Polar 910117335 GPS Multisport Watch with Precision Prime Heart Rate, Barometer, and 35h Training Battery – Black

Built for athletes who demand precision without compromise, the Polar 910117335 stands apart from typical multisport watches by pairing an aerospace aluminum case with Polar’s proprietary Precision Prime™ optical heart rate sensor. Unlike many competitors that rely on a single satellite system, this watch locks onto GPS, GLONASS, Galileo, and QZSS simultaneously for faster, more accurate tracking in challenging environments. Add a barometer for real-time altitude and running power, and you have a training tool that adapts to mountains, trails, and city streets alike.

• Polar Precision Prime™ optical heart rate with 10 LEDs for reliable wrist-based readings

In daily use

From sunrise intervals to weekend long runs, the Polar 910117335 keeps pace without constant charging.
