Compare Apple Watch SE 3 vs Samsung Galaxy Watch 9

Heart-rate tracking drew strong praise across testing, with reviewers saying it aligned well with comparison devices and remained usable even in harder workouts.

Heart-rate results are mixed. Several controlled workouts track closely to chest straps, but other tests show startup errors, cadence lock, wider ranges, or weaker performance in difficult activities.

GPS accuracy was mostly praised for everyday workouts, though reviewers noted single-band GPS can wander in dense urban or more challenging environments.

Dual-frequency GPS is usually a strength, producing accurate routes in open areas, cities, and even dense woodland. Some tests still show slow initial lock, cut corners, building errors, or imperfect elevation.

Fitness tracking accuracy was a clear strength, with reviewers reporting reliable workout, activity, and comparison-test results for the price.

Fitness tracking is generally reliable across common workouts, with strong results for runs and everyday exercise. Accuracy can vary by activity, and tougher motion patterns expose more errors.

Sleep tracking was generally useful and often accurate enough, though several reviewers felt Apple’s Sleep Score was simpler than competing systems.

Sleep tracking is often very good, with some tests closely matching dedicated reference devices and accurately capturing sleep timing. Other reviewers report optimistic scores, missed wake-ups, or gaps, so consistency is not perfect.

Workout variety was viewed very positively, with reviewers noting broad sport profiles and nearly the same workout options as pricier Apple Watches.

Workout coverage is broad enough for most casual and serious users, spanning common gym, run, swim, and outdoor activities. Dedicated athletes may still miss specialized modes found on Ultra or sports-watch rivals.

Recovery-related evidence was limited, but one fitness-focused review valued training-load tracking as a way to monitor workout volume over time.

Cardio Load and related recovery guidance can help decide when to push harder or back off. Some runners find the targets jumpy or overly strict, so the guidance is not universally trusted yet.

Workout Buddy and coaching features were appreciated as helpful motivation, though reviewers often described them as basic, repetitive, or hit-or-miss.

Sleep and training coaching are generally useful for turning raw tracking into practical goals. They are most valuable when enough nights and workouts have accumulated for personalized guidance.

Calorie tracking appeared as part of the useful core fitness toolkit, with one test finding calorie and distance figures matched a comparison watch exactly.

Calorie estimates drew a clear accuracy complaint, with one long-term tester finding workout calories consistently overestimated enough to reduce their usefulness.

Blood oxygen tracking was consistently treated as a missing premium health feature, with reviewers noting it remains reserved for higher-end Apple Watches.

Blood-oxygen readings looked very close to a medical-grade pulse oximeter in one direct comparison, giving this metric a strong accuracy result.

Reviewers described the core health basics as adequate or mostly complete, especially heart-rate alerts and general tracking, while noting that advanced sensors remain absent.

Core health measurements compare well with reference devices in several tests. Body-composition and broader health readings are useful for trends, though they should not be treated as medical-grade conclusions.

Wellness insights were considered helpful for beginners or casual users, especially Sleep Score, sleep apnea alerts, and the Vitals-style health context.

Samsung packs in a remarkably broad, subscription-free health suite with Vitals, Heart Health, Fitness Index, sleep and more. The main tension is interpretation: some find the context useful, while others see too many disconnected scores.

Battery life was the main practical compromise, ranging from excellent in some tests to daily-charge frustration in others.

Battery life is the clearest recurring weakness. A few testers approach two days or beat expectations, but most report daily charging, heavy drain with workouts or AOD, and little improvement over recent Galaxy Watches.

Charging speed improved substantially over the SE 2 and was usually praised, even when still slower than pricier Apple Watches.

Charging speed is a major consensus complaint, often taking roughly 80-120 minutes and sometimes longer. A few tests were quicker, but inconsistency and slow short top-ups remain common frustrations.

Charging convenience was mixed because faster top-ups help, but sleep tracking still forces many users into a daily charging routine.

Charging is inconvenient for a watch built around round-the-clock health and sleep tracking. Daily top-ups and the loss of phone-based PowerShare make it harder to keep the watch on the wrist continuously.

Comfort was a consistent strength, especially for sleep, smaller wrists, and unobtrusive daily wear.

Comfort is one of the Watch 9's strongest traits. Its thin, light body sits close to the wrist, works well for sleep tracking, and is frequently described as easy to forget you're wearing.

Materials quality evidence was limited but positive, centered on the aluminum case, rounded body, and premium-looking construction.

The aluminum body keeps the Watch 9 light and comfortable, but reviewers comparing it with titanium Ultra models find it less rugged and less premium.

Band quality evidence was limited but very positive, with praise for easily replaceable Apple Watch bands.

Band impressions vary widely by material and wrist. Some praise the light, soft feel and easy changes, while others find the silicone sweaty, sizing awkward, or Samsung's first-party bands poor value.

Build quality was considered solid for the price, with reviewers calling it well made and modern enough despite the older design.

The Watch 9 feels premium and well built despite using aluminum rather than the Ultra's more rugged materials. Its finish and everyday construction earn strong marks.

Fit evidence was limited and mixed, with one reviewer saying the older body did not sit as flush as the Series 11.

The slim case generally fits wrists well and stays unobtrusive, especially for sleep. Strap sizing can be less forgiving, with some users landing between holes or at the edge of a supplied size.

Water resistance was considered adequate for common needs, with several reviewers accepting the 50m/swimproof rating.

IP68 and 5ATM protection make the Watch 9 well suited to showers, rain, and swimming. It lacks the deeper diving credentials of the Ultra models, but everyday water resistance is strong.

Size options were viewed positively for offering 40mm and 44mm choices, especially for smaller wrists.

The 40mm and 44mm choices make it easier to balance wrist fit, screen size, and battery capacity. Reviewers see real value in having both rather than a single oversized model.

Durability was mixed: stronger Ion-X glass drew praise, but some reviewers noted weaker dust/scratch protection or actual scratching.

Sapphire glass, IP68, 5ATM, and military-grade ratings give the Watch 9 solid everyday toughness. It is less rugged than the Ultra line, but testers generally trust it for workouts, swimming, showers, and normal outdoor use.

Style and design were the main aesthetic tradeoff: reviewers liked the familiar Apple Watch look but repeatedly called it dated or bezel-heavy.

The thin, minimal body and premium finish win many fans, but the circle-on-squircle look remains divisive. Some grow to like it while others still prefer Samsung's older fully round design.

Display quality was a major upgrade thanks to always-on functionality, though reviewers still noted smaller bezels and lower specs than Series models.

Display quality is a major strength: sharp, vibrant, responsive, and premium-looking across sizes. Reviewers repeatedly describe the AMOLED panel as excellent even though it changes little from the Watch 8.

Outdoor visibility was generally serviceable, but direct sunlight remained a repeated display limitation.

Outdoor visibility is excellent. The 3,000-nit AMOLED remains easy to read in direct sun, during workouts, and from awkward angles with very few complaints.

Brightness was usually adequate and sometimes praised, but reviewers acknowledged it is below the brighter Series and Ultra screens.

The 3,000-nit panel is consistently praised as bright enough for outdoor use. Even reviewers comparing it with brighter Ultra hardware generally consider the Watch 9's brightness more than sufficient.

Reliability evidence was limited but positive, with one reviewer concluding the SE 3 has what most users need.

Reliability concerns center on charging behavior and isolated software freezes. Most daily operation is stable, but charging inconsistency is serious enough to lower confidence for some testers.

Value for money was the strongest consensus attribute, with reviewers repeatedly calling the SE 3 a standout bargain or best-value Apple Watch.

Value depends heavily on what you already own and current street pricing. First-time buyers and older-watch upgraders see a strong package, while Watch 8 owners are repeatedly told the modest changes do not justify full price.

Navigation evidence was limited but positive, with offline Apple Maps presented as helpful when away from the phone.

Navigation is functional but not athlete-leading. One sports-focused review specifically cites navigation among the areas that still lag dedicated training watches.

The companion app setup drew a mixed note because managing Watch, Health, and Fitness across multiple iPhone apps can feel tedious.

Samsung Health's redesign is widely praised for cleaner organization, customizable views, and better presentation of health data. The main complaint is setup friction when enabling the many advanced metrics.

Button and gesture controls were widely praised, especially Double Tap, Wrist Flick, the Digital Crown, and side-button shortcuts.

Physical controls are mixed. Accidental presses appear improved, but workout interaction can feel clunky and some reviewers still prefer more dedicated hardware controls.

Customization was useful through watch faces, workout views, and settings, but limited by the lack of third-party watch faces.

Customization is extensive, spanning tiles, watch faces, complications, app layouts, colors, and shortcuts. Reviewers consistently appreciate how much can be tailored on-watch or from the phone.

On-device Siri was broadly seen as a useful upgrade, making commands faster and more practical for workouts, timers, weather, and health questions.

Gemini is one of the Watch 9's best smart features, with fast responses and useful hands-free Raise to Talk access. Occasional gesture misses keep it from being flawless.

Apple Pay was positively mentioned as part of the compelling smartwatch feature set and deep Apple ecosystem integration.

Samsung Wallet payments are described as seamless and convenient, making wrist-based NFC purchases a useful everyday feature.

Menu navigation evidence was limited but positive, with one reviewer describing the basic home-screen and control flow as simple.

Samsung's menu structure is praised as intuitive and well organized, with important functions usually only a swipe or two away.

Pairing/setup evidence was limited but positive, with one review calling setup quick and easy.

Samsung-to-Samsung setup is clean and well integrated, with the phone automatically handling much of the companion software setup.

The user interface was praised as easy, cohesive, and fluid, with gestures and Smart Stack improving quick interactions.

One UI 9 Watch is widely praised as easy to navigate, well organized, and highly customizable. Tile stacks and gesture navigation help surface dense information without making the watch feel overwhelming.

Notification handling was a major everyday strength, with reviewers praising call, text, and response convenience from the wrist.

Notifications are a strong everyday feature, arriving reliably from a wide range of phone apps and helping users leave the phone in a pocket more often.

Software smoothness was one of the most consistent strengths, with reviewers praising the S10 chip for snappy menus, fast apps, and fluid navigation.

Performance is one of the biggest upgrades. Apps open quickly, scrolling is fluid, and the Snapdragon Wear Elite removes many of the tiny pauses that made older Galaxy Watches feel less polished.

Reviewers generally agreed the SE 3 delivers the core Apple Watch experience, making it feel much less like a compromised budget model.

The Watch 9 handles core smartwatch jobs—calls, notifications, apps, smart-home control, and assistant tasks—very well. Reviewers repeatedly describe it as a complete everyday smartwatch.

Third-party app support was praised for extending the native experience, with reviewers highlighting Apple’s App Store depth and useful fitness apps.

Third-party app support is excellent, with popular fitness, audio, navigation, and productivity apps available through Wear OS. That breadth is a major advantage over simpler fitness-first wearables.

Watch faces were viewed positively, especially the always-on versions and Apple’s high-quality built-in choices.

Watch faces offer strong customization and useful information density, and several reviewers like the new defaults. One reviewer dislikes Samsung's visual style overall, so aesthetics remain personal.

The app ecosystem was one of the SE 3’s strongest advantages, repeatedly described as unmatched or far richer than competing budget watches.

Wear OS gives the Watch 9 a strong app selection, and tested Google and third-party apps generally run smoothly. This helps it feel like a full smartwatch rather than only a fitness tracker.

Call handling was rated highly where tested, especially voice isolation and gesture-based call management.

On-wrist calls are useful for short conversations and moments when reaching for a phone is inconvenient. LTE versions add more independence when away from the phone.

watchOS experience received very strong marks for polish, smoothness, and making the SE 3 feel similar to pricier Apple Watches.

Wear OS 7 with One UI 9 Watch is consistently praised as polished, mature, and pleasant to use. Samsung's refinements give the watch a strong everyday software experience.

Touchscreen responsiveness had limited but very positive evidence, with PCMag saying the watch responded promptly and consistently.

Touch input is consistently responsive, including swipes, typing, and the digital bezel. Reviewers report precise interaction even on the compact display.

Cellular connectivity was viewed as a useful option, with 5G improving coverage, efficiency, and phone-free use for calls, messages, and downloads.

LTE adds real phone-free usefulness for calls and data, but it also increases battery drain. That tradeoff matters most on a watch whose endurance is already limited.

Safety features were strongly praised, especially fall detection, crash detection, emergency features, and real family anecdotes.

Hearing-exposure alerts are a useful addition for concerts and loud environments, but not everyone sees a regular use case. The Watch 9 also lacks some emergency health features available on certain rivals.

Auto-detection was useful but not flawless; reviewers found it adequate for walks and workouts, while one later review said it still lagged rivals.

Automatic workout detection is a standout strength, reliably picking up walks and even swims without manual starts. Multiple testers praised how little intervention it needs.

Cross-platform compatibility was a clear limitation because the SE 3 remains an iPhone-only smartwatch.

The Watch 9 works broadly with Android, but important health and syncing features remain locked to Galaxy phones. That restriction is a repeated frustration for Pixel, OnePlus, and other Android users.

ECG was the most repeated missing health feature, often framed as the main reason some higher-risk buyers might step up to the Series line.

ECG is useful as part of Samsung's broad health suite, but its Galaxy-phone requirement sharply limits access for users of other Android brands.

The Antioxidant Index draws mixed reactions. Some see dietary context in the beta-carotene estimate, while others find it of limited practical use.

The vibration motor is criticized as too weak, continuing a complaint from the previous generation and making alerts easier to miss.

Bluetooth 6 is viewed as a meaningful upgrade because it can extend useful distance from the phone while improving efficiency.

Music controls and speaker/media features were useful additions, though reviewers were split on how often they would actually use playback from the watch speaker.

The 32GB storage is enough for several offline Spotify playlists, making phone-free listening practical even though capacity trails some rivals.

Fitness Index and other health scores can summarize complex data well, especially for strengths and weaknesses. At the same time, the growing number of scores can feel unfocused or overwhelming.

Step counting has a recurring false-step problem. Multiple testers report extra steps while driving or small overcounts in manual tests, making this one of the weaker basic fitness metrics.
