Our take on the Casio GA-B2100 G-Shock Series Wristwatch w/ Bluetooth, Solar

The GA-B2100 is Casio's slimmed-down G-Shock 'CasiOak' with two upgrades over the original GA-2100: Tough Solar charging and Bluetooth pairing with the Casio Watches app. It keeps the octagonal bezel, carbon core guard case and analog-digital dial that made the line popular, in a case roughly 11.8 mm thick and about 51 g. It suits people who want a tough everyday watch with phone-assisted timekeeping and no battery swaps. Against the GA-2100 it adds solar and Bluetooth; against pricier G-Shock models it gives up metal construction and a sapphire crystal.

High-quality product from Japan.

Questions and answers

How is the GA-B2100 different from the GA-2100?
It adds Tough Solar charging and Bluetooth with the Casio Watches app. The case shape, dial layout and carbon core guard carry over.
Does it need a battery change?
It runs on a rechargeable cell charged by light through the dial. In normal use it should go years without a replacement, though a dark drawer drains it.
What does the Bluetooth connection do?
It syncs time and settings with the phone and supports a phone finder and step tracking. It does not add notifications or GPS.
Is it good for swimming?
Yes. It is rated to 200 m water resistance, so swimming and snorkeling are fine. Avoid pressing buttons underwater.
How does it compare with metal G-Shock models?
It is lighter and less expensive in build, with resin and a mineral crystal instead of steel and sapphire. It keeps the same shock and water ratings.
What is in the box?
The watch, a Casio manual and warranty paperwork. No charging cable is needed since it charges from light.
