One comparison-heavy review says Garmin still has the stronger ecosystem, so the Street X competes more on simplicity and value than platform depth.
Garmin’s broader golf ecosystem was praised for keeping practice, round, and device data inside one connected setup.
The strap setup looks solid, with easy swapping and a texture one reviewer specifically liked.
The integrated strap feels comfortable on the wrist, but several reviewers disliked that it does not lay flat when removed.
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 was one of the strongest themes, with reviewers consistently reporting multi-round endurance and far longer runtime than an Apple Watch.
Multiple reviews explicitly note that the Street X does not include SpO2 hardware, making blood-oxygen tracking a clear omission.
Pulse ox and blood-oxygen tracking are included and were cited as part of the S70’s broader health monitoring suite.
Bluetooth audio support is present for music listening, with reviewers noting headphone pairing and Bluetooth music use.
Brightness lands in the solid-not-exceptional range: around 1,000 nits and generally good enough, but not class-leading.

Build quality gets favorable comments for its rugged, protective construction, even if it is not luxurious.
Reviewers described the watch as well built, with a premium feel that matches its flagship positioning.
Button controls are a strength, with large, textured, easy-grip hardware repeatedly called out.
The three-button layout was generally seen as easy to learn and helpful for navigating golf functions.
Call support is limited: reviewers noted caller alerts and some answer or reject options, but not full on-watch calling.
Charging is convenient for existing Polar owners because it uses the same USB-C-based charger as newer siblings.
Charging drew frequent criticism because of the proprietary cable, face-down setup, and lack of an included adapter in some boxes.
At least one reviewer said the watch tops up quickly enough that short charging windows are practical.
Coaching is built around training analysis, Training Load Pro, and a daily suggested workout rather than just passive data collection.
Virtual Caddie, PlaysLike tools, and tempo coaching were major selling points, though the tempo feature was not equally useful for every reviewer.
Comfort is a recurring strength because the watch stays light enough for all-day wear despite its rugged look.
Comfort was a consistent strength, with reviewers saying the watch wears lightly and remains comfortable for all-day and overnight use.
The companion app is a recurring complaint, described as outdated and not great for quick health and fitness overviews.
Garmin Golf was described as one of the better golf apps for stats, post-round review, and tying watch data together.
Garmin Pay is built in, but support can be uneven depending on bank compatibility and region.
The watch works with both iPhone and Android, though some reviewers noted better notification control on Android.
Customization is decent through quick-release straps, swappable bands, and configurable widgets or complications.
Reviewers liked the ability to change watch faces, colors, data fields, and golf display settings.
Display quality is a consistent plus, with the AMOLED screen repeatedly described as nice, crisp, sharp, and easy to read.
The AMOLED display was one of the product’s standout strengths, praised for crisp detail, color, clarity, and a premium look.
Durability is one of the clearest strengths thanks to rugged construction, MIL-STD testing, and WR50 protection.
Evidence pointed to solid durability, including a scratch-proof lens and confidence for regular golf use.
ECG is repeatedly listed as missing, so buyers wanting wrist-based electrocardiogram features will need a different watch.
Fit is mixed: the low weight helps, but there is only one case size.
Fit was widely praised, and the added 42mm option helped make the watch more comfortable for smaller wrists.
The one detailed hands-on accuracy review says overall fitness-tracking accuracy was good across the sports it tested.
At least one reviewer explicitly said the S70’s fitness and sensor data are as accurate as expected from Garmin.
GPS looked very good in the hands-on testing, though the same review still notes a few minor exceptions in certain route scenarios.
Reviewers repeatedly praised fast GPS lock and very accurate on-course yardages, with some comparisons landing within about a yard.
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 was generally viewed as trustworthy, with reviewers calling the readings accurate in typical Garmin fashion.
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 tracking was included in the praised sensor package, with one reviewer explicitly describing Garmin-level accuracy.
Materials keep weight down but feel less premium, since the case leans heavily on plastic or composite parts and skips metal accents.
Ceramic bezels and quality strap materials gave the watch a more premium feel than cheaper golf models.
Menu navigation appears straightforward enough for scrolling through widgets and daily/training details without much friction.
Navigation was mostly described as intuitive once learned, though one reviewer felt the interface had a steeper learning curve.
Music controls are included, but only as part of the basic smart-feature bundle.
Music controls are available, but some reviewers found them less immediate than on an Apple Watch.
Reviewers confirmed on-watch music storage and offline playlist support from services like Spotify and Amazon Music.
The proprietary Polar operating system is described as solid overall, though not especially refreshed or modernized.
The software experience is capable and feature rich, but several reviewers still preferred mainstream smartwatches for daily smartwatch polish.
Outdoor visibility is mostly positive, though one reviewer warns it may not be ideal in the brightest sunlight.
Outdoor readability was a clear strength, with reviewers repeatedly saying the screen stays visible in bright sunshine.
Initial phone pairing was described as simple and straightforward in setup.
Recovery guidance is one of the stronger themes, with reviews highlighting workout-load feedback, Nightly Recharge, and prompts about whether training is on track.
Body Battery, HRV, and readiness-style insights added useful recovery context, though not every reviewer found them equally valuable.
One review positions the Street X around reliable tracking and dependable everyday use rather than feature overload.
Core performance was strong, but one reviewer did flag missed shot detections as a reliability blemish.
Safety utility centers on the integrated flashlight, with repeated mentions of better visibility after dark and both white and red light modes.
Choice is limited here because the Street X is sold in only one case size.
The new two-size lineup was seen as a meaningful improvement, especially for golfers who found earlier Garmin golf watches too large.
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.
Sleep tracking was viewed positively overall, with reviewers calling it strong and engaging enough to check regularly.
Phone alerts for calls and messages are present, but reviews frame them as basic smartphone support rather than a headline feature.
Notifications are available and customizable to a degree, but multiple reviewers said they can feel distracting or limited versus Apple Watch behavior.
Smart features cover the essentials, but the watch is still presented as fitness-first and somewhat limited on the broader smartwatch side.
Beyond golf, reviewers consistently saw the S70 as a full-featured smartwatch with strong everyday usefulness.
Software smoothness is a weak point, with one reviewer explicitly calling the experience sluggish.
Software smoothness was mixed: some reviewers said the watch is enjoyable to use, while others found parts of the interface annoyingly clunky.
Stress tracking was repeatedly called useful, and at least two reviewers said the readings felt surprisingly accurate.
Styling is widely seen as a positive if you like the rugged G-Shock or Instinct-like look, though it is bulkier than Polar's usual aesthetic.
The S70’s styling was widely praised as modern, premium, and suitable away from the course.
Support for services like Spotify and Apple Music added useful flexibility beyond Garmin’s own apps.
Touch response was generally good, but several reviewers said on-course map interaction can feel fiddly compared with the best smartwatches.
User-interface feedback is mixed: it is simple and easy to understand, but several reviews still describe it as dated or not ideal for quick overviews.
The interface is functional and often intuitive, but some reviewers still found it less elegant than Apple Watch-style software.
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 was judged through the lens of needs: reviewers often felt the S70 earns its price for serious golfers, but agreed it is overkill for basic yardage users.
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 were praised for looking better on the AMOLED screen and offering better everyday appeal than older golf watches.
Water resistance is consistently listed at WR50 or 50 meters, enough for common sports-watch use but not pitched as a dive tool.
Reviewers cited shower and swim use plus a 5 ATM rating as evidence that the S70 handles water exposure confidently.
Wellness coverage goes beyond raw sleep logs, with repeated mentions of HRV, skin temperature, recovery metrics, and alertness/readiness-style insight.
Wellness insights were a major positive, especially when the watch explained what sleep, workout, and energy metrics actually meant.
