6900 SERIES
GW6900U-1
A popular G-SHOCK that builds on the street-favored style of the DW-6900, updated with Multiband 6 for improved timekeeping accuracy. The GW-6900U keeps precise time by receiving radio-wave time signals from six stations worldwide, including two in Japan as well as stations in China, the United States, the United Kingdom, and Germany. Tough Solar powers the watch, even with light from indoor sources. A high-brightness full-auto LED backlight ensures clear readability in dark environments. The simple color scheme and clean, straightforward design offer a versatile look that suits any style.
