Our take on the Casio G-Shock GA-2100-7AER rannekello

The Casio G-Shock GA-2100 is a slim analog-digital G-Shock with an octagonal carbon-resin case, shock resistance and 200-meter water resistance. At 11.8 mm thick and 51 g, it wears far lighter than classic square and chunky G-Shocks while keeping the full feature set: world time across 31 time zones, a 1/100-second stopwatch, a 24-hour countdown timer and alarms. It suits people who want G-Shock toughness in a watch that slips under a cuff, and it is the model behind the widely praised 'CasiOak' look. Owners like the light weight and legibility; the common complaints are the dim analog hands at night and the resin band's stiffness when new.

What reviewers say

Owners rate the GA-2100 highly for its slim, light build and the octagonal case that mimics far more expensive watches. Most praise the toughness and the full digital feature set at a modest outlay. Complaints center on night legibility and the basic resin strap.

What people mention
  • Size and weightPraisedOwners say it wears much slimmer and lighter than older G-Shocks and fits under a shirt cuff.
  • Night legibilityCriticisedReviewers complain the analog hands and markers lack lume and are hard to read in dim light.
  • BuildPraisedThe carbon-resin case and 200 m rating are trusted for swimming, gym and outdoor work.
  • BandMixedSome find the resin strap stiff and dust-attracting at first, though it softens with wear.
  • BatteryMixedThe roughly three-year battery is fine for many, but owners who wanted solar charging see it as a step back.

Questions and answers

Is the GA-2100 good for swimming?
Yes. It has 200-meter water resistance, which covers swimming, snorkeling and showering. It is not rated for scuba diving.
How does it compare with a classic square G-Shock?
It is slimmer and lighter than most square models and uses analog hands alongside the digital display. The square models are cheaper and have more legible digital-only screens.
Does it have solar charging or Bluetooth?
No. It runs on two SR726W batteries with about three years of life and has no app connectivity.
How big does it wear?
The case is 48.5 mm long, 45.4 mm wide and 11.8 mm thick at 51 g. Owners say it wears smaller than those figures suggest because of the slim profile.
Can I read it at night?
There is an LED light for the digital display, but the analog hands have no lume. Many owners find the hands hard to read in the dark.
What is in the box?
The watch with its resin band and a user manual. It ships in a G-Shock tin.
