Our take on the G-Shock GA-2100-1AER

The GA-2100-1AER is the black version of Casio's "CasiOak" line: an analog-digital G-Shock with an octagonal bezel and a slim carbon-core case. It packs world time, five alarms, a stopwatch, a countdown timer and LED lighting, with 200 m water resistance. It suits people who want a tough everyday watch that reads like a steel sports watch but weighs far less. Against the classic square G-Shocks it is slimmer and dressier; against steel analogs it is lighter and more shock-resistant, though its hands and markers are harder to read in low light.

Questions and answers

Is the GA-2100-1AER good for small wrists?
Yes. Its carbon-core case is one of the slimmest in the G-Shock range, so it sits flatter than the square models. The 48.5 mm width is still large, so try it on if you have a very small wrist.
How is it different from the GA-2100-1A1?
The 1AER is the standard black model with white hands and markers. The 1A1 is the all-black "stealth" version with dark hands and indices, which is harder to read.
Does it have solar charging or Bluetooth?
No. This model runs on a standard battery and has no Bluetooth. Solar and Bluetooth appear on other G-Shock lines, such as the GAB2100.
Is it really waterproof?
It is rated to 200 m, which covers swimming and snorkeling. Casio does not rate it for scuba diving.
What is in the box?
The watch, a Casio manual and the usual warranty paperwork. No extra strap or tool is included.
Where is the G-Shock GA-2100-1AER cheapest?
At Tempus Shop, for $95.00, 23% under what the other stores charge, as of our latest check.
Where can I buy the G-Shock GA-2100-1AER?
4 stores we checked sell it, including Tempus Shop, Footshop, First Class Watches, Amazon.
