One review explicitly notes that blood oxygen tracking is not offered on the M2 and is reserved for a higher-end Polar model.

The watch is widely framed as rugged and suited to adventurous use.
Multiple reviews note onboard ECG support for rhythm checks through Garmin’s sensor and app setup.
Fit is secure once tightened properly, and included strap sizing helps it accommodate different wrists.

GPS performance is mixed but usually competent: several reviews report good everyday tracks, while others document clear misses in tougher scenarios.
GPS performance is a clear strength, with spot-on tracks, no notable errors, and strong race accuracy.
Health tracking is generally viewed as accurate and useful, especially around sleep and overnight recovery patterns.
Heart rate accuracy is one of the M2's stronger areas for many workouts, but multiple reviews still recommend a chest strap when precision really matters.
Reviewers consistently describe heart rate readings as close to chest straps, with only minor lag noted during sudden changes.
LTE is the headline upgrade and usually works well for calls, texts, LiveTrack, and phone-free use, but not every reviewer found it fully dependable.
Materials are practical rather than premium, combining plastic or polymer construction with nicer accents like stainless steel or mineral-style elements.
Titanium and sapphire construction is repeatedly cited as hardy and premium.
Menu navigation is learnable and workable, but some actions take too many presses and certain menus feel sluggish.
One review praises quick access to key information without extra swiping, suggesting efficient menu flow.
Music controls are useful for basic phone playback control, but they remain simple and depend on the phone being nearby.
The watch does not store music locally; it only controls audio playing on a connected phone.
Reviews confirm onboard music storage and offline downloads, including linked streaming-service support.
The operating experience is straightforward and athlete-focused rather than flashy, prioritizing practical training use over richer smartwatch polish.

Safety and navigation help are minimal, centered mostly on Back to Start rather than fuller route guidance.
LiveTrack, SOS, and emergency contact tools add meaningful safety value, though subscription requirements and some limits temper enthusiasm.

Size choice is a weak point because there is no 43mm Pro and the available models run large.
Sleep tracking is one of the most consistently praised features, with reviewers often calling it accurate and reliable.
Phone notifications work, but filtering, timing, and workout behavior are limited enough to frustrate some users.
Smartwatch features are present but basic, covering notifications, weather, simple watch-face options, and music controls without matching richer smartwatch rivals.
One review calls it Garmin’s smartest watch yet, largely because cellular adds more phone-free functions.
Software smoothness is mixed: some reviewers call the interface smooth and responsive, while others notice lag and slower page transitions.
Software polish looks uneven: one reviewer calls daily use smooth, while another reports bugs and restarts.
Available evidence suggests step counts are reasonably close to other trackers, though this attribute is less heavily tested than GPS or heart rate.
Design is widely praised as sporty, more stylish than earlier versions, and attractive enough for all-day wear.
Despite the rugged build, reviews also describe the design as stylish and premium-looking.
Third-party app support is a plus, with reviews specifically mentioning services like Strava and broader export options.
