Compare OnePlus Watch 3 vs Garmin Epix Pro (Gen 2)

Auto workout detection is explicitly supported for common activities, though reviewers focused more on workout depth than detection behavior.

Reviewers only touched on limited auto-detection behavior: Garmin Connect can automatically assign gear to activities, and strength mode detected exercises like squats, so support is useful but narrow.

Reviewers consistently credit Wear OS and Google services with giving the watch a strong Android app ecosystem.

The Garmin ecosystem is described as expandable through a software marketplace and Connect IQ access, though the experience can feel more tool-like than slick.

Band feedback is mixed: quick-release and strap compatibility are positives, but smaller 43mm strap sizing and basic rubber bands drew criticism.

Bands are generally praised for quality and QuickFit swapping, with long-term evidence that the band holds up, though one white strap got dirty in use.

Battery life is the clearest strength, with reviewers repeatedly reporting multi-day endurance that beats most Wear OS rivals.

The functional rotating crown is one of the most praised upgrades, improving scrolling, zooming, shortcuts, and tactile control.

Button controls are a major practical advantage for workouts, with multiple reviewers praising tactile operation, though one long-term user found the many buttons confusing.

Call handling works and voice quality is generally acceptable, though one reviewer found the speakerphone too quiet.

Call handling is limited in the available evidence, especially on iPhone, where one reviewer said users cannot respond to texts or calls.

Calorie tracking is mixed: one review lists calorie data as useful, while another found the calorie goal too easy to trigger.

Calorie tracking is useful mainly through Garmin Connect and MyFitnessPal integration, with total, base, and active calories visible.

Charging convenience is strong thanks to a compact magnetic dock, USB-C-friendly cradle design, and easy top-ups.

Charging convenience is a weakness in the review evidence because Garmin still relies on its proprietary plug-in charger and lacks solar charging on Epix Pro.

Charging speed is repeatedly praised, with many reviews reporting quick top-ups and full charges in roughly an hour or less.

Charging speed is a clear upgrade, with reviewers citing full charging in about an hour, under-an-hour charging, and meaningful battery gains from short top-ups.

Garmin Connect is repeatedly valued for depth, training plans, and data, though watch customization from the companion app remains limited.

Contactless payments are well supported through Google Wallet or Google Pay and reviewers did not report major payment issues.

Garmin Pay is useful when supported, with reviewers praising tap-to-pay convenience, but UK bank support was criticized as limited.

Compatibility is limited to Android; reviewers repeatedly note that iPhone users cannot use the watch.

The watch works with both Android and Apple phones, but reviewers consistently note Android integration is better because iPhone replies and call responses are restricted.

Customization is good for buttons, faces, tiles, and controls, though the companion app and some watch faces could be more flexible.

Customization is broad across bands, apps, watch faces, data pages, and workouts, though some reviewers note it can take work to set up.

Display quality is consistently strong, with reviewers praising the AMOLED panel, sharpness, responsiveness, and overall look.

The AMOLED display is a highlight across reviews: vivid, crisp, readable, colorful, and a major reason to choose Epix over MIP-display alternatives.

Durability is a strength on the larger model, with sapphire, water ratings, and MIL-STD references, though the 43mm model makes some cuts.

Durability is a strong theme, with sapphire glass, rugged construction, and long-term reports of no front-face scratches after heavy use.

ECG support is a major caveat: hardware or global support exists, but US and North American availability is repeatedly criticized.

ECG evidence is mixed by review timing: one source notes a firmware update enabled ECG, while another earlier review says it was not yet available.

Fit is the most divisive physical issue, with larger models often feeling oversized while the smaller version helps but makes tradeoffs.

Fit depends heavily on size and wrist shape; smaller case options help, but a 47mm unit still felt ungainly on a very small wrist.

Fitness tracking accuracy is generally good for casual and running use, though reviewers did not treat it as a Garmin-level sports watch.

Reliability is generally good in long-term software use, but comfort problems and occasional responsiveness delays keep it from being flawless.

Reliability is strong in the available evidence, with one reviewer calling Garmin devices extremely reliable and another preferring Epix Pro stability over a newer model.

Safety features are mixed: fall detection and SOS appear in some reviews, while another reviewer wished for crash and fall detection.

Safety features are centered on the LED flashlight, strobe modes, visibility options, and LiveTrack-style use, and reviewers found the flashlight more useful than expected.

Size options are mixed: the smaller 43mm addition helps, but many reviews criticize the large model or limited choices.

Size options are a broad positive because Epix Pro comes in 42mm, 47mm, and 51mm, finally covering smaller and larger wrists.

Sleep tracking is broadly positive, with several reviewers finding detection and stage tracking useful, though some comparisons disagreed.

Sleep tracking accuracy is mixed but improving: some reviewers trust it or find sleep timing accurate, while others still compare it unfavorably with Oura or report occasional misses.

Stress tracking and wellness scores are mixed: some find them useful, while others call the insights vague or not very actionable.

Stress tracking feeds Garmin’s Body Battery and readiness-style insights, with one reviewer noting stress clearly depletes the Body Battery estimate.

Style is subjective: some reviewers love the traditional circular look, while others dislike the 43mm glossy design.

Style is rugged, serious, and tool-like rather than elegant, which some reviewers loved and others framed as a matter of taste.

Third-party app support is strong because Wear OS provides Play Store access and popular apps like Strava, Spotify, Audible, and AllTrails.

Third-party support appears through Connect IQ, letting users add watch faces, data fields, widgets, and apps.

Touch responsiveness is praised where cited, with the display described as sharp, vibrant, and responsive.

Touchscreen responsiveness is generally positive, especially for maps and daily use, with one reviewer praising it as responsive without being overly sensitive.

The user interface is the weakest software-area citation, with one reviewer calling it sluggish and unintuitive in places.
