Polar Street X GPS Running Sports Watch
The Polar Street X is a GPS running sports watch built for modern hybrid training in the city and beyond. Designed for men and women, it tracks distance, pace, and performance with built-in GPS, route guidance, and back-to-start navigation, so you stay confident and in control on city runs and outdoor training alike. Built-in wrist heart rate manages your effort without a chest strap, and 170+ sport profiles cover running, strength, HIIT, cycling, and everyday training. It’s lightweight at 48 g, shock-resistant, and water resistant to 50 m for gym sessions, rain, and daily impact. Power keeps up with your week: up to 10 days of battery and 43 hours of GPS tracking between charges. Syncs with the Polar Flow app for full training analysis. Available in Black, Green, and White. Price: $249.90.
Our Take: The Polar Street X is a focused, do-it-all GPS watch for the hybrid athlete who runs the city streets one day and hits the gym the next. The essentials are all here and done well: built-in GPS with route guidance and back-to-start so you never have to wonder how to get home, a wrist heart rate sensor that handles effort and zone training without a chest strap, and 170+ sport profiles that cover running, strength, HIIT, and cycling. It’s genuinely light at 48 g, shrugs off rain and gym knocks with shock resistance and a 50 m water rating, and the battery is the quiet standout — up to 10 days of everyday use and 43 hours of GPS means most people charge it once a week, not every other day. Everything syncs to the free Polar Flow app for clean post-run analysis. At $249.90 it lands as an approachable, durable training watch rather than a maximalist multisport computer — and for runners who want reliable GPS, heart rate, and long battery without fuss, that focus is exactly the point. If you want the sharpest heart rate data for intervals, pair it with a Polar chest strap; otherwise the built-in sensor is ready to go out of the box.
