Ambitious endurance athletes require precise GPS (multiband/multi-GNSS), reliable heart rate measurement, long battery life in training mode, VO2max/power zone analysis, barometric altimeter, robust housings and clear training/recovery metrics in sports watches to optimally support training efficiency and load control.

ISO 6425 for diving watches, shock tests, temperature tests, water resistance certificates, and tested altitude and pressure resistance for outdoor watches. These guarantee genuine durability.

Professional sports watches, thanks to modern multi-GNSS systems, typically achieve a GPS accuracy of about three to ten meters, depending on the environment and visibility. Altimeters operate barometrically and provide very accurate relative altitude changes, while absolute values ​​can fluctuate due to weather changes. Regular calibration ensures particularly reliable results.

For permanently activated sports functions, larger capacity batteries, energy-efficient processors and hybrid solutions (e.g. GPS via smartphone, intermittent GPS, power saving modes) are recommended; for particularly long activities, replaceable batteries (in simple GPS devices) or power bank compatibility are advantageous, while professional devices increasingly rely on optimized battery management software.
