How does the tracker monitor heart rate and blood oxygen around the clock?

The device uses optical sensors to collect continuous heart rate and SpO2 estimates throughout the day. Data is visible on the watch in real time and stored in the companion app so you can review trends and spot changes over time.

• 24/7 optical heart rate sensing with on-watch display.
• Automated blood oxygen (SpO2) readings across the day.
• Historical charts in the mobile app for trend analysis.
• Alerts and personalized wellness suggestions based on readings.

What workout and outdoor features help during exercise?

This tracker supports more than 24 sports modes to log steps, distance, calories and exercise heart rate. It’s IP68-rated for water resistance, so it handles sweat, splashes and swimming sessions, while activity-specific metrics give better feedback for each workout type.

• 24+ built-in sport modes with live metrics.
• Step counter, distance, and calorie estimates for daily activity.
• IP68 waterproof rating suitable for swimming and rain.

How do smart features and daily tools simplify life?

Beyond health tracking, the watch delivers call and message notifications, weather updates, music control, and remote camera shutter so you can manage essentials from your wrist. Helpful reminders—like alarms, sedentary alerts and female health tracking—make it a practical everyday companion.

• Music control and remote shutter for hands-free use.
• Breathing exercises, alarms, and sedentary reminders.
