Apple Watch SE 3 vs Garmin Forerunner 965

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 Forerunner 965

1.4-inch AMOLED, 454×454 resolution — nearly 4× the resolution of the Forerunner 955's memory-in-pixel panel. Always-on display. Vibrant, sharp, and readable in sunlight.

• 1.4-inch 454×454 AMOLED — DC Rainmaker: 'they've increased the resolution by almost 4X' over the 955's MIP panel.
• The Verge: 'For once, there's practically no tradeoff between an always-on OLED display and long battery life.'
• Garmin eschewed the MIP panel for AMOLED — Notebookcheck confirms the 965 is AMOLED, a shift from the 955's transflective display.
• Always-on display supported — vibrant and readable in direct sunlight without significant battery penalty.
• Larger display improves on-watch map readability + data-field density vs the smaller Forerunner 265.

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 Forerunner 965

Elevate Gen 4 optical HR, SpO2, HRV Status, sleep tracking, Body Battery, stress tracking, Morning Report. No ECG. Garmin's analytics suite is the strength; raw HR accuracy lags chest straps for intervals.

• Elevate Gen 4 optical HR — reliable for steady-state; like all wrist optical HR, less accurate than a chest strap for intervals.
• HRV Status — overnight heart-rate-variability tracking feeds Training Readiness + recovery insights.
• Body Battery + stress tracking + sleep tracking + Morning Report — Garmin's full daily-wellness suite.
• No ECG — the5krunner explicitly notes the 965 lacks the ECG feature found on other Garmin watches.
• SpO2 (pulse ox) — on-demand + spot-check; useful for altitude acclimatization.

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 Forerunner 965

Garmin's deepest training-science suite — Training Readiness, Acute/Chronic Load ratio, Training Status, wrist running power, Run Dynamics, race predictor, PacePro, daily suggested workouts. The serious-athlete benchmark.

• Training Readiness + Acute/Chronic Load ratio — DC Rainmaker: 'takes your Acute Load, the short-term load, in comparison to your Chronic Load, your 28-day load' for science-backed training guidance.
• Wrist-based running power + Run Dynamics — vertical oscillation, ground contact time, stride length, all without a chest strap or footpod.
• Daily suggested workouts + PacePro + race predictor — Garmin's coaching engine; among the deepest in any smartwatch.
• Triathlon + multisport modes — open-water swim, brick workouts, transitions; a genuine triathlon training tool.
• 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 Forerunner 965

~23 days smartwatch mode, ~31 hours all-systems GPS. Garmin's signature multi-week battery — no daily-charge anxiety. Proprietary USB-C charging cable (no Qi, no solar).

• ~23 days smartwatch mode — Garmin's signature multi-week battery; far beyond Apple Watch Ultra or Galaxy Watch.
• ~31 hours all-systems GPS — multi-day ultra and adventure tracking without recharge.
• No solar charging — the5krunner notes the 965 lacks the solar option found on Fenix-tier Garmins.
• No Qi wireless charging — proprietary Garmin USB-C cable only.
• Reddit users cite the multi-week battery as a defining advantage — no charging cable to pack on trips.

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 Forerunner 965

Garmin OS + Garmin Connect app + Connect IQ store for apps/watch faces. Garmin Pay. No speaker/mic, no voice assistant. Works with iOS + Android. Frequent firmware updates.

• Garmin OS + Connect IQ store — apps, watch faces, data fields. Not Wear OS, but a mature ecosystem.
• Garmin Connect app — universally praised for training analytics depth, frequently criticized for app-UI polish.
• Frequent firmware updates — Notebookcheck documented 'nearly 30 bug fixes, improvements and new features in first beta update.'
• No speaker/microphone — the5krunner notes no on-watch voice calls or assistant.
• Works with both iOS and Android — cross-platform, unlike Apple Watch or Galaxy Watch.
• Garmin Pay — contactless payments via NFC.

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 Forerunner 965

5 ATM water resistance. Titanium bezel + Gorilla Glass 3 (no sapphire). Fiber-reinforced polymer case. Built for daily training abuse — but the glass is the weak point.

• 5 ATM (50m static) water resistance — pool + open-water swim rated.
• Titanium bezel — protects the toughened display + adds structural integrity.
• Gorilla Glass 3 — the weak point. No sapphire option at the $599 price; the5krunner reports scratch concerns.
• Fiber-reinforced polymer case — lightweight and durable for daily training.

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 Forerunner 965

Multi-band (dual-frequency) GPS, full-color TopoActive maps, NFC for Garmin Pay, Bluetooth, ANT+, Wi-Fi. No LTE — phone required for connectivity.

• Multi-band (dual-frequency) GPS — accurate tracking in urban canyons + dense tree cover.
• Full-color TopoActive maps — on-watch mapping + turn-by-turn navigation, a key 965-vs-265 differentiator.
• ANT+ + Bluetooth — pair chest straps, footpods, power meters, cycling sensors.
• NFC for Garmin Pay + Wi-Fi for sync.
• No LTE — the5krunner notes the 965 lacks cellular; phone required for connectivity.

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 Forerunner 965

$599 launch — premium running-watch tier. Competes with the cheaper Forerunner 265, the Fenix-tier Garmins, and the Apple Watch Ultra 2. Ages well and discounts over time.

• $599 launch price — the5krunner: 'disconcertingly high,' especially given no sapphire glass.
• Discounts well over time — T3: 'Garmin's best-selling Forerunner 965 watch has been discounted to its lowest-ever price.'
• vs Forerunner 265 (£429): the 265 is the cheaper AMOLED sibling. The 965 adds maps, the larger display, and the titanium bezel.
• Garmin watches age very well — Wired: 'even though Garmin watches are costly, they age very well' and hold value.
• vs Apple Watch Ultra 2: Garmin wins on battery + training depth; Apple wins on smart features, LTE, ECG, and ecosystem (for iPhone owners).
