Our take on the G-SHOCK GA-2100RL-1AER

The GA-2100RL-1AER is a slim analog-digital G-Shock in the CasiOak mold, with a carbon-core guard and bio-based resin case and band. At 16.9 mm thick and 72 g it wears far lighter than classic square or mudman G-Shocks while keeping 200 m water resistance and shock resistance. It adds world time across 29 time zones, a 1/1000-second stopwatch and five daily alarms. Owners like the stealthy black look and the light feel; the trade-offs are a mineral crystal, no solar charging and a two-year CR1220 battery.
