  • Our take on the Casio G-Shock GM-B2100BD-1AER

    The GM-B2100BD is the full-metal version of Casio's octagonal 'CasiOak' G-Shock. It keeps the slim analog-digital layout and 200m water resistance but swaps the resin case for stainless steel, adds Bluetooth phone pairing and a solar charging system. That puts it against steel sports watches and other metal G-Shocks: it is tougher and more feature-packed than a plain dress watch, but heavier and less refined than a dedicated mechanical. It suits people who want G-Shock durability in a watch that looks dressier.

    Questions and answers

    Is the GM-B2100BD worth it over the resin GA-2100?
    If you want a metal look and solar charging, yes. The resin GA-2100 is lighter and cheaper but has no solar or Bluetooth.
    Can you swim with it?
    Yes. It is rated 200m water resistant, so swimming and snorkeling are fine. Casio does not rate it for scuba diving.
    Does it need a battery change?
    No, it charges from light through a solar cell. Keep it in light now and then; a dark drawer for months can drain it.
    What does the Bluetooth app do?
    It syncs time from your phone, sets world time and alarms, and tracks step count. The watch works without it.
    How big is it on the wrist?
    The case is about 44mm across but slim, so it wears smaller than most G-Shocks. The steel bracelet adds weight.
    What is in the box?
    The watch, a steel bracelet, and Casio's manual and warranty card. No charging cable is needed.
    Where is the Casio G-Shock GM-B2100BD-1AER cheapest?
