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

The GA-2100 is Casio's slimmest analog-digital G-Shock, nicknamed the CasiOak for its octagonal bezel. It pairs a carbon core guard case with a resin strap, dual analog and digital displays, and 200 m water resistance. It suits people who want a tough everyday watch with a low profile and a streetwear look. Against other G-Shocks it is thinner and lighter, though it drops solar power and Bluetooth, which the higher-end models keep.

Questions and answers

Is the GA-2100 good for swimming?
Yes. It is rated to 20 ATM (200 m), so swimming and showering are fine. It is not a dive computer, so avoid deep diving.
How does it compare with the G-Shock DW-5600?
The GA-2100 is analog-digital with a slimmer octagonal case, while the DW-5600 is a square digital. Both are tough and water resistant; pick the GA-2100 for looks and the DW-5600 for a simpler, cheaper digital.
Does it have solar charging or Bluetooth?
No. It runs on a standard button battery and has no Bluetooth. Solar and Bluetooth appear on higher G-Shock lines such as the GAB2100.
What is the case size?
The case is about 45 mm across and roughly 11.8 mm thick, which is slim for a G-Shock. It weighs about 1.8 oz.
What functions does it include?
World time, stopwatch, countdown timer, alarms, a date display and an LED light. Time can be shown in 12- or 24-hour format.
Can I change the strap?
Yes, the resin strap is removable and uses standard G-Shock lugs, so aftermarket straps fit.
