Description
CASIO G-SHOCK GA-2100K-5AER is a men’s watch from the G-Shock series, where the iconic “CasiOak” has transformed into an object with its own atmosphere. The same K collection — a night city, laser light through fog, the pulse of electronic music you feel before you hear it.
The semi-transparent bezel and strap made from matte warm amber-brown resin — not the usual black resin, but a new material with a cloudy, hazy texture that recalls the atmosphere of a club hall at the hottest moment of the night. Inside, this transparency reveals the Carbon Core Guard construction — and that is no longer just a detail, it’s a show. The glossy black dial with a new flat surface absorbs light like a dark stage before a performance begins, while bright neon-red accents on the hands and indices flare against this backdrop like a laser beam cutting through club smoke. The warm brown frame and burning red — a combination that recalls a night party at the height of summer. The dual LED Super Illuminator backlight lights up both the analog and digital sections — one press, any night.
The shock-resistant Carbon Core Guard construction, 200-meter water resistance, 5 alarms, a 1/100-second stopwatch, a countdown timer up to 24 hours, and world time for 31 time zones. The 48.5 × 45.4 × 11.8 mm case weighs just 51 g. The battery lasts approximately 3 years.
CASIO G-SHOCK GA-2100K-5AER — for those who leave an atmosphere behind them.
