Our take on the Casio G-Shock Analog Digital Black GA-2100SU-1A

The GA-2100SU-1A is a blacked-out analog-digital G-Shock from the slim 'CasiOak' line, with a green-accented dial and a resin case and strap. It pairs analog hands with a small digital window and packs a stopwatch, countdown timer, world time, alarms, annual calendar and 200 m water resistance. At about 1.8 oz it wears far thinner and lighter than classic square or chunky G-Shocks, which is why people wear it daily. Reviewers rate it highly for toughness and looks; the common gripes are the dim LED light and the small digital display.

Owners rate it 4.6 out of 5 and mostly praise the slim fit, the stealthy black look and the toughness for the money. Complaints center on the dim light and the tiny digital readout.

What people mention
  • Size and weightPraisedOwners say it wears much slimmer and lighter than classic G-Shocks and fits under a sleeve.
  • LightCriticisedReviewers find the LED light dim and say it barely illuminates the analog hands.
  • DisplayMixedThe analog hands read clearly, but the small digital window is called hard to read.
  • BuildPraisedBuyers report it survives knocks, scratches and water without trouble.

Questions and answers

Is the GA-2100SU-1A good for swimming?
Yes. It is rated to 20 ATM (200 m), so swimming, snorkeling and showering are fine. Casio does not rate it for scuba diving.
How does it compare with the standard GA-2100?
It uses the same slim case and module. This SU version adds a green-accented dial and a different bezel finish; functions and size are the same.
Does it need a new battery?
Yes. It runs on a standard SR726W cell with no solar charging. Casio quotes roughly three years of battery life.
What is in the box?
The watch with its resin strap, a manual and the usual Casio warranty card. No charger or extra strap is included.
Is it too big for small wrists?
It is one of the smaller G-Shocks at about 45 mm across and 11.8 mm thick, so it suits most wrists. Very slim wrists may still find it chunky.
Can the hands be read in the dark?
The hands and hour markers have luminous paint, but the LED light is weak. Many owners use a phone or lamp in full darkness.
Where is the Casio G-Shock Analog Digital Black GA-2100SU-1A cheapest?
At KICKS CREW, for $127.53, as of our latest check.
