Apple Watch SE 3 vs Google Pixel Watch 2

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.

Google Pixel Watch 2

1.2-inch AMOLED with the domed-glass cover, 320 PPI, always-on display. Sharp and vibrant — though small and lower-brightness compared to later Pixel Watches.

• 1.2-inch AMOLED at 320 PPI — sharp and vibrant, sitting under the signature domed glass.
• Always-on display supported — and now actually usable thanks to the Pixel Watch 2's improved battery.
• Domed-glass cover — Wired praises the domed glass + display combination; a Pixel Watch signature.
• Smaller display than later Pixel Watches — the Pixel Watch 3 added 40% more usable screen space on the 45mm.
• Lower peak brightness than the Pixel Watch 3 (2,000 nits) and Pixel Watch 4 (3,000 nits) — adequate but not class-leading.

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.

Google Pixel Watch 2

New multi-path optical HR sensor, cEDA continuous stress tracking, skin temperature, ECG, SpO2, Fitbit-powered sleep + readiness. A notable sensor upgrade over the original Pixel Watch.

• New multi-path optical heart-rate sensor — Fitbit's improved HR tech, a meaningful accuracy upgrade over the original Pixel Watch.
• cEDA (continuous electrodermal activity) sensor — powers the Body Response feature for continuous stress tracking.
• Skin temperature sensor — overnight temperature tracking for sleep and cycle insights.
• ECG + SpO2 + Fitbit sleep tracking + Daily Readiness — the full Fitbit health suite on the wrist.
• Best Fitbit health analytics (Daily Readiness, advanced sleep insights) gated behind a Fitbit Premium subscription.

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.'

Google Pixel Watch 2

Fitbit-powered workout tracking — heart-rate zones, Active Zone Minutes, pace + distance, auto-detection. Solid for everyday fitness; serious athletes still lean Garmin.

• Fitbit-powered workout tracking — heart-rate zones, Active Zone Minutes, pace, distance, and route mapping.
• Heart-rate-zone coaching — real-time pacing feedback during workouts via the improved HR sensor.
• Automatic workout detection — catches walks, runs, and cycling without manual start.
• Built-in GPS — standalone outdoor activity tracking without the phone.
• 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.

Google Pixel Watch 2

A full 24 hours with the always-on display on — the fix for the original Pixel Watch's defining flaw. Fast charging. Still requires daily charging.

• 24 hours with the always-on display enabled — the headline fix; the original Pixel Watch couldn't reliably last a day with AOD on.
• Android Authority's retrospective on the original Pixel Watch: battery was 'my biggest issue' — the Pixel Watch 2 directly addresses it.
• Snapdragon W5 chip — the efficiency gain that made the 24-hour battery possible.
• Fast charging — a quick top-up before bed enables overnight sleep tracking.
• Still requires daily charging — a real improvement over the original Pixel Watch, but far from Garmin's multi-week endurance.

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.

Google Pixel Watch 2

Wear OS with Fitbit integration, Google Assistant, Google Wallet, Google Maps, full Play Store. Tight Pixel-phone integration. Android-only.

• Wear OS — full Play Store, Google Wallet, Google Maps, Spotify; the most complete Wear OS experience at launch.
• Deep Fitbit integration — Fitbit health tracking is the Pixel Watch's analytics backbone.
• Google Assistant on the wrist — voice queries, reminders, smart-home control.
• Tight integration with Pixel phones — the Pixel Watch 2 is best paired with a Pixel, though it works with any Android phone.
• Android-only — no iOS compatibility.

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.

Google Pixel Watch 2

5 ATM (50m) water resistance + IP68 dust/water. Gorilla Glass 5 domed cover (no sapphire). Recycled-aluminum case. Durable for everyday wear.

• 5 ATM (50m static) water resistance + IP68 dust/water rating — pool + open-water swim rated.
• Gorilla Glass 5 domed cover — no sapphire crystal; standard scratch resistance for the price.
• Recycled-aluminum case — durable and light for everyday wear.
• Sealed case — not repairable like the later Pixel Watch 4; a damaged unit means a replacement.

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.

Google Pixel Watch 2

Built-in GPS, optional LTE, NFC for Google Wallet, Bluetooth 5.0, Wi-Fi. No multi-band GPS, no satellite messaging.

• Built-in GPS — standalone outdoor tracking; single-frequency (multi-band arrived on later Pixel Watches).
• Optional LTE — standalone calls, texts, and music streaming without the phone.
• NFC for Google Wallet — contactless payments.
• Bluetooth 5.0 + Wi-Fi — standard Wear OS connectivity stack.
• No satellite messaging — that arrived on the Pixel Watch 4.

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.'

Google Pixel Watch 2

$349 launch (41mm). Now superseded by the Pixel Watch 3 + 4 — a strong value if discounted. Competes with the Galaxy Watch and (for iOS) the Apple Watch Series 9.

• $349 launch price (41mm) — standard premium-Android-smartwatch pricing.
• Now superseded by the Pixel Watch 3 (bigger screen) and Pixel Watch 4 (repairable, 3,000 nits) — a strong value if discounted.
• vs Apple Watch Series 9: different platforms — the Pixel Watch 2 is the Android flagship, the Series 9 the iOS one.
• vs Samsung Galaxy Watch 6: both run Wear OS; Samsung offers more sizes, Pixel offers tighter Fitbit + Pixel-phone integration.
• Best for: Android users (especially Pixel-phone owners) who want the Pixel Watch design with a battery that lasts the day — and find the Pixel Watch 2 discounted now that newer models exist.
