Is the GA-2100 good for everyday wear?

Yes. It is the slimmest G-Shock line, so it slides under a sleeve and stays light on the wrist. The resin strap and 200 m water resistance make it easy to live with.

Does it have Bluetooth or solar charging?

No. This model runs on a standard battery and has no Bluetooth or Tough Solar. Those features appear on higher G-Shock lines such as the GA-B2100.

How does it compare with the classic square G-Shock?

The GA-2100 is slimmer and lighter, with analog hands plus a digital window. The square models have a larger, easier-to-read digital display but a bulkier case.

Is the digital display easy to read?

It is small and uses a negative display, so it can be dim at a glance, and the hands sometimes cover it. The analog hands are clear.

Yes. It is rated to 200 meters, which covers swimming and snorkeling. Casio does not rate it for scuba diving.

The watch, a battery already fitted, and Casio's manual and warranty paperwork. No charging cable is needed.

Our take on the Casio G-Shock Black Green Analog Digital Watch GA-2100K-1AER

The Casio G-Shock GA-2100 is the slimmest G-Shock line, and this analog-digital model pairs a carbon core guard case with hands and a digital window on one dial. It carries the usual G-Shock toughness: shock resistance, 200-meter water resistance, world time, stopwatch, countdown timer and alarms. It suits people who want a rugged everyday watch without the bulk of older G-Shocks. Against pricier G-Shock models it gives up Bluetooth and solar charging, but it is lighter and thinner than the classic square and Mudman cases.
