The Polar PACER S-L ultralight sports watch with next-generation GPS and optical heart rate sensor. A watch that provides athletes with an effective training tool. The resolution of the colour spectrum contributes to the increased accuracy of the watch by eliminating the factor of the colour of the skin. Thanks to the optimised GPS, the long-lasting battery lasts up to 35 hours with the GPS and pulse measuring modes on. In stand-by mode the batter life can last up to 100 hours with the GPS function on. The core of the watch is driven by a new and high-performance processor which is highlighted by the clear Always on the MIP display, which is readable under all conditions.
