Polar’s rugged mid-range smartwatch delivers accurate tracking, extensive training tools and strong battery life, but a slow GPS lock, awkward interface and limited smart features weaken its value.
Polar’s Street X is aimed at runners and active commuters who want a robust watch without stepping up to the brand’s higher-end ranges, but its appeal is uneven. TechRadar’s review found a device that is strongest where it matters most for training: the GPS was accurate once locked, and the watch delivered a broad spread of health and exercise metrics. Yet that capability is undermined by a clumsy interface and a design that feels more functional than refined, leaving the impression of a capable product that has not been fully polished.
At $249.99 in the US, £219 in the UK and AU$429.99 in Australia, the Street X sits in the middle of the market rather than the premium end, placing it against watches from brands with more established smartwatch polish. TechRadar said it ships in three colourways and positions itself closer to Polar’s Pacer line than to its more expensive Vantage and Grit series. Other reviews have reached a similar conclusion on value: the hardware and feature set are respectable, but the pricing looks less compelling when compared with cheaper AMOLED rivals and more advanced running watches from Garmin and Coros.
The Street X’s design is built around durability rather than elegance. It uses a chunky, G-Shock-style case with five physical buttons, a 1.28-inch AMOLED display, Gorilla Glass protection and 50-metre water resistance, alongside MIL-STD-810H testing for resistance to heat, cold, vibration, dust and rain. That rugged construction may suit outdoor use, but TechRadar criticised the button layout and menu system as awkward, while Computer Bild also noted that the interface is less intuitive than it should be. The strap drew criticism too, although the watch was described as comfortable once fitted securely.
Where Polar is more convincing is in training and health tracking. The watch supports more than 170 sports and activities, includes Training Load Pro, adaptive running plans for 5K through marathon distances, continuous heart-rate monitoring, heart-rate variability, sleep tracking and skin-temperature readings. It also offers route guidance, breadcrumb navigation, elevation data, compass functions and a built-in LED flashlight, which other reviewers have highlighted as a first for Polar. Tom’s Guide and WearableBeat both pointed to the breadth of the fitness tools, though they also noted that some rivals offer more advanced mapping or dual-frequency positioning.
In testing, the main frustration was not accuracy but speed. TechRadar said the Street X often took more than a minute to acquire GPS lock, even though its location tracking then matched a Garmin benchmark closely. Heart-rate readings were said to line up with a dedicated chest-strap tracker, and battery life was described as solid at up to 10 days in smartwatch mode or 43 hours with GPS active. The watch also covers standard smart features such as notifications, weather, music control and phone-finding, but it stops short of offering the fuller app experience or message replies that many buyers now expect. For runners who value data and durability over finesse, it has clear strengths; for everyone else, the compromises are harder to ignore.
