Our take on the CASIO G-Shock Analog-Digital 'Black' GA-B2100-1A1JF

The GA-B2100-1A1 is Casio's slim analog-digital G-Shock, the 'CasiOak' case shape with a black resin strap and black dial. It adds Bluetooth smartphone link and solar charging (Tough Solar) to the basic GA-2100, so it keeps time without a battery swap and syncs automatically. It is shock resistant and water resistant to 200 meters, with a carbon core guard case. It suits people who want a tough everyday watch with a low profile on the wrist; against the GA-2100 it costs more but brings solar and Bluetooth, while the digital-only squares are simpler and cheaper.

Questions and answers

How is the GA-B2100 different from the GA-2100?
The B2100 adds Tough Solar charging and Bluetooth smartphone link. The case shape and size are essentially the same.
Does it need a battery change?
No routine battery swap is needed. It charges from light through the dial, and the cell is meant to last many years.
Is it good for swimming?
Yes. It is water resistant to 200 meters, so it is fine for swimming and snorkeling, but not for diving.
Can I read it in the dark?
It has a double LED light for the dial and LCD. The negative digital display is still faint in daylight and dim light.
What does the Bluetooth link do?
It syncs time and settings with the Casio Watches app and can log step counts and reminders.
How does it fit on the wrist?
The case is slim for a G-Shock and sits close to the wrist. The resin strap suits most wrists.
