Product Details
Description
The Casio G-Shock GMC-B2100D-1AER is a men's watch from the ever-expanding 2100 line, combining the legacy of the first G-SHOCK from 1983 with cutting-edge technology. The fully stainless steel case — including bezel and bracelet — gives the watch an elegant yet robust presence. Fine resin shock-absorbing elements integrated between the bezel and case ensure the legendary impact resistance of the G-SHOCK series, even within this full metal design.
The distinctive octagonal case with screw-lock crown, the precisely finished dial featuring multiple hands in the 6-9-12 sub-dial layout, and the mirror-polished hands all reflect the highest standards of craftsmanship. Tough Solar powers the watch via light energy, while Bluetooth connectivity with the CASIO WATCHES app enables automatic time synchronisation. Water-resistant to 20 bar, with world time, stopwatch, countdown timer and alarm, the GMC-B2100D-1AER is as functional as it is stylish.
