The GBA-900UU-3A projects a bold, athletic identity, blending robust build and modern functionality in an urban-ready silhouette. With a rugged resin case and band, it offers shock resistance and a 200 metres water-resistance rating, a combination that ensures it stands up to daily wear, outdoor adventures, or training sessions. 

Smart-Enabled & Fitness-Focused
This model goes beyond basic timekeeping: it syncs with your smartphone via Bluetooth, allowing access to data like distance, pace, calories burned, lap times and more useful for runners, athletes, or anyone tracking their workouts. Typical functions include a stopwatch, timer, auto-calendar, multiple alarms, and world-time support — making it versatile both for sport and travel.

Designed for Visibility, Comfort & Everyday Use
The case measures roughly 51.3 × 48.9 × 16.6mm, and the watch weighs about 61g, solid but wearable. A dual-LED illumination ensures readability in low light, whether you’re out on a late-night run or exploring the city after dark.
