Compare Tag Heuer Connected Calibre E4 vs Amazfit Active 3 Premium

Workout auto-detection is mixed: some sources say it auto-recognizes strength movements and several sports, while one hands-on review says it lacks automatic workout detection.

Reviewers liked that the watch uses Wear OS, Google Play, and installable apps, though the appeal is strongest when paired with TAG Heuer’s own software layer.

The app ecosystem is useful but bounded: reviewers mention hundreds of apps and Zepp App Store extras, while one notes apps must come from Zepp rather than Apple or Google stores.

Bands and clasps were consistently praised for comfort, softness, secure adjustment, and easy swapping, with several reviewers calling out premium rubber straps.

Band impressions are generally practical, with standard 20 mm quick-release or non-proprietary bands and an included silicone strap.

Battery life is generally acceptable for daily smartwatch use and better on 45mm models, but reviewers still describe charging as a regular daily or near-daily habit.

Physical controls are a strong point, especially the rotating crown and pushers, which reviewers found satisfying, customizable, and easier than touch alone.

Button controls are a clear strength, with four physical buttons praised for workouts, gloves, sweaty hands, and navigation without touch input.

Call handling is poor because multiple reviewers state the watch cannot take calls, even though it can receive call notifications.

Call handling is mostly supported through Bluetooth calling and a mic/speaker, though one preview transcript reports a no-speaker limitation.

Calorie usefulness is limited because weak heart-rate accuracy undermines calorie estimates, although the Wellness app does track calorie burn.

Calorie tracking is mentioned as part of the app ecosystem, but reviewer evidence does not deeply evaluate its accuracy or usefulness.

Charging convenience is strong thanks to a sturdy stand-style dock that doubles as a bedside display rather than a small puck.

Charging convenience is helped by long battery life and a familiar Amazfit magnetic charger used across several models.

Charging speed is decent, usually described around 70 to 90 minutes for a full charge, though one review notes there is no quick-charge mode.

Coaching features are a pleasant surprise, with animated guided workouts repeatedly praised as attractive, clear, and useful for casual exercise.

Coaching features are a major strength, including Zepp Coach, adaptive plans, training libraries, guided metrics, and beginner-friendly structure.

Comfort is generally strong, especially with the 42mm size, titanium versions, and adjustable clasp, though some heavier models are less ideal for overnight wear.

Comfort is consistently positive, with reviewers calling out the light feel, smaller size, and approachable wearability.

The companion app is viewed positively when used for watch faces, fitness data, and Wear OS 3 setup, with reviewers calling it slick and informative.

The Zepp companion app is mostly praised as clear, detailed, easy to set up, and useful, though one German review criticizes weak translations.

Contactless payments are well supported through Google Pay, and reviewers describe payment use as simple and available for shops or transit.

Heart-rate accuracy is inconsistent and often weak, with several reviews reporting large differences versus chest straps, Garmin, Oura, or Apple Watch.

Heart-rate accuracy is mixed: some tests report good chest-strap agreement, while others saw cadence-like behavior or imperfect interval tracking.

LTE connectivity is not supported, and reviewers repeatedly list cellular connectivity as a missing feature.

LTE connectivity is not available, so connected features depend on a nearby phone over Bluetooth.

Materials quality is excellent, with repeated praise for stainless steel, titanium, ceramic bezels, sapphire crystal, and luxury finishing.

Materials quality is a strength, with stainless steel, sapphire glass, and metal accents repeatedly mentioned.

Menu navigation is aided by the rotating crown and physical controls, though general Wear OS navigation quality depends on the software version.

Menu navigation is mostly smooth and button-aided, though some workout and map workflows confused reviewers or required leaving an activity.

Music controls are solid, with reviewers noting working playback controls and phone-free pause, play, and skip access.

Music controls and audio functions are present through phone control, playback widgets, podcasts, and music/podcast storage.

Onboard music support is good for Wear OS, with offline playlist syncing and downloads mentioned for supported music services.

Onboard storage is useful for maps, music, podcasts, and routes, but space is limited compared with higher-end Amazfit models.

The OS experience is mixed: Wear OS 2 drew frustration, while Wear OS 3 and TAG Heuer’s visual layer were described as smoother and more premium.

The Zepp OS experience is familiar and smooth, with reviewers describing it as similar to other Amazfit watches.

Outdoor visibility is a clear strength, with multiple reviewers saying the display is readable in bright sunlight.

Outdoor visibility is a major strength, supported by the bright 3,000-nit AMOLED display and direct-sun readability.

Pairing reliability is positive in the few direct tests, including automatic iPhone reconnection and quick, issue-free setup.

Pairing is generally easy, but one iPhone user noticed occasional brief syncing delays.

Recovery insight is limited; one review saw an estimated rest time, while another noted no deeper feedback on how to improve.

Recovery insights are a major part of the product, including recovery time, fatigue, exertion, HRV, sleep quality, and BioCharge/readiness-style data.

Reliability is mixed: general software stability is praised in one review, but notification delivery was only moderate in another.

Overall reliability is positive in hands-on use, though early heart-rate and map-transfer quirks keep it from being flawless.

Safety features are limited, with at least one reviewer specifically noting missing fall detection and a restrained feature set.

Safety and navigation features are strong for the price, including offline maps, turn-by-turn guidance, rerouting, POIs, and backtrack-style return options.

Size options are a strong advantage, with 42mm and 45mm versions broadening appeal across smaller and larger wrists.

Size options are limited because the watch comes in one case size, although reviewers also liked the smaller, more manageable form factor.

Sleep tracking is weak because reviewers say native sleep tracking is missing or not emphasized.

Sleep tracking is one of the best-reviewed attributes, with detailed stages, wakeups, HRV, breathing data, and sleep scores.

Step counting is passable but not exact, with reviewers finding roughly 1,000-step differences versus comparison devices.

Stress tracking is repeatedly included among the automatic health features and wellness insights.

Style and design are the product’s biggest strength, with reviewers consistently praising its luxury look, traditional-watch feel, and desirability.

Style and design are mostly positive for a premium-looking budget watch, but some reviewers wanted more color and strap choices.

Third-party app support is good through Google Play and Wear OS, with reviewers noting downloadable apps and installable fitness apps.

Third-party support is mixed: key training platforms like Strava, TrainingPeaks, Runna, and Intervals appear, but broader app-store access and some training-app links are limited.

Touchscreen responsiveness evidence is limited but positive, with reviewers reporting responsive interaction and very little latency.

Touchscreen use is functional, but reviewers emphasized the value of physical buttons and did not deeply praise touch responsiveness itself.

The interface is attractive and easy to use in TAG Heuer’s own apps, though broader Wear OS flow is less universally praised.

The interface is generally beginner-friendly, smooth, and jargon-free.

Value for money is the clearest tradeoff: reviewers admire the luxury execution but repeatedly say cheaper watches do more for far less.

Value for money is the strongest consensus point, with reviewers repeatedly contrasting the price with the premium build, maps, battery, and health features.

Voice assistant support is present and generally useful through Google Assistant, though evidence is limited and not a major focus.

Voice assistant support is present through Zepp Flow/AI assistant controls and commands, with generally positive but not deeply tested impressions.

Watch faces are a standout feature, repeatedly praised for detail, customization, TAG Heuer identity, and premium always-on presentation.

Watch face quality is mixed: there are Zepp App Store watch faces, but one reviewer questioned whether some looked AI-generated.

Water resistance is consistently listed at 50 meters or 5ATM, enough for swimming and daily water exposure but not intensive diving use.

Water resistance is solid for everyday use and swimming, with multiple reviews mentioning 5 ATM protection.
