Casio’s G-Shock GA-2100K are inspired by nightclubs and music festivals, with a smoke-like finish on the transparent resin casing and strap. Plus, neon accents represent laser lighting often used in these settings. The GA-2100K-1A is gray with turquoise accents, the GA-2100K-2A is blue with orange accents, and the GA-2100K-5A is brown/orange with red accents.
The GA-2100 supports world time and offers tools like a stopwatch, countdown timer and multiple alarms. A double LED backlight can illuminate the hybrid watch’s analog and digital elements. Plus, there is a day of the week indicator, and the model is water resistant to 200 m. It remains to be seen when the Casio G-Shock GA-2100K watches will be released in other countries like the US, the Netherlands or Germany.
