G-SHOCK GA-2100SKE-7AER is a bracelet watch with a carbon-reinforced resin case and transparent housing designed for everyday and active use. With dimensions of 45.4 × 48.5 × 11.8 mm, this model combines the shock resistance typical of G-SHOCK with a compact, modern profile. The watch features mineral glass, a resin band with buckle, LED illumination and a battery life of approximately three years. It offers practical digital functions including world time, stopwatch, countdown timer, multiple alarms and an automatic calendar, all protected to 20 bar water resistance.
Advantages
The carbon-reinforced resin case improves impact resistance while keeping the weight low, and the transparent design provides a contemporary, versatile look. LED light and neo-display ensure legibility in low-light conditions, while the Hand Moving Function temporarily moves the analog hands for unobstructed view of digital readouts. Multiple timing functions, including a 1/100-sec stopwatch, 24-hour countdown timer and five daily alarms, support a range of everyday and sports tasks.
Suitable for
- Everyday wear and commuting

Replace the battery at a qualified service center when depletion is indicated to maintain water resistance and function.
