Casio G-Shock GA2100K
The GA 2100 earned the nickname CasiOak for an octagonal bezel that shares its design language with the Audemars Piguet Royal Oak. The GA2100K series takes that platform and gives it a nightlife treatment, with each colorway designed to capture the feel of laser strobes, fog machines, and late night energy on a dance floor.
Every model in the series combines translucent matte cases and bands with glossy piano black dials and neon accents in different colors. The smooth dial finish adds depth to the black, while the translucent materials give the bezels and straps a hazy, atmospheric texture. The varying tones and finishes across the lineup let each piece evoke a different shade of the same late night mood.
The foundation stays the same across the range. Carbon Core Guard construction keeps every model at 51 grams while maintaining 200 meters of water resistance. The analog digital display runs dual Super Illuminator LEDs, world time across 31 time zones, a 1/100 second stopwatch, five daily alarms, and a hand shift function that clears the analog hands for an unobstructed view of the digital readout.
