Compare Amazfit T-Rex Ultra 2 vs Apple Watch SE 3

Reviewers found automatic workout or walk detection useful and generally dependable, though one noted occasional slower workout-end recognition.

The app ecosystem trails Apple and Garmin, with one review explicitly saying Amazfit is still a few steps behind those brands.

The app ecosystem is a major strength, with reviewers praising the Apple Watch App Store and broad app availability compared with rival budget watches.

Band quality is mixed, with one reviewer finding the silicone strap rigid while others liked the secure wider or included band.

Band support is a strength because the SE 3 uses Apple’s familiar strap system and has many Apple and third-party options.

Battery life is the strongest consensus positive, with reviewers reporting slow drain, multi-week use and long GPS endurance.

Battery life is the clearest mixed area: some reviewers saw all-day or better results, while others still treated it as a daily-charge watch.

Blood oxygen tracking is consistently present in the health stack, with reviews citing SpO2 or blood oxygen monitoring alongside heart-rate and stress features.

Blood oxygen tracking is consistently described as missing from the SE 3, making it a clear limitation versus Series and Ultra models.

Bluetooth connectivity is explicitly supported, including BLE and pairing with headphones or sensors.

Bluetooth support is present and useful for headphones and audio, though reviewers mostly mention it as part of the connectivity package rather than a standout feature.

Brightness is repeatedly praised, especially the 3,000-nit AMOLED display and its visibility in sunlight or glare.

Brightness is adequate for many reviewers, but the 1,000-nit display is repeatedly framed as weaker than the Series 11 in direct sunlight.

Build quality is widely praised, with reviewers describing sturdy hardware, rugged construction and a premium outdoor-watch feel.

Build quality is generally praised as light, well made, and attractive, with tougher glass helping the SE 3 feel less like a budget device.

Button controls are a strength, with reviewers appreciating large physical buttons, tactile feedback and the ability to use buttons outdoors.

Button and gesture controls are strongly received, especially the Digital Crown, side button, Double Tap, and Wrist Flick gestures.

Call handling is a practical positive, with multiple reviewers citing Bluetooth calls, a built-in speaker and mic, and wrist-call functionality.

Call handling is solid for a wrist device, with useful speaker, microphone, cellular, and voice isolation notes, though it is not ideal as a primary phone substitute.

Calorie tracking received limited but positive evidence through the Zepp food-logging feature, which helped one reviewer see trends and a typical daily count.

Calorie tracking is treated as part of the reliable core fitness feature set, with one reviewer noting workout calorie metrics matched comparison data.

Charging convenience is helped by long battery life and the ability to avoid frequent charging, though the lack of solar charging was noted.

Charging convenience improves with USB-C magnetic charging and fast top-ups, but sleep tracking still requires a daily charging routine for many users.

Charging speed is a repeated upgrade, with reviewers citing useful fast-charge top-ups and roughly 80 percent in around 45 minutes to an hour.

Coaching and workout-guidance features were mixed: Zepp Coach and voice memo tools were praised, while the climb-analysis feature was criticized for missing climbs.

Coaching features are useful but not deeply advanced; Workout Buddy is described as beginner-friendly, motivational, or basic depending on the reviewer.

Comfort is one of the main compromises: some found it wearable, but several reviewers called it bulky or uncomfortable for sleep.

Comfort is a strength, with reviewers calling the watch lightweight, unobtrusive, and well suited to sleep or smaller wrists.

The companion app is useful but imperfect: reviewers liked some media/app interfaces while criticizing route editing in Zepp.

Companion app quality is functional but split across Watch, Health, and Fitness apps, which can be useful yet occasionally tedious.

Contactless payments are uneven: NFC support exists in some contexts, but reviewers noted regional limits and reliance on Curve outside China.

Contactless payments are a strong Apple Watch staple, with Apple Pay repeatedly included among the SE 3’s core smartwatch strengths.

Cross-platform compatibility is weak because reviewers frame the SE 3 as an iPhone smartwatch and note it only works with iPhone.

Customization options are limited, especially because the watch was described as available in one size and color with strap swaps as the main personalization route.

Customization is strong across watch faces, metrics, widgets, bands, and gesture-driven controls.

Display quality is a major strength, with reviewers praising the large, bright AMOLED screen and clear viewing for maps and data.

Display quality is much improved by the always-on OLED screen, though thicker bezels and lower brightness keep it below Series and Ultra displays.

Durability is a major positive, with military-standard claims, sapphire protection, temperature resistance and rugged real-world impressions.

Durability is improved through tougher Ion-X glass and water resistance, but some reviewers still point to weaker scratch or dust protection than pricier models.

ECG functionality is absent, and reviewers repeatedly call this one of the main health-feature tradeoffs.

Fit is best for larger wrists, with repeated warnings that smaller wrists may struggle with the size and heft.

Fit is favorable for smaller wrists and sleep tracking, though one reviewer found the older chassis less flush than newer models.

Fitness tracking accuracy was broadly usable for normal tracked modes, but one data-heavy review warned that wrist heart-rate issues can affect vigorous exercise results.

Fitness tracking accuracy is a strong point, with reviewers reporting accurate workouts and close agreement with comparison devices.

GPS accuracy was one of the strongest areas, with many reviewers reporting accurate, fast, strong or spot-on tracks, though some routing behavior was still uneven.

GPS accuracy is generally strong for a single-band Apple Watch, with caveats in tall-building or canyon-like conditions.

Reviewers found general health data respectable overall, with one review saying night health stats looked close to other wearables, though another framed the broader sensor stack as adequate rather than class-leading.

Health tracking accuracy is solid for the essentials, especially heart rate, sleep, and workouts, while advanced sensors are omitted.

Heart-rate accuracy was mixed: some reviewers found it on point or solid, while others saw cadence lock, rough outdoor-run results, and weaker performance during vigorous exercise.

Heart-rate accuracy is repeatedly praised, with reviewers finding close agreement against straps or other watches.

LTE and cellular connectivity are improved by 5G, with reviewers noting better coverage, calls, texts, messages, and downloads away from the phone.

Mapping and navigation are useful thanks to Apple Maps, offline maps, Find My basics, and Compass Backtrack, though precision finding is limited.

Materials quality is strong, centered on Grade 5 titanium, sapphire glass and a rugged polymer/titanium construction.

Materials quality is good for the price, with aluminum and Ion-X glass, but premium titanium, sapphire, and some rugged ratings remain reserved for higher models.

Menu and navigation flow drew both praise and criticism, from easy on-watch navigation to laggy cycling directions and odd turn prompts.

Menu navigation is easy and fast, helped by watchOS, the Digital Crown, touch controls, and one-handed gestures.

Music controls are useful for phone playback, but streaming-service limitations reduce the broader music experience.

Music controls are a strength, including Apple Music pairing, media controls, and playback improvements.

Onboard storage is generous for maps and local media, including podcasts and audio files, but subscription streaming support remains limited.

Onboard storage and offline playback are improved, with 64GB storage and support for music or media without the phone nearby.

The operating-system experience is functional and phone-connected, though the evidence is not as deep as for hardware, GPS and battery life.

The operating system experience is a major strength; reviewers praise watchOS 26 as polished, cohesive, and rich in Apple Watch features.

Outdoor visibility is excellent across reviews, with repeated evidence that the screen is readable in direct sun, snow glare and outdoor mapping use.

Outdoor visibility is usable but not class-leading, with the 1,000-nit screen and direct sunlight repeatedly cited as limits.

Pairing and app reliability looked strong in the direct evidence, with one review saying it did not disconnect or struggle with transfer.

Pairing and iPhone integration are strong, with reviewers praising how well the watch syncs, routes notifications, and pairs with Apple services.

Recovery features are meaningful but not uniformly mature, with reviewers citing BioCharge, training load and recovery insights while noting some uncertainty in usefulness.

Recovery insights are present through training load, Vitals, sleep score, and workout feedback, but they are not as deep or prescriptive as some rivals.

Reliability is mixed because the hardware is solid but multiple reviewers flagged headline software features that did not work reliably.

Reliability appears strong in everyday use, with reviewers emphasizing smooth performance and lack of issues in ordinary tasks.

Safety features are strong for outdoor use, including the flashlight, SOS signaling and diving-related functionality.

Safety features are a major strength, including fall detection, crash detection, emergency SOS, heart-rate alerts, and Compass Backtrack.

Size options are inconsistent in the review evidence, with one review saying one size and color while another says two sizes are available.

Size options are adequate and familiar at 40mm and 44mm, with the smaller size appealing to smaller wrists, though color choices are limited.

Sleep tracking was treated as useful but imperfect, with reviewers noting sleep-stage support while also calling scores funky and REM/RAM-stage detection weak.

Sleep tracking is useful and generally accurate for time and stages, but sleep score is sometimes described as simple or limited.

Notification support is mentioned as part of normal smartwatch use, but review evidence is limited and does not deeply test notification handling.

Notifications are a core strength, especially with always-on viewing, wrist vibration routing, and gestures for dismissal or management.

Smartwatch features cover basics like calls, calendar-style features and assistant support, but reviewers consistently framed them as less premium than Apple or Garmin.

Smartwatch features are excellent for the price, with reviewers emphasizing that it feels like a full Apple Watch rather than a stripped-down tracker.

Software smoothness is mixed: reviewers saw minor lags and meaningful navigation improvements, but also major launch issues with headline functions.

Software smoothness is one of the clearest strengths because the S10 chip keeps watchOS, apps, and gestures fast and responsive.

Step counting appears as part of the core activity toolkit, though reviewers discuss the feature more than rigorous step-count accuracy.

Stress tracking is well represented as part of the health suite, and one review tied improved heart-rate accuracy to better stress and training-load assessments.

Style and design are polarizing: one review called it too masculine, while another found the design more refined and premium.

Style and design are mixed: reviewers like the familiar Apple Watch look but often criticize the older body, thicker bezels, and limited colors.

Third-party app support is a weakness, with reviewers noting limited third-party apps and lack of Spotify support.

Third-party app support is strong because the SE 3 retains Apple’s large app store and broad developer support.

Touchscreen responsiveness is generally good, though one reviewer found it almost too sensitive at times.

Touchscreen responsiveness is strong, with reviewers saying touch, buttons, gestures, and everyday controls work promptly and fluidly.

The user interface is familiar within Amazfit's lineup and functional, with one reviewer calling it nearly identical to related models.

The user interface is easy, clean, and cohesive, especially with watchOS 26 and the familiar watch face/home structure.

Value for money is sharply split: many reviewers praised the Garmin-like value, while others thought the $549 price was too high given software gaps.

Value for money is the strongest consensus attribute, with reviewers repeatedly saying the SE 3 offers near-Series functionality at a much lower price.

Voice assistant quality looked solid in the reviews that tested it, especially for Zepp Flow voice control and watch-setting interactions.

Voice assistant quality improves with on-device Siri and the S10 chip, making requests faster and more useful than earlier SE models.

Watch-face quality is supported by customizable faces and access to additional faces through the Zepp app store.

Watch face quality is praised through attractive, high-quality options and watchOS 26 face support.

Water resistance is consistently strong, with 10 ATM ratings and dive-oriented evidence across multiple reviews.

Water resistance is solid for typical use, with reviewers noting 50-meter or 164-foot resistance and swim tracking, but not advanced dive sensors.

Wellness insights include BioCharge, Jet Lag Manager and related fitness-readiness views, giving users an energy and recovery-oriented picture beyond raw activity stats.

Wellness insights are useful for mainstream users through sleep score, sleep apnea alerts, wrist temperature, Vitals, and heart-rate notifications.

Wi-Fi connectivity is explicitly listed by reviewers and appears as part of the watch's connectivity stack.

Wi-Fi is adequate but not premium, with reviewers noting 2.4GHz-only or Wi-Fi 4 support rather than dual-band.

Workout variety is a clear strength, with reviewers repeatedly citing more than 180 modes and coverage of niche outdoor and sport profiles.

Workout tracking variety is strong, covering many sports, workouts, running metrics, swimming, and common gym activities.
