Comfortable Enough to Wear All Day. And All Night.
Sleep tracking only works if your fitness band stays on while you sleep-but many people remove theirs because it’s uncomfortable or needs frequent charging. The Astrum SB100N solves both with a soft, breathable fabric strap and a battery that delivers 30 to 45 days of use on a single charge, making it comfortable enough to wear around the clock.
Round-the-Clock Health Monitoring
An optical sensor continuously monitors your heart rate throughout the day and night. Measure your blood oxygen (SpO ) on demand, monitor stress levels through heart rate variability (HRV), and automatically track your sleep between 9:00 PM and 9:00 AM with detailed sleep stage analysis. The Da Halo app also includes AI-based menstrual cycle prediction.
Breathable Fabric. Just 25g.
The woven fabric strap offers enhanced breathability compared to silicone, helping reduce heat build-up and discomfort during extended wear. Weighing just 25g and measuring only 46 × 23 × 11mm, the SB100N is lightweight enough for everyday wear and comfortable enough to sleep in.
Smart Where It Counts
Stay connected with call and message notifications, including one-touch call rejection. Additional smart features include silent vibration alarms, hourly sedentary reminders, Do Not Disturb mode, a remote camera shutter, and Find My Bracelet.
