Polar Street X Review 2026: An Affordable Sports Watch With a Built-In Flashlight
What to Look For
The Polar Street X, launched 25 March 2026, is Polar’s attempt at an affordable, everyday sports watch — sitting below the Vantage and Grit X ranges on price while keeping Polar’s core training and recovery metrics. If you want Polar’s Precision Prime heart rate tracking and recovery insight without the flagship price tag, this is the model to look at.
Key Features to Consider
- 1.28″ AMOLED touchscreen — protected by Gorilla Glass 3, bright enough for outdoor training sessions and easy to read at a glance mid-session.
- Built-in GPS with compass and barometer — includes route guidance and back-to-start navigation, useful for open-water swim exits and unfamiliar run routes.
- 170+ sport profiles — broad enough to cover swim, bike and run training alongside gym and hybrid workouts.
- Precision Prime optical heart rate + nightly skin temperature — Polar’s established recovery-tracking approach, carried down from the more expensive Vantage line.
- Integrated LED flashlight — switchable between white and red light, a genuinely useful feature for early-morning or after-dark training that most GPS watches don’t offer.
- Battery life — up to 10 days in watch mode, up to 43 hours with continuous GPS tracking.
Our Verdict
Polar Street X — £219 UK
Independent testing from DC Rainmaker and Tom’s Guide both landed in a similar place: solid fundamentals for the price, but not a category leader against Garmin’s entry-level Forerunner range on GPS accuracy or app polish. Where it does stand out is the built-in flashlight and Polar’s recovery metrics, which are usually locked behind a much higher price point. If you’re already in the Polar Flow ecosystem and want a lower-cost multisport watch for training rather than racing, it’s a sensible pick. If you rely on advanced running power or offline maps, the Vantage or Grit X ranges remain the better fit.

Buying Tips
- If you already own a Polar Vantage or Grit X, the Street X is a step down in features, not an upgrade — it’s aimed at new Polar customers, not existing ones.
- Check your local retailer for launch bundle pricing — it’s positioned to undercut Garmin’s equivalent entry-level GPS watches.
- The flashlight is genuinely handy for early starts, but it will draw down the battery faster than the quoted 10-day figure if used heavily.
Care and Maintenance
Rinse the strap and sensor housing with fresh water after open-water swims or salty sessions to avoid skin irritation and sensor grime build-up. Keep the watch charged above 20% before long trips or race weekends, and update the firmware regularly through the Polar Flow app for the latest feature and bug-fix releases.
