Open water swimming
When using the Open water swimming profile, the watch records your swim distance, time and pace, stroke rate for
freestyle as well as your route.
Freestyle is the only style that the open water swimming profile recognizes.
Pace and Distance: Your watch uses GPS to calculate pace and distance during your swim.
Stroke rate for freestyle: Your watch records your average and maximum stroke rates (how many strokes you take per
minute) for your session.
Route: Your route is recorded with GPS, and you can view it on a map after your swim in the Flow app and web service.
GPS does not work underwater, and because of this your route is filtered from GPS data acquired when your hand is out of
the water or very close to the water surface. External factors such as water conditions and satellite positions can affect the
accuracy of the GPS data, and as a result data from the same route can vary from day to day.
Measuring heart rate in water
Your watch automatically measures your heart rate from your wrist with the new Polar Precision Prime sensor fusion
technology, offering an easy and comfortable way to measure your heart rate while swimming. Although water may prevent
the wrist-based heart rate measurement from working optimally, the accuracy of Polar Precision Prime is sufficient to allow
you monitor your average heart rate and heart rate zones during your swimming sessions, get accurate calorie burn
readings, your Training Load from the session and the Training Benefit feedback based on your heart rate zones.
To ensure the best possible accuracy of your heart rate data, it’s important to wear the watch snugly on your wrist (even
more snugly than in other sports). See Training with wrist based heart rate for instructions on wearing your watch during
training.
Note that you can't use a Polar heart rate sensor with a chest strap with your watch when swimming because
Bluetooth doesn't work under water.
