An elegant, solar-powered G-Shock that’s ready for any adventure under the sun

The process of selecting a watch can often feel like an exercise in weighing trade-offs. Go with a classic analog timepiece, and you’ll give up the stopwatch, timer, and alarms. Go with a digital that stores dozens of split times, and it might seem too casual for the office or nights out. And the options that link to your smartphone, while useful, almost always need to stay within reach of a charger. That’s why we love this new GA-B2100. It compresses all the functionality you’d want from a Bluetooth-connected digital watch into an elegantly simple analog silhouette with all of the toughness G-Shock is known for. Plus, it runs on a solar-power battery so you never have to worry about running out of time.


  • A classic G-Shock shape that blends the elegance of an analog dial with advanced digital features
  • Shock resistance, high-strength resin, and durable mineral-glass crystal means it’s ready for any adventure
  • Battery charges from solar energy and will run for seven months without exposure to light
  • Bluetooth connectivity keeps your time accurate, updating it when there are shifts in daylight savings or when you travel to another time zone
  • Stopwatch feature measures and stores elapsed time and split time in 1/100-second increments up to 60 minutes and 1-second increments up to 24 hours
  • Countdown feature operates in 1-second increments up to 24 hours
  • Allows you to set up to 5 daily alarms for managing tasks and reminders
  • 200-meter water resistance makes it safe for showering, swimming, or surfing
  • Super illuminator LED backlight with Afterglow enables you to read it clearly in low-light situations
  • Case and Bezel: Resin
  • Case Guard: Carbon
  • Band: Resin
  • Crystal: Mineral glass
