Casio G-SHOCK GA-2100-1AER “Black”
The Casio G-SHOCK GA-2100-1AER is one of the original models from the now-iconic 2100 Series, introduced in 2019. Its distinctive octagonal bezel takes inspiration from the first-generation DW-5000C while delivering a much slimmer analogue-digital profile. The black resin exterior is paired with a black dial, grey indices and hands, giving the watch a highly legible but understated monochromatic appearance.
Despite its slim 11.8 mm profile, the GA-2100 retains G-SHOCK’s durability through its Carbon Core Guard structure, which combines carbon fibre-reinforced resin with shock-resistant construction. It also features world time, five daily alarms, a 1/100-second stopwatch, 24-hour countdown timer, double LED illumination and 200-metre water resistance.
