  • Our take on the Casio G-Shock GBM2100-1A

    The Casio G-Shock GBM2100-1A is a solar-powered, Bluetooth-connected analog-digital watch in the slim 'CasiOak' case style. It pairs with the Casio Watches app for automatic timekeeping, world time, alarms, and a phone finder, and its Tough Solar cell charges from light. The resin case and strap keep it light at 2.5 oz, and 200m water resistance and shock resistance make it a durable daily wear. Compared with the standard GA-2100, it adds solar charging and Bluetooth sync, which are its main advantages; compared with a smartwatch, it offers far longer runtime but fewer smart features.

    Questions and answers

    Is the GBM2100-1A worth it over the standard GA-2100?
    Yes, if you value solar charging and Bluetooth time sync. The GA-2100 is cheaper but lacks these features and requires battery changes.
    How does the solar charging work?
    The dial collects light to charge an internal battery. Regular exposure to daylight keeps it running, and a full charge lasts months in the dark.
    Can I use it without the app?
    Yes, the watch works standalone, but you need the app to set world time, alarms, and other settings easily, and to sync time automatically.
    Is it suitable for swimming?
    Yes, it is water resistant to 200 meters, so it is fine for swimming and snorkeling, but not for diving.
    What is included in the box?
    The watch, a user manual, and warranty information are included. No charging cable is needed.
    How does it compare to a smartwatch?
    It offers much longer battery life and durability but lacks smart features like notifications or fitness tracking. It is better for those who want a reliable watch with basic connectivity.
