The most versatile tracker. Visible or hidden! The Pulse O2 adapts to your style. During the day, you can wear the Pulse O2 in three different ways (wrist, belt/clothing, or in your pants or handbag). Use the wristband at night to monitor your sleep. Since the spring bars of the watch strap have a standard width (18 mm), you can even create your own personal strap.
