Apple Watch SE 3 vs Garmin Venu 3

Apple Watch SE 3

The big SE 3 story: an always-on display, a first for the SE line. The LTPO OLED panel peaks at 1,000 nits — bright enough for everyday use, but half the Series 11's 2,000 nits and a third of the Ultra 3's 3,000.

• Always-on display arrives on the SE for the first time — Origin Disc: 'that alone is a huge upgrade for the SE line.'
• LTPO OLED panel peaks at 1,000 nits — fine for everyday use but dimmer than rivals.
• 1,000 nits is half the Series 11's 2,000 and a third of the Ultra 3's 3,000 — the SE 3's display is its clearest hardware compromise.
• Always-on is a personal-preference feature — some owners prefer to leave it off for extra battery life.

Garmin Venu 3

1.4-inch AMOLED on the Venu 3, 1.2-inch on the Venu 3S. Bright, vibrant, sharp. Always-on display supported. Gorilla Glass 3 protection.

• 1.4-inch AMOLED (Venu 3) — bright, vibrant, sharp. The smaller Venu 3S uses a 1.2-inch panel.
• Always-on display supported — informative without raising the wrist, with manageable battery cost.
• AMOLED is a highlight of the Venu line — vibrant colors set it apart from Garmin's transflective-display models.
• Gorilla Glass 3 protection — standard scratch resistance for the price tier.
• Readable in daylight — adequate brightness for outdoor workouts, though not the 3,000-nit level of Apple/Samsung flagships.

Apple Watch SE 3

Heart rate is the SE 3's standout — testers rate it among the best wrist sensors available. Apple adds nightly wrist-temperature tracking and sleep apnea notifications. But ECG, blood oxygen (SpO2), and the Series 11's new hypertension alerts are all absent, and sleep-stage data underreports deep sleep.

• Heart-rate accuracy is excellent — Mike O'Brien tested it against a Polar H10 ECG chest strap and found it had the second-highest correlation of the watches tested, behind only the Pixel Watch 3.
• The Quantified Scientist rates the Apple Watch's optical heart-rate sensor as the best wrist HR monitor he has tested — the SE 3 inherits it.
• No ECG sensor — confirmed missing; if heart-rhythm ECG matters to you, you need the Series 11 or Ultra 3.
• No blood-oxygen (SpO2) sensor and no hypertension notifications — the Series 11's headline health features are absent.
• Apple adds nightly wrist-temperature tracking — the watch samples skin temperature roughly every 5 seconds overnight.
• Sleep apnea notifications are now included — a useful screening feature given how many people have undiagnosed sleep apnea.
• Sleep-stage tracking underreports deep sleep — Mike O'Brien recorded 45-55 minutes of deep sleep per night while reference devices showed 1.5-2.5 hours.

Garmin Venu 3

Elevate Gen 4 optical HR, SpO2, ECG, HRV Status, skin temperature, Body Battery, Sleep Coach, nap detection. The Venu 3's wellness suite is the deepest in any Garmin — a genuine Oura/Whoop alternative.

• Trusted Reviews: 'the best interpretation of wellness data I've seen on a Garmin so far, and a great alternative to Oura and Whoop.'
• ECG app — available on the Venu 3 (set up via the Garmin Connect app); a clinical-grade health feature.
• Sleep Coach + nap detection — Garmin's most advanced sleep features; nap detection was new to the Venu 3.
• Body Battery + HRV Status + skin temperature — Garmin's full wellness + recovery analytics suite.
• Elevate Gen 4 optical HR — reliable for steady-state; like all wrist optical HR, less accurate than a chest strap for intervals.

Apple Watch SE 3

The full watchOS workout app, activity rings, automatic workout detection, and built-in GPS. Apple rates about 7 hours of GPS workout tracking. It is not a dedicated running watch — no dual-frequency GPS — but for everyday fitness it covers the essentials well.

• Full watchOS workout app, activity rings and automatic workout detection — everything expected of an Apple Watch.
• Built-in GPS rated for about 7 hours of workout tracking — DesFit found real-world endurance well beyond that claim.
• The Quantified Scientist rates the Apple Watch SE as a pretty good GPS tracker — accurate enough for everyday runs and rides.
• Not a dedicated running watch — no dual-frequency GPS and no deep training analytics; serious runners still look to Garmin or the Ultra 3.
• Crash detection, fall detection and Emergency SOS carry over — Mike O'Brien notes fall detection is 'among the best in the industry.'

Garmin Venu 3

80+ sport profiles + Garmin's training analytics + Morning Report + meditation/breathwork. Capable for everyday fitness; serious athletes still want the Forerunner/Fenix depth and maps.

• 80+ sport profiles — DC Rainmaker confirms 'roughly 80 sport profiles' shared across Garmin's sub-$1,000 lineup.
• New wheelchair mode — accessibility-focused activity tracking; counts pushes instead of steps.
• Morning Report + daily suggested workouts — Garmin's coaching guidance, tuned toward everyday fitness rather than hardcore performance.
• Meditation + breathwork activities — wellness-focused features that fit the Venu 3's everyday-health positioning.
• 5 ATM water resistance — pool + open-water swim tracking supported.

Apple Watch SE 3

Apple still rates the SE 3 at 18 hours of all-day battery, and that conservative number holds — but independent endurance tests stretched it to 37-41 hours of continuous wear depending on size. The genuine upgrade is fast charging: roughly 0-80% in 45 minutes, with a 15-minute top-up buying about 8 hours. A low-power mode reaches ~32 hours.

• Fast charging is new to the SE line — about 0-80% in 45 minutes, matching Apple's claim in testing.
• A 15-minute top-up buys roughly 8 hours of use — enough to rescue a sleep-tracking night.
• Endurance test: the 44mm SE 3 ran ~41 hours of continuous wear and the 40mm ~37-38 hours — far beyond Apple's conservative 18-hour rating.
• Still rated 18 hours — fast charging helps, but daily charging is the reality, and you may need a pre-bed top-up for sleep tracking.
• A low-power mode extends life to roughly 32 hours on a single charge.

Garmin Venu 3

Up to 14 days smartwatch mode on the Venu 3 (~10 days on the smaller 3S). Garmin's signature multi-week battery — Trusted Reviews calls it 'set-and-forget.'

• Up to 14 days smartwatch mode (Venu 3) — Trusted Reviews: 'a true set-and-forget smartwatch that can go the distance.'
• ~10 days on the smaller Venu 3S — still multi-week-class for a compact watch.
• The Verge notes Garmin watches 'last weeks on a single charge' — a core advantage over Apple/Samsung.
• Proprietary Garmin USB-C charging cable — no Qi wireless charging.
• AOD on reduces battery noticeably — but even with always-on enabled, multi-day life is comfortably retained.

Apple Watch SE 3

watchOS 26 on Apple's S10 chip — identical core performance to the Series 11 and Ultra 3, including double-tap and wrist-flick gestures. 64GB of storage. Apple Pay, the App Store and the full ecosystem are all here. The one hard limit: it works only with an iPhone.

• Same S10 chip as the Series 11 and Ultra 3 — TheJuan&Only confirms identical core performance across the lineup.
• Supports the S10-enabled gestures — double-tap and wrist-flick to dismiss notifications.
• 64GB of storage and the full App Store, Apple Pay, Find My and Siri — nothing core is cut from the experience.
• iPhone-only — like every Apple Watch, the SE 3 does not work with Android phones.
• TechRadar: it has 'the same fantastic chipset as the Ultra 3 and Series 11' — the SE 3 doesn't feel slow or cut-down in daily use.

Garmin Venu 3

Garmin OS + Garmin Connect + Connect IQ store. Built-in speaker + microphone for voice calls and a voice assistant. Garmin Pay. Works with iOS + Android.

• Built-in speaker + microphone — on-watch voice calls (via a connected phone) and a voice assistant; a notable Venu 3 addition.
• Garmin OS + Connect IQ store — apps, watch faces, data fields.
• Android Authority notes Garmin's app catalog is thinner than Wear OS — 'Garmin makes the best smartwatches that I can't wear every day,' partly an app-ecosystem critique.
• Garmin Pay — contactless payments via NFC.
• Works with both iOS and Android — cross-platform, unlike Apple Watch or Galaxy Watch.

Apple Watch SE 3

Crack-resistant Ion-X glass, now rated about 4x tougher than the SE 2, over an aluminum case. Water resistance is 50m (5 ATM) — fine for pool and open-water swimming.

• 50m (5 ATM) water resistance — rated for pool and open-water swimming.
• Crack-resistant Ion-X glass, now about 4x more crack- and scratch-resistant than the SE 2.
• DesFit notes Apple Watch aluminum models hold up well in practice — he has scratched only one across many Apple Watches going back to the Series 3.
• Not as scratch-hardened as the Series 11's ceramic-coated glass or the Ultra 3's sapphire — fine for everyday wear, not adventure abuse.

Garmin Venu 3

5 ATM (50m) water resistance. Gorilla Glass 3 + metal bezel. Fiber-reinforced polymer case. Durable for everyday wear and swim tracking — not adventure-rated like the Fenix.

• 5 ATM (50m static) water resistance — pool + open-water swim rated.
• Gorilla Glass 3 + metal bezel — standard durability for the price tier.
• Fiber-reinforced polymer case — lightweight and durable for everyday and overnight wear.
• Not adventure-rated like the Fenix — no MIL-STD certification; this is a wellness watch, not an expedition tool.

Apple Watch SE 3

Built-in GPS, Apple Pay via NFC, Bluetooth and Wi-Fi. An optional cellular model adds standalone connectivity for about $50 more. The SE 3 lacks the Series 11's second-generation ultra-wideband chip, so it can only ping a lost iPhone rather than guide you to it.

• Built-in GPS, Apple Pay (NFC), Bluetooth and Wi-Fi — the standard Apple Watch connectivity set.
• An optional cellular model adds standalone connectivity for roughly $50 more — useful for leaving the phone behind.
• No second-generation ultra-wideband chip — the SE 3 can only beep a lost iPhone, not precision-guide you to it like the Series 11.

Garmin Venu 3

Single-frequency GPS, NFC for Garmin Pay, Bluetooth, ANT+, Wi-Fi. No LTE, no on-watch maps. Phone required for connectivity and the voice features.

• Single-frequency GPS — accurate for everyday tracking; not the multi-band precision of the Forerunner/Fenix tiers.
• No on-watch maps — the Venu line has never had mapping; for navigation, step up to a Forerunner or Fenix.
• ANT+ + Bluetooth — pair chest straps, footpods, and cycling sensors.
• NFC for Garmin Pay + Wi-Fi for sync.
• No LTE — phone required for connectivity; voice calls route through the connected phone.

Apple Watch SE 3

At a held-steady $249, the SE 3 is the cheapest way into a current Apple Watch and the obvious pick for most iPhone owners. The $399 Series 11 adds ECG, blood oxygen, hypertension alerts, a brighter screen and 24-hour battery; the $799 Ultra 3 adds far more. For the majority, the SE 3's gaps will not be felt.

• TechRadar's verdict: the SE 3 'might be the best-value Apple Watch ever made.'
• Mike O'Brien calls it 'the best Apple Watch for most people' — major improvements with very few noticeable differences from the $400 Series 11.
• Gizmodo: 'The Apple Watch SE 3 is a stupidly good value for $250.'
• Step up to the $399 Series 11 for ECG, blood oxygen, hypertension alerts, a 2,000-nit screen and 24-hour battery — worth it only if you actually need those.
• Best for: first-time Apple Watch buyers and anyone who wants the core experience for the lowest price — Tom's Guide names the SE 3 'the best value, great for first-time users.'

Garmin Venu 3

$449.99 launch, now widely discounted (Trusted Reviews documented £299). Competes with the Apple Watch, Galaxy Watch, Pixel Watch, and Oura/Whoop for wellness tracking.

• $449.99 launch price — now widely discounted; Trusted Reviews documented a £299 price.
• Trusted Reviews: 'one of the few smartwatches that we can genuinely recommend to everyone.'
• vs Oura / Whoop: the Venu 3 is a one-time purchase with no subscription — Trusted Reviews calls it 'a great alternative to Oura and Whoop.'
• vs Apple Watch / Galaxy Watch / Pixel Watch: Garmin wins on battery (14 days vs 1-2 days) + wellness depth; the others win on app ecosystem + LTE + smartwatch polish.
• Best for: anyone who wants Garmin's best wellness + sleep tracking with multi-week battery, voice calls, and an AMOLED screen — and doesn't need maps or hardcore training analytics.
