-B2100BD-1A

Introducing a fully metal timepiece representing the continuous evolution of the 2100 line — inheriting the legacy of the very first G-SHOCK, the G-SHOCK DW-5000C.

This luxurious all-metal construction features a screw-lock case back, bezel, and band crafted from stainless steel. The refined yet streamlined design not only enhances sophistication but also helps protect the module from impact in the event of a drop.

Travel back in time with the iconic octagonal bezel and the dimpled band design inspired by the original 1983 model — now reimagined in full metal. A high-density mounting structure enables the analog-digital module to remain slim while delivering advanced functionality in a compact, comfortable fit.

Pair the watch with your smartphone via Bluetooth®. Simply connect to the dedicated app to ensure accurate timekeeping, so you never miss an important moment. Tough Solar power, a high-brightness LED light, and other convenient features make this model both stylish and highly practical.
