Water resistance of Polar products
Most Polar products can be worn when swimming. They are not, however, diving instruments. To maintain water
resistance, do not press the buttons of the device under water.
Polar devices with wrist-based heart rate measurement are suitable for swimming and bathing. They will collect your
activity data from your wrist movements also when swimming. In our tests, however, we found that the wrist-based heart
rate measurement doesn’t work optimally in water, so we cannot recommend wrist-based heart rate measurement for
swimming.
In the watch industry, water resistance is generally indicated as meters, which means the static water pressure of that
depth. Polar uses this same indication system. Water resistance of Polar products is tested according to International
Standard ISO 22810 or IEC60529. Every Polar device that has water resistance indication is tested before the delivery to
stand water pressure.
Polar products are divided into four different categories according to their water resistance. Check the back of your Polar
product for the water resistance category, and compare it to the chart below. Please note that these definitions do not
necessarily apply to products of other manufacturers.
When performing any underwater activity, the dynamic pressure generated by moving in water is greater than the static
pressure. This means that moving the product under water subjects it to a greater pressure than if the product were
stationary.
