The G-Shock GBM2100-1A is a metal-clad version of Casio's octagonal 2100 line, with a stainless steel bezel over a bio-based resin case and band. It pairs Bluetooth smartphone link through the CASIO WATCHES app with Tough Solar charging, so routine use needs no battery swaps. At 11.9 mm thick and 72 g it wears slimmer and lighter than most full-steel G-Shocks, and it keeps 200 m water resistance and shock resistance. It suits people who want a tough everyday watch that looks clean with a jacket, and it undercuts steel-cased Bluetooth G-Shocks on features per dollar while giving up sapphire crystal and a metal bracelet.

Owners of the 2100 series praise the octagonal metal look, light weight and solar-plus-Bluetooth combo. Common complaints center on the mineral crystal scratching and the resin strap feeling less premium than the bezel suggests.
The Casio G-Shock GBM2100-1A is a metal-clad version of the 2100 series with an octagonal bezel. The case and bezel combine bio-based resin and stainless steel, and the band is made of bio-based resin. The glass is mineral glass, and the watch is shock resistant and water resistant to 200 meters.
It is powered by Tough Solar charging and connects to a smartphone over Bluetooth® through the CASIO WATCHES app, which adjusts the time automatically. A double LED light illuminates the face and the digital display. A hand shift feature moves the hands out of the way so the digital display is unobstructed.
Functions include world time for 38 time zones, a 1/100-second stopwatch, a countdown timer, 5 daily alarms and a full auto-calendar to the year 2099.
