Apple Watch Series 10
Best for: Existing owners, discounted-stock buyers comparing against current models
Discontinued — Apple's current lineup is Series 12, Ultra 4 and SE 3. Still the strongest sleep-tracking smartwatch for iPhone users if you find remaining stock, but buy a current Apple Watch instead unless the discount is steep.
We'd skipOne of the higher prices in the tracker category for the second-lowest sleep score - it is a great watch that sleeps poorly, and the battery will not survive the night plus the day.Apple's former flagship, discontinued and no longer in Apple's lineup, which now lists Series 12, Ultra 4 and SE 3. Series 10 introduced sleep apnea detection (supported on Series 9+, launched 2024), refined sleep stages, and a larger always-on display. iOS-only. Battery is the constraint at ~18 hours — you'll charge before sleep every day. Apple no longer sells it directly; remaining units are third-party stock. Treat this page as a reference for owners and for anyone weighing discounted stock against current Apple Watch models — not as a buying recommendation.

Editor's deep dive
Is the Apple Watch Series worth it?
The short answer
The Apple Watch Series 10 is discontinued — Apple's watch lineup now lists Series 12, Ultra 4 and SE 3, and the Series 10 product page redirects to Apple's watch index. If you are buying new, choose a current model. This page remains useful in two situations: you already own a Series 10, or you have found discounted remaining stock and want to know what you would be getting. On the merits, it is the right sleep tracker for iOS users who want one device for everything (notifications, fitness, sleep, payment) rather than best-in-class sleep tracking specifically. FDA-cleared sleep apnea detection (2024) is a real differentiator no competitor has. The ~18h battery and watch-on-wrist comfort are the two limits keeping it behind Oura and Whoop on sleep specifically.
Who it's for
iOS users who want one device for everything — notifications, fitness, sleep, contactless pay, the rest. Apple Watch is the practical default if you already wear one. If you don't need the watch features, dedicated wearables (Oura, Whoop) score higher on sleep-specific metrics.
Best for you if…
Sleep tracking is near-zero marginal effort. Health app integration is unmatched — sleep flows into the broader iOS ecosystem.
FDA-cleared apnea detection (Sept 2024) is the only consumer device with this clearance. Real screening tool, not a gimmick.
Comfort and battery limits make Oura or Whoop the better dedicated pick. You'd carry a phone for everything else anyway.
iOS-only, full stop. Galaxy Watch 7 is the closest Android equivalent (not yet reviewed by SleepyHero).
Apple rates battery at up to 18 hours of normal use (up to 36 hours in Low Power Mode), so you need a daily charging routine. Oura's 5-8 days or Whoop's 5 days is a meaningfully different lifestyle.
Bottom line
Discontinued — if you are buying new, choose a current Apple Watch model. If you're already in iOS and want sleep tracking as part of a broader watch, this generation still does that job well and discounted stock can be good value. If sleep is your primary metric, dedicated wearables are better — but they require carrying a phone for everything else.

Frequently asked questions
Can you still buy the Apple Watch Series 10?
Not from Apple. Apple discontinued the Series 10 — its product page now redirects to Apple's watch collection index. Third-party sellers still list remaining stock, so it is findable, but there is no Apple-direct unit, no Apple warranty purchase path, and no free engraving. Buy a current model unless the discount on remaining Series 10 stock is steep enough to offset a shorter remaining software-support runway.
Is Apple Watch Series 10 worth buying for sleep tracking?
Only if you also want a smartwatch, and only at a discount now that it is discontinued. As a pure sleep tracker, Oura or Fitbit deliver better sleep data at lower cost with multi-day battery. Apple Watch wins when sleep is ONE feature among many (notifications, workouts, apps, calls) — and if that is you, a current Apple Watch model is the version to buy.
Does Apple Watch Series 10 detect sleep apnea?
Yes — sleep apnea notifications launched with watchOS 11 (Sep 2024). Supported on Series 9, 10, and Ultra 2. It monitors breathing disturbances during sleep and flags patterns consistent with moderate-to-severe sleep apnea.
Apple Watch vs Oura Ring — which sleeps better?
Oura for pure sleep quality tracking + comfort + battery. Apple Watch for iOS integration + smartwatch features + sleep apnea detection. If you already own an iPhone and don't mind nightly charging, Apple wins on data breadth; if not, Oura wins on comfort.
How long does the battery actually last for sleep tracking?
~18 hours real-world. If you charge 6am-7am while showering, you get through the day + sleep tracking. If you forget to charge, you'll wake up to a dead watch. Ultra 2 is the alternative if battery is a dealbreaker.
