Altitude and temperature measurement: The Polar S625X/S725X calculates altitude by using the standard average altitude in certain air pressures according to the ISO 2533. The air pressure is measured and the temperature is compensated every second. The wrist unit displays altitudes between - 448 m - 7590 m or between - 1600 ft - 24900 ft with at least a 1 m / 3 ft resolution. The reference point’s adjustable altitude range is ± 610 m/ 2000 ft from the last measured value.
