Product 2: Garmin Forerunner 570
3.7

The app ecosystem is useful but not expansive. Reviewers mention ConnectIQ apps and data fields, while also noting that Garmin’s ecosystem feels more limited than watchOS or Wear OS.

band quality
Product 1: OnePlus Watch 3
3.3

Band quality is mixed: the 46mm model’s fluoro-rubber strap was viewed as solid and integrated well, while a 43mm reviewer called that model’s strap basic.

Product 2: Garmin Forerunner 570
4.5

Product 1: OnePlus Watch 3
3.7

The rotating crown and buttons are much improved overall, though one reviewer still disliked how useful the hardware buttons were during workouts.

call handling
Product 1: OnePlus Watch 3
3.5

Calls work directly from the watch and are generally serviceable, but multiple reviewers noted that speaker volume is limited.

Product 2: Garmin Forerunner 570

Product 2: Garmin Forerunner 570
No score yet
charging convenience
Product 1: OnePlus Watch 3
4.5

Charging convenience is strong thanks to a magnetically attached dock that seats easily and, in some reviews, a handy USB-C-based cradle design.

Product 2: Garmin Forerunner 570
4.6

Coaching features are well developed, especially for runners and triathletes. Garmin Coach plans, daily suggestions, and structured guidance were consistently praised.

contactless payments
Product 1: OnePlus Watch 3
4.4

Contactless payments work well through Wear OS, with reviewers reporting no major issues using wallet features.

Product 2: Garmin Forerunner 570
4.3

NFC payments are available, giving the watch a useful everyday smartwatch feature beyond training tools.

cross-platform compatibility
Product 1: OnePlus Watch 3
3.1

Compatibility is good across Android brands, but the watch is not iPhone-compatible, which sharply limits cross-platform use.

Product 2: Garmin Forerunner 570
4.4

Cross-platform support looks good overall, with smooth iPhone use noted in one review and phone-assistant access highlighted in another.

Product 2: Garmin Forerunner 570
4.8

Display quality is excellent. Reviewers repeatedly call the AMOLED screen brighter, sharper, clearer, and more vivid than the previous generation.

durability
Product 1: OnePlus Watch 3
3.7

Durability is strong on the main model thanks to high protection ratings, while the 43mm version drew complaints for cutting some durability hardware and certifications.

Product 2: Garmin Forerunner 570
4.6

Durability impressions are positive. Reviewers mention scratch resistance, pristine condition after use, and very little visible wear over time.

ECG functionality
Product 1: OnePlus Watch 3
3.3

ECG support is region-dependent: where enabled it works well, but North American reviewers repeatedly flagged that it is unavailable there.

Product 2: Garmin Forerunner 570
1.5

ECG is a clear miss. Reviewers repeatedly call out that the Forerunner 570 lacks ECG despite using Garmin’s newer sensor hardware.

fit
Product 1: OnePlus Watch 3
3.3

Fit depends heavily on wrist size and model choice; the 43mm improves wearability for smaller wrists, while the larger model can sit awkwardly.

Product 2: Garmin Forerunner 570
4.8

Fit is excellent when sized correctly, with reviewers describing the watch as secure, flush on the wrist, and almost second-skin-like.

fitness tracking accuracy
Product 1: OnePlus Watch 3
4.5

Product 2: Garmin Forerunner 570
4.6

Heart-rate tracking is a major strength. Multiple reviewers say it stays close to chest straps, performs well in intervals, and is one of Garmin’s better recent sensors.

LTE connectivity
Product 1: OnePlus Watch 3
1.5

Product 2: Garmin Forerunner 570
No score yet
materials quality
Product 1: OnePlus Watch 3
3.7

Materials are premium on the main model, with stainless steel, sapphire, and titanium frequently mentioned, but the 43mm trims some of those upscale materials.

Product 2: Garmin Forerunner 570

Product 1: OnePlus Watch 3
4.4

Onboard storage is useful enough for local media, with reviewers specifically mentioning space for playlists, music, and podcasts.

Product 2: Garmin Forerunner 570
4.0

Onboard music storage is useful but not generous. Reviews note 8GB of storage and MP3 support, with some calling the capacity a bit stingy.

operating system experience

4.4

The interface is widely praised for feeling slicker, cleaner, more intuitive, and more modern than older Garmin implementations.

value for money
Product 1: OnePlus Watch 3
4.0

Value for money is strong overall, especially on the 46mm model, though some reviewers felt same-price Pixel and Galaxy alternatives were harder to beat in feature depth.

Product 2: Garmin Forerunner 570
2.7
