Apple Watch SE 3 vs Suunto Race

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.

Suunto Race

1.43-inch AMOLED, 466×466 resolution, 1,000 nits brightness. Sapphire crystal (titanium model). Beautiful screen — but the always-on wake transition is the slowest DC Rainmaker has measured.

• 1.43-inch AMOLED, 466×466 resolution — sharp, vibrant display.
• 1,000 nits brightness — DC Rainmaker: 'essentially the same display brightness as other endurance-focused watches by Garmin and Polar.'
• Always-on wake delay — DC Rainmaker: '~2.5 seconds, easily the slowest transition from dimmed state to full brightness of any AMOLED watch I have.'
• Dimmer than Apple/Samsung 3,000-nit flagships — but DC Rainmaker questions whether ultra-bright displays genuinely benefit endurance watches.
• the5krunner praised the screen as 'this beautiful' — display quality is a genuine highlight despite the wake-delay flaw.

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.

Suunto Race

Optical HR, SpO2 (blood oxygen), sleep tracking, stress + recovery. No ECG. Suunto's sensor suite covers training essentials; this is a sports watch, not a clinical-health smartwatch.

• Optical HR — reliable for steady-state training; like all wrist optical HR, less accurate than a chest strap for intervals.
• SpO2 (blood oxygen) — on-demand readings, useful for altitude acclimatization on trail and mountain adventures.
• Sleep tracking + stress + recovery metrics — feeds Suunto's training-readiness guidance.
• No ECG — this is a sports watch, not a clinical-health smartwatch. No advanced cardiac sensors.
• Heart-rate-based training metrics — training load, recovery time, and VO2-max-style fitness estimates.

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.'

Suunto Race

95+ sport modes + training-load and recovery analytics + free offline topographic maps + breadcrumb navigation. Strong for runners, hikers, and trail athletes.

• 95+ sport modes — broad activity coverage including running, trail, cycling, swimming, hiking.
• Free offline topographic maps — full maps loaded onto the watch at no extra cost; a key value advantage.
• Training-load + recovery analytics — Suunto's coaching engine guides training intensity and rest.
• Breadcrumb route navigation + turn-by-turn — strong for trail running and hiking on unfamiliar routes.
• Suunto's training software is less deep than Garmin Connect — adequate guidance but fewer advanced analytics.

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.

Suunto Race

~12 days smartwatch use, ~40 hours dual-band GPS, ~120 hours in tour (low-power) GPS mode. Excellent endurance — multi-day adventure tracking without recharge.

• ~12 days smartwatch-mode battery — multi-week-class endurance, no daily-charge anxiety.
• ~40 hours dual-band GPS — supports ultramarathon and multi-day adventure tracking.
• ~120 hours tour (low-power) GPS mode — extended battery for the longest expeditions.
• Proprietary Suunto magnetic charging clip — no Qi wireless charging.
• Battery endurance is a core strength — comparable to Garmin endurance watches at a lower price.

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.

Suunto Race

Suunto OS + Suunto app. Works with iOS + Android. Strava + TrainingPeaks + Komoot integration. No NFC payments. Ecosystem is smaller and less mature than Garmin Connect.

• Suunto OS + Suunto app — works with both iOS and Android; cross-platform.
• Strava + TrainingPeaks + Komoot integration — syncs with the major third-party fitness platforms.
• Suunto's ecosystem is smaller and less mature than Garmin Connect — fewer apps, less training-analytics depth.
• No NFC contactless payments — no on-watch wallet.
• Suunto has improved software steadily post-launch — the5krunner noted it has fixed key flaws of the previous generation.

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.

Suunto Race

5 ATM (50m) water resistance. Sapphire crystal on the titanium model, Gorilla Glass on steel. Titanium or stainless steel case. Built for trail and adventure abuse.

• 5 ATM (50m static) water resistance — pool + open-water swim rated.
• Sapphire crystal on the titanium model — highly scratch-resistant; the steel model uses Gorilla Glass.
• Titanium or stainless steel case — durable build for trail and adventure use.
• Suunto's heritage is outdoor/adventure watches — the Race is built to take trail abuse.

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.

Suunto Race

Dual-band GPS, free offline maps, Bluetooth. No LTE, no NFC payments, no Wi-Fi. Phone required for connectivity.

• Dual-band GPS — accurate tracking in urban canyons + dense tree cover.
• Free offline topographic maps — loaded onto the watch via the Suunto app at no extra cost.
• Bluetooth for sensor pairing — chest straps, footpods, cycling sensors.
• No LTE — phone required for connectivity; no standalone calls or texts.
• No NFC payments, no Wi-Fi — minimal smartwatch connectivity; this is a focused sports watch.

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.'

Suunto Race

$449 launch — disruptive pricing that undercut comparable Garmin AMOLED watches by $150+. Competes with the Garmin Forerunner 265/965, Polar, and Coros.

• $449 launch price — DC Rainmaker: 'Suunto has absolutely slaughtered the competition on price here.'
• DC Rainmaker called it 'the best Suunto yet' — a genuine return to form.
• vs Garmin Forerunner 965: Race wins on price + digital crown + free maps; Garmin wins on training-science depth + app ecosystem + brighter consistency.
• Suunto becoming 'one of the best bang-for-your-buck smartwatches' — Triathlete's read on the brand's value positioning.
• Best for: runners, hikers, and trail athletes who want Garmin-tier endurance hardware with AMOLED + free maps + a digital crown at a genuinely lower price, and don't need smartwatch features.
