Swimming

NOTICE

The device is intended for surface swimming. Scuba diving with the device may damage the product and will void the warranty.

NOTE: The watch has wrist-based heart rate enabled for swim activities. The watch is also compatible with chest heart rate monitors, such as the HRM-Pro series accessories (Chest Heart Rate While Swimming). If both wrist-based heart rate and chest heart rate data are available, your watch uses the chest heart rate data.
