Our take on the Casio G-Shock Analog Digital Black Watch GA-2100-1A4

The GA-2100-1A4 is Casio's slim analog-digital G-Shock, nicknamed the CasiOak for its octagonal bezel. It pairs a carbon-core guard case with a resin strap, mineral glass, 200 m water resistance and a three-year battery. At 11.8 mm thick it wears far flatter than classic square G-Shocks, and it packs world time, five daily alarms, a 1/100-second stopwatch, countdown timer and an LED light. It suits people who want G-Shock toughness in a lighter, dressier case; the trade-off is a small analog dial and no solar or Bluetooth, which the pricier GA-B2100 adds.

Questions and answers

Is the GA-2100-1A4 worth it over a classic square G-Shock?
It offers a slimmer case and a more distinctive look, but the square models are easier to read. Choose it if fit and style matter more than a large digital display.

No. This model runs on a three-year battery and has no Bluetooth or solar. The GA-B2100 line adds both.

It is rated to 200 meters, so it is fine for swimming and snorkeling. Casio does not rate it for scuba diving.
What is in the box?
The watch comes with its original box and booklet, and Casio backs it with a one-year warranty.
How does it compare with the GA-B2100?
The GA-B2100 adds Bluetooth and solar charging in a similar case. This model is simpler and relies on a standard battery.
