Compare CMF Watch 3 Pro vs Google Pixel Watch 3

Activity auto-detection exists and can work for walks and common activities, but one reviewer warns that manual workout starts are still safer.

Auto-detection was usually praised for reliable workout or bedtime recognition, though one reviewer said it missed training sessions.

The app ecosystem is limited: syncing with fitness services helps, but the proprietary OS lacks the breadth of Wear OS or full third-party app access.

Reviewers liked Wear OS app availability and found the platform close enough to mature smartwatch ecosystems for most users.

Band quality is mixed: several reviewers like the soft, replaceable strap, while others call it floppy, lighter-quality, or irritating.

The default band could be comfortable, but reviewers disliked the proprietary connector, strap mechanism, and 45mm band reset.

Battery life is one of the strongest points, with many reviewers seeing multi-day to week-plus endurance and some highlighting 13-day claims or better-than-expected results.

Battery life was a consistent improvement, especially on 45mm models, generally landing between a full day and close to two days.

Blood oxygen tracking is present, with alerts or spot readings mentioned, and one reviewer found readings close to a pulse oximeter, though reviewers did not deeply validate it.

Blood oxygen data appears as part of the health metrics stack, but reviewers discussed it as one metric rather than a headline strength.

Bluetooth connectivity is mostly stable once paired in positive reviews, though one reviewer notes the connectivity stack is limited to Bluetooth Low Energy.

Bluetooth was viewed positively for upgraded specs and stable phone pairing, with some ecosystem unlocking benefits tied to connectivity.

Brightness is adequate in some normal situations, but reviewers often call it low by current standards or wish it were brighter.

Brightness drew strong praise after the jump to 2,000 nits and better sunlight readability.

Build quality divides reviewers: several find the fit and finish surprisingly good for the price, while others call it cheap, plasticky, rattly, or toy-like.

Build quality felt refined and premium, though ruggedness concerns remain separate from the basic construction impression.

Button controls are mostly liked, especially the crown, haptics, and shortcuts, but reviewers also note size or underused crown interactions.

The crown and side buttons were generally responsive, with reviewers appreciating the haptic crown and physical controls.

Call handling is better than expected for a budget smartwatch, with reviewers reporting usable microphones and clear calls, though speaker loudness can limit outdoor use.

Call features were useful, especially Ask to Hold and watch-based call handling, with Pixel phone integration adding value.

Calorie data is useful as part of workout summaries for casual tracking, but reviewers treat it as general guidance rather than laboratory-grade measurement.

Calorie tracking was treated as useful for general fitness context, not as a dedicated precision tool.

Charging convenience is a consistent complaint because the proprietary magnetic connector is flimsy, easy to dislodge, or awkward to use.

Charging convenience was mixed: the puck could be secure and useful for quick top-ups, but some found accessory options or cable behavior limiting.

Charging speed is acceptable rather than exceptional, usually described around 90 to 99 minutes for a full charge or decent partial top-ups.

Charging speed improved meaningfully, with multiple reviewers noting fast partial top-ups and shorter full-charge times.

Coaching features are a clear selling point, especially the running coach and AI plan guidance, although reviewers treat it as helpful rather than flawless.

Coaching improved substantially through custom runs, voice cues, Cardio Load, and AI-style suggestions, though it still leans runner-first.

Comfort is generally helped by the low weight, though size, poor fit for some wrists, and one uncomfortable experience keep it from being universally comfortable.

Comfort was a recurring strength, with reviewers finding both the strap and larger model wearable day and night.

The companion app is cleaner and more polished than before, but limitations around workout records, battery drain, language issues, exports, and data depth remain.

The Fitbit app and data presentation were repeatedly praised for clarity and explanation, though Premium still complicates the value.

Contactless payments are a clear miss: multiple reviewers note the absence of NFC or wallet payments.

Contactless payments are well supported through Google Wallet or Google Pay and treated as a normal smartwatch strength.

Cross-platform compatibility is a strength for a budget watch, with reviewers noting Android and iPhone support and basic assistant use across platforms.

Compatibility is good across Android phones but limited by no iPhone support and a few Pixel-exclusive features.

Customization is mixed: watch faces, widgets, gestures, AOD and bands give flexibility, but the lost interchangeable bezel and limited widget or face storage disappoint reviewers.

Customization is decent for watch faces, tiles, and runs, but sport data screens and non-running workouts remain constrained.

Display quality is generally praised for the AMOLED panel, larger size, sharpness, and readability indoors, even when brightness has limits.

Display quality was one of the strongest upgrades thanks to bigger screens, slimmer bezels, sharper visuals, and more usable space.

Durability evidence is limited but mixed: one reviewer noticed an early screen scratch, while another found the body and screen held up after daily use and a drop.

Durability was a repeated caveat because Gorilla Glass and the domed design lack the rugged protections of some rivals.

ECG is present as part of the health suite, but reviewers tended to mention it alongside other sensors rather than testing it deeply.

Fit is a weakness for smaller wrists in the available evidence, with reviewers noting poor fit or the watch being too large.

Fit was praised through the flush case, comfortable underside, and wearable larger size.

Fitness tracking accuracy is acceptable for casual use in some reviews but unreliable in others, especially for sleep-related confidence, workouts, running, and weightlifting.

Fitness tracking accuracy was generally strong for workouts and heart-rate-based exercise logging, especially for casual and mainstream use.

GPS is generally praised after the upgrade to dual-band tracking, with fast lock times and strong route accuracy, though one scientific reviewer questioned recording frequency.

GPS opinions were mixed to negative: lock-on and casual tracking could be fine, but precision lagged behind stronger sports watches.

Reviewers describe the health suite as broad for the price, with heart rate, sleep, stress and blood oxygen options, but accuracy and depth are inconsistent across tests.

Health tracking accuracy was praised when compared with Apple Watch, Fitbit expectations, and reviewer lived experience.

Heart rate accuracy is one of the most divided areas: some reviewers saw close agreement with reference devices, while others found misses during runs, workouts, or loose wear.

Heart rate accuracy was a standout, with several reviewers finding it close to chest straps or leading wearables.

LTE is available but typically framed as an optional paid upgrade rather than a transformative feature.

Offline Google Maps improved navigation utility, but workout-integrated navigation still lagged specialized sports watches.

Materials are mixed, with metal or aluminum elements helping the watch feel better than expected, but plastic backs, bezels, and sensor areas reduce the premium feel.

Materials felt premium with aluminum cases and curved Gorilla Glass, though the absence of sapphire limited rugged confidence.

Menu navigation is straightforward and crown-assisted, though some reviewers note the interface does not fully exploit the crown or gestures.

Menu navigation improved with the grid launcher and intuitive controls, but some Wear OS screens still required extra scrolling.

Music controls are useful for phone playback, including album artwork in one review, but the watch is not presented as a standalone music device.

Music controls and media access were useful, including workout-screen controls and phone or streaming-player control.

Onboard music storage is absent, limiting the watch for phone-free exercise with wireless earbuds.

Onboard storage helps with offline maps and music, making phone-free runs more practical.

The operating system experience is repeatedly described as polished, smooth, and quality-feeling for the price.

Wear OS was usually described as smooth, polished, and increasingly mature, especially in Google’s own ecosystem.

Outdoor visibility is a recurring weakness, especially with the always-on display, direct sunlight, or polarized sunglasses.

Outdoor visibility was very strong thanks to the 2,000-nit display and better sunlight readability.

Pairing reliability is mixed: some reviewers found setup or phone switching easy, while others had a difficult pairing process or disconnections from the app.

Pairing and setup were reliable in the scored reviews, including easy setup and stable use across Android phones.

Recovery insights show up as estimated recovery time, VO2 max, training load, and recovery metrics, giving runners and casual athletes more guidance than expected at this price.

Recovery guidance improved through Readiness, Target Load, and Cardio Load, giving more actionable daily training context.

Reliability is mixed, with reviewers citing notification sync issues, app optimization problems, app disconnects, and work-in-progress software behavior.

Reliability was strongest around battery consistency and stable software, though GPS and durability kept it from being flawless.

Safety features were robust, including fall detection, emergency calls, check-in tools, and loss-of-pulse detection.

Size options are limited to one case size, which reviewers repeatedly flag as a problem for smaller wrists.

The new 45mm option was one of the most agreed-upon wins, broadening appeal and improving screen and battery life.

Sleep tracking ranges from impressive duration or comparative results to very poor awake detection, so reviewers do not agree that it is dependable for serious sleep analysis.

Sleep tracking was generally viewed as accurate or useful for timing and sleep context, though not always deeply insightful.

Notifications are useful for quick wrist checks and preset replies, but syncing and clearing behavior can be one-way or limited depending on phone platform.

Notifications were a core strength, with prompt delivery and enough wrist interaction to reduce phone use.

Smartwatch features cover basics such as notifications, camera shutter, calls, recorder, weather, music control, calendar, assistant access, and news, but not advanced platform features.

Smartwatch features were broad, including Google app integrations, smart home control, Recorder, TV remote, Wallet, and safety tools.

Software smoothness is generally strong, with several reviewers praising fluid animations and scrolling, but one negative review saw lag and another saw small pauses.

Software smoothness was highly rated, with reviewers noting snappy app loading, no perceptible lag, or no stutters.

Step-counting evidence is limited and mixed, with one reviewer seeing a sizeable difference between the watch and Google Fit by the end of the day.

Step counting tested very accurately in one review and reasonably close in another.

Stress tracking and guided breathing are repeatedly mentioned, but at least one long-term reviewer found stress readings temperamental and not reflective of real stress.

Stress tracking was useful for some, especially cEDA responsiveness, but other reviewers found the explanations less actionable.

Style and design are among the most praised areas, although a few reviewers dislike the plasticky or average feel.

Style and design were a major strength, with repeated praise for the pebble-like, elegant, distinctive look.

Third-party app support is weak because reviewers repeatedly note that apps cannot be installed or accessed like on fuller smartwatch platforms.

Third-party support was good for apps, but external sensor pairing and some data export workflows were limiting.

Touchscreen responsiveness is mixed: some reviewers praise smoothness while others report lag, missed swipes, or always-on behavior that does not work as expected.

Touch input was responsive in normal use, though sweat or water could make it less dependable.

The user interface earns praise for being clean, polished, readable, and visually appealing, especially with Nothing's minimal monochrome style.

The interface was clean and straightforward overall, despite some round-screen inefficiencies and sparse layouts.

Value for money is strong overall because many reviewers find the design, display, battery, GPS, and basics impressive for around $99, despite harsher dissent.

Value was mixed: reviewers liked the watch but cited high pricing, cheaper alternatives, or weak upgrade need.

Voice assistant support is useful when it triggers Siri, Gemini, or ChatGPT through a compatible phone, but ChatGPT support is limited and inconsistent across phones.

Google Assistant worked well for some tasks, but the lack of Gemini and awkward voice experiences limited enthusiasm.

Watch faces are a standout design strength, with many reviewers praising the quantity, style, AOD support, and creative video or AI face options.

Watch faces were mixed, with some reviewers liking Active but others wanting more variety and better defaults.

Water resistance is a major caveat: ratings are mentioned repeatedly, but reviewers stress that swimming, pools, oceans, or showers are not recommended.

Water resistance was consistently supported through IP68 and 5ATM claims, suitable for showers and swimming contexts.

Wellness insights are shallow compared with the raw metrics: reviewers wanted more written explanations or practical advice from sleep and health data.

Wellness insights improved through Morning Brief, Readiness, Cardio Load, and Fitbit health summaries.

Wi-Fi is not available according to the reviewer evidence, which limits independent connectivity.

Wi-Fi connectivity improved through faster 5GHz support and was referenced as part of stable daily connectivity.

Workout variety is a major strength: reviewers consistently note the huge list of sports modes, often around 131 options, covering mainstream and niche activities.

Workout variety is broad enough for casual users, but reviewers repeatedly noted the strongest new tools favor runners.
