PRODUCT SAFETY GPSR
- Innovative Tough Solar: Efficient solar technology with a long operating life
- Perfect readability: Modern LED lighting and concise design
- Smart connectivity: Control your watch conveniently with your smartphone
The G-SHOCK GA-B2100 sets new standards by combining the iconic retro look of the first G-SHOCK models with the latest technology. With its distinctive octagonal design, the watch not only offers a visual highlight, but also a variety of practical functions for modern everyday life. The use of carbon resin in the case ensures maximum stability and light wearing comfort. The mineral glass reliably protects the display, while Neobrite ensures improved legibility even in poor lighting conditions.
A real highlight is the Tough Solar technology, which ensures virtually maintenance-free use, as the watch is charged by sunlight and achieves a runtime of up to 18 months without exposure to light. Added to this is the Smartphone Link for automatic time adjustment and the option to conveniently control your watch via an app.
The watch offers a variety of functions such as a precise stopwatch, a countdown timer and practical world time with 38 time zones, which also includes automatic daylight saving time adjustment. The LED illumination ensures a clear display at any time of day or night. With this G-Shock you not only have a functional timepiece, but also a real fashion statement.
