Polar Street X

iPhone and AndroidPaid tier: Polar Fitness Program

Polar debuted Street X in March 2026 as an urban sports watch for people who train, commute and work in the city. Unusually for its price, it adds an LED flashlight with a red-light mode, a barometer and MIL-STD-810H shock testing to a bio-based plastic case. It keeps Polar's training and recovery tools but drops the ECG, SpO2 and maps of the Vantage line.

  • Headline: Polar: Smartwatch mode 10 d (US product page); support page: up to 10 days, 24/7 wrist HR and notifications on, always-on display off.
  • GPS: Polar US product page: Performance training mode 43 h (support page: up to 42 hours).
  • Polar's spec table lists GPS, Galileo, BeiDou and QZSS but no dual-frequency row, though its support page template mentions dual-frequency for the Performance mode. Eco training mode: up to 170 hours. No AOD figure.

The ring’s outer track is the headline claim; the inner two are the always-on and GPS figures as a share of it. An empty track means Polar does not publish that figure. Why the figures differ

Cleared health features

Polar cites no regulator clearance for a health feature on this model. Its heart-rate, sleep and blood-oxygen readings are wellness features.

A clearance says what a feature is allowed to claim, not that it replaces a doctor. Cleared versus wellness features

The two lists above are drawn from the maker’s own pages and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
