Train for a Month. Charge It Once.
Most fitness bands need charging every week-often right in the middle of your training routine. The Astrum SB100N delivers an impressive 30 to 45 days of battery life from a single 2-hour charge, so it stays on your wrist through workouts, recovery days, and every night of sleep tracking.
Built for Sweat
The soft silicone strap is designed for active lifestyles. It wipes dry in seconds, resists sweat and odours, and remains comfortable throughout the day. With a 3ATM (30m) water resistance rating, the SB100N is suitable for sweat, rain, handwashing, and warm showers. It is not designed for hot baths, saunas, or high-pressure water exposure.
Works with Strava
Automatically sync your runs, rides, and workouts to Strava without manually exporting activities or maintaining multiple training logs. The SB100N also syncs with Apple Health, making it easy to keep all your fitness data in one place.
121+ Sport Modes with GPS Route Tracking
Track more than 121 sports and activities, including running, cycling, gym workouts, yoga, swimming, and more. GPS route tracking uses your smartphone’s GPS to accurately record outdoor routes for runs, walks, and rides.
Recovery Tracking That Actually Runs
Monitor your health around the clock with 24/7 optical heart rate tracking, on-demand SpO measurement, and HRV-based stress monitoring. Automatic sleep tracking operates between 9:00 PM and 9:00 AM, analysing different sleep stages to help you better understand your recovery. Thanks to the long battery life, the watch stays powered long enough to capture every night.
