Our take on the Casio G-Shock Analog Digital Smartphone Link Black Dial Resin Solar GA-B2100BEG-1A 200M Men's Watch

The GA-B2100 is Casio's slim octagonal G-Shock with Tough Solar charging and Bluetooth phone link. It pairs with the Casio Watches app for automatic time sync, easy alarm and timer setup, and a phone finder, while the solar cell keeps it running without battery swaps. At 11.9 mm thick with Carbon Core Guard construction, it wears lighter and flatter than older 2100 models and most chunky G-Shocks. Reviewers rate it as a tough, low-maintenance daily watch; the main complaints are the small negative LCD and the fiddly analog hands against busy dials.

Questions and answers

Is the GA-B2100 worth it over the standard GA-2100?
Yes if you want solar charging and Bluetooth time sync. The standard GA-2100 is cheaper but runs on a battery and has no phone link.
Does it need a battery change?
No. Tough Solar charges from light through the dial, so there is no regular battery swap under normal use.
Can I read it in the dark?
Yes. It has an LED light and Neobrite-coated hands, though the digital display stays small.
Is it good for swimming?
Yes. It is rated to 200 m water resistance, suitable for swimming and snorkeling, but not for scuba diving.
What does the Bluetooth link do?
It syncs time automatically, lets you set alarms and timers from the phone, and helps find your phone.
How big is it on the wrist?
The case is 11.9 mm thick with the octagonal 2100 shape, so it sits flatter than most G-Shocks.
