One review explicitly says brisk walks are logged automatically, suggesting useful basic auto-detection for everyday activity.
One comparison-heavy review says Garmin still has the stronger ecosystem, so the Street X competes more on simplicity and value than platform depth.

The strap setup looks solid, with easy swapping and a texture one reviewer specifically liked.
Band feedback is positive overall, with the Trail Loop and other stock options praised for comfort, durability, and activity-friendly design.
Battery life is one of the headline strengths, with claims and testing clustering around roughly a week-plus of heavy use or up to 10 days in smartwatch mode.
Battery life is strong by Apple Watch standards and often reaches two to three days, but several reviewers still find it short versus Garmin-style endurance watches.
Multiple reviews explicitly note that the Street X does not include SpO2 hardware, making blood-oxygen tracking a clear omission.
Blood oxygen support appears mixed across the review set: later coverage notes its return in the US, while some earlier long-term coverage still flags it as missing.
Bluetooth support is reviewed positively, especially for pairing cycling accessories like power meters and cadence sensors.

Charging is relatively easy to live with thanks to quick top-ups and even support for charging from an iPhone 15, though the watch still needs regular charging.
Charging speed is serviceable rather than class-leading; reviewers note useful top-ups, but also point out the Series 10 charges faster.
Coaching is built around training analysis, Training Load Pro, and a daily suggested workout rather than just passive data collection.
Training Load and related workout guidance add meaningful coaching value, helping users gauge effort and decide when to push harder.

Durability is one of the clearest strengths thanks to rugged construction, MIL-STD testing, and WR50 protection.

Fit is mixed: the low weight helps, but there is only one case size.
Fit is secure for many users, but the large 49mm case can feel challenging on smaller wrists.
The one detailed hands-on accuracy review says overall fitness-tracking accuracy was good across the sports it tested.
Fitness tracking is viewed as highly accurate overall, with especially strong comments around workout tracking and GPS-backed activity data.
GPS looked very good in the hands-on testing, though the same review still notes a few minor exceptions in certain route scenarios.
Most reviews praise GPS accuracy as excellent, though one in-depth test reported weaker results in a difficult dense-city scenario.
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.
Health tracking is generally regarded as strong and trustworthy, with positive remarks on broader health features and longitudinal monitoring.
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.
Heart-rate accuracy is one of the Ultra 2’s strongest areas, with multiple comparisons showing close agreement with chest straps.
LTE support is a useful standard feature that helps keep the Ultra 2 connected away from the phone.
Materials keep weight down but feel less premium, since the case leans heavily on plastic or composite parts and skips metal accents.
Material quality earns strong marks thanks to the titanium build, premium feel, and confidence-inspiring finish.

Music control support is solid, with Double Tap and on-watch controls helping with playback management.
Storage is strong for music and offline media, helped by 64GB capacity and support for downloadable content.
The proprietary Polar operating system is described as solid overall, though not especially refreshed or modernized.
watchOS is broadly praised for polish and feature depth, even if some reviewers still want deeper outdoor and athletic tools.
Outdoor visibility is mostly positive, though one reviewer warns it may not be ideal in the brightest sunlight.
Outdoor visibility is excellent, with the screen remaining easy to read in bright sun and other demanding conditions.
Recovery guidance is one of the stronger themes, with reviews highlighting workout-load feedback, Nightly Recharge, and prompts about whether training is on track.
Recovery insights are a notable weak spot, with several reviewers saying the Ultra 2 still lacks the deeper readiness and recovery analysis rivals offer.
One review positions the Street X around reliable tracking and dependable everyday use rather than feature overload.
Reliability feedback is positive overall, with reviewers describing the watch as dependable in day-to-day use and workouts.
Safety utility centers on the integrated flashlight, with repeated mentions of better visibility after dark and both white and red light modes.
Safety features are a standout, including siren, crash and fall detection, last-cell waypoint tools, and other emergency-focused functions.
Choice is limited here because the Street X is sold in only one case size.
Size choice is limited; multiple reviews call out the lack of alternatives beyond the single large 49mm case.

Sleep tracking is considered accurate by several reviewers, including comparisons that track closely with rival wearables.
Phone alerts for calls and messages are present, but reviews frame them as basic smartphone support rather than a headline feature.

Software smoothness is a weak point, with one reviewer explicitly calling the experience sluggish.

Siri is noticeably faster and more accurate on-device, though some reviews still mention minor voice-assistant quirks.
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 faces are well regarded, especially Modular Ultra and other Ultra-specific options that take advantage of the large screen.
Water resistance is consistently listed at WR50 or 50 meters, enough for common sports-watch use but not pitched as a dive tool.
