Our take on the G-SHOCK GA-2100 Black

The G-Shock GA-2100 is Casio's slim analog-digital watch, often called the CasiOak for its octagonal bezel. It pairs a quartz movement with a carbon core guard case, shock resistance, 200m water resistance and a date display on a resin strap. At roughly 45mm across but under 12mm thick, it wears smaller than most G-Shocks and suits people who want a tough everyday watch without the bulk. Against pricier metal-cased rivals it gives up sapphire and premium finishing, but owners rate its toughness and light weight highly.

What reviewers say

Questions and answers

Is the GA-2100 good for small wrists?
Yes. It is about 45mm wide but under 12mm thick, so it sits flatter than most G-Shocks and suits wrists that find full-size models bulky.
Can you swim with it?
Yes. It is water resistant to 200m, which covers swimming and snorkeling. Casio does not rate it for scuba diving.
Does it have solar charging or Bluetooth?
No. This model runs on a standard battery and has no Bluetooth or solar. Those features appear on higher-end G-Shock models.
How does it compare with a classic square G-Shock?
The GA-2100 is slimmer and has analog hands plus a small digital display. The square models are thicker and fully digital, with a larger, easier-to-read screen.
What is in the box?
The watch on its resin strap, a manual and the usual Casio paperwork. No extra strap or tools are included.
