Battery life is widely praised, with most reviews citing around nine days and some testers stretching well beyond a week.
Multiple reviews explicitly note that the Street X does not include SpO2 hardware, making blood-oxygen tracking a clear omission.
Pulse Ox is present and generally viewed positively, with one reviewer calling the SpO2 readings spot-on.
Bluetooth support is consistently mentioned for sensor links, heart-rate broadcasting, and phone connectivity.
Brightness lands in the solid-not-exceptional range: around 1,000 nits and generally good enough, but not class-leading.
One reviewer said the screen can be hard to read in very bright conditions, even at maximum brightness.
Build quality gets favorable comments for its rugged, protective construction, even if it is not luxurious.
The move from a plastic case to a metal case is presented as a quality upgrade.

The new physical buttons are one of the most praised upgrades, especially for workouts and easier navigation.
Calorie data is available, but one review said calories burned ran slightly off compared with another watch.
Charging is convenient for existing Polar owners because it uses the same USB-C-based charger as newer siblings.
Charging is improved by the standard Garmin cable or simple magnetic setup, and reviewers call the new approach more convenient.
Charging speed is good, with reviewers reporting roughly a full charge in about an hour.
Coaching is built around training analysis, Training Load Pro, and a daily suggested workout rather than just passive data collection.
Garmin Coach and structured workouts are widely praised for offering guided plans and flexible goal-based training.
Comfort is a recurring strength because the watch stays light enough for all-day wear despite its rugged look.

Display quality is a consistent plus, with the AMOLED screen repeatedly described as nice, crisp, sharp, and easy to read.
The hidden monochrome display earns praise for clarity and contrast, though it remains intentionally simple rather than rich or colorful.
Durability is one of the clearest strengths thanks to rugged construction, MIL-STD testing, and WR50 protection.
Durability impressions are mixed, with Gorilla Glass noted positively but aluminum scratch resistance called out as a weakness.
ECG is repeatedly listed as missing, so buyers wanting wrist-based electrocardiogram features will need a different watch.
Reviews explicitly note that the Lily 2 Active does not include ECG support.
Fit is mixed: the low weight helps, but there is only one case size.
The compact size and lightweight build earn strong praise for smaller wrists and all-day wear.
The one detailed hands-on accuracy review says overall fitness-tracking accuracy was good across the sports it tested.
General fitness tracking is reviewed very positively, with performance described as accurate and comparable to pricier Garmin models.
GPS looked very good in the hands-on testing, though the same review still notes a few minor exceptions in certain route scenarios.
GPS is a standout strength, with multiple reviews calling it accurate, fast to connect, and very close to higher-end Garmin devices.
Health readouts seem directionally useful, but the hands-on review warns not to treat the watch's sleep analysis as something to fully rely on.
Heart-rate performance is generally described as good, with one detailed test review finding it accurate and other reviews calling the sensor pretty good or more consistent during workouts.
Multiple reviews say heart-rate tracking was very solid or spot-on, with only minor lag during quick changes in effort.
Materials keep weight down but feel less premium, since the case leans heavily on plastic or composite parts and skips metal accents.
Materials get mixed feedback: Gorilla Glass and aluminum are appreciated, but one reviewer still viewed the aluminum as easier to scratch than pricier materials.
Menu navigation appears straightforward enough for scrolling through widgets and daily/training details without much friction.
Menus and widget navigation are generally viewed as straightforward, with swipes and buttons making the watch easier to move around.
Music controls are included, but only as part of the basic smart-feature bundle.
Phone-based music controls work well for basic playback tasks like volume and track skipping.
Multiple reviews explicitly say there is no onboard music storage, so you still need your phone for music.
The proprietary Polar operating system is described as solid overall, though not especially refreshed or modernized.
Outdoor visibility is mostly positive, though one reviewer warns it may not be ideal in the brightest sunlight.
One review specifically said the screen stayed readable outdoors, even in direct sunlight.
Pairing is described as easy and dependable for phones and supported external sensors.
Recovery guidance is one of the stronger themes, with reviews highlighting workout-load feedback, Nightly Recharge, and prompts about whether training is on track.
HRV, Body Battery, Training Readiness, and related guidance give useful signals about recovery and when to push or rest.
One review positions the Street X around reliable tracking and dependable everyday use rather than feature overload.
One reviewer explicitly described the watch as very reliable during GPS use.
Safety utility centers on the integrated flashlight, with repeated mentions of better visibility after dark and both white and red light modes.
Incident detection, fall alerts, and emergency contact sharing are repeatedly mentioned as reassuring safety features.
Choice is limited here because the Street X is sold in only one case size.
Sleep tracking can reflect better and worse nights, but one reviewer still calls Polar's sleep-stage performance mediocre compared with the best sleep-focused devices.

Value is a major selling point across nearly every review, which repeatedly calls the Street X affordable, competitive, and one of the best-value options in its class.
Value is mixed but mostly positive: several reviews say the added GPS and upgrades justify the price, while others think rivals offer more for similar money.
Watch-face selection is described as numerous, giving users a fair amount of choice even if it is not treated as a signature feature.
Watch face options get mixed feedback: the designs suit the look of the watch, but several reviewers wanted more variety or more color.
Water resistance is consistently listed at WR50 or 50 meters, enough for common sports-watch use but not pitched as a dive tool.
One review states the watch is water resistant to 5 ATM.
