About this timepiece

G-SHOCK's Full Metal GM-B2100 (ref. GM-B2100BD-1A) takes the octagonal 2100 shape all the way to stainless steel, and in black ion plating it is one of the most striking pieces in our showcase. The case, bezel and band are all steel with a screw lock back, and that full-metal build gives a sleek, minimalist look while shielding the module against impact if the watch is dropped. Thanks to high-density mounting, the analog-digital module stays slim, so the watch keeps a compact profile and a comfortable fit.

Light keeps it running through Tough Solar, with a power saving mode that blanks the display in the dark and a battery level indicator on the dial. Pair it with a smartphone over Bluetooth and the CASIO WATCHES app sets the time automatically, simplifies watch settings, offers about 300 world time cities and adds a reminder and phone finder. On the wrist you also get world time in 38 time zones, a 1/100-second stopwatch, a 60-minute timer, five daily alarms and a double LED light, all water resistant to 200 meters and closed by a one-touch three-fold clasp.

Timepiece History

G-SHOCK began with a developer's belief that a watch could be built not to break when dropped, and Project Team Tough was formed in 1981 to make it, working from Kikuo Ibe's concept. Over about two years the team built more than 200 prototypes around the "Triple 10" concept: 10-bar water resistance, surviving a 10-meter drop, and a 10-year battery. The DW-5000C that came out of that work debuted in 1983 with a hollow case that supports the core module at certain points, and G-SHOCK has kept building on that toughness idea ever since.

G-SHOCK launched the 2100 series in 2019 with the GA-2100, whose design concept is inherited from the DW-5000C and whose octagonal bezel carries a motif kept since the very first G-SHOCK. That first GA-2100 introduced the Carbon Core Guard structure, which uses carbon fiber-reinforced resin to strengthen the case from within. Casio presents the GM-B2100 as the 2100 line's first full-metal model, carrying the legacy of the DW-5000C into stainless steel.
