For most iPhone users this was the right Apple Watch. The Series 10 trims weight and thickness from the Series 9 and adds a depth gauge and water-temperature sensor. Sleep apnea notifications arrived alongside it in watchOS 11 but reached the Series 9 and Ultra 2 the same day — never a Series 10 exclusive. Superseded by the Series 11 in September 2025.
Strengths
- Lightest Apple Watch in years
- Sleep apnea detection (FDA-cleared)
- Same training metrics as Ultra 2 at half the price
Tradeoffs
- 18-hour battery is still last-gen by athletic-watch standards
- iPhone-only
- Discontinued — the Series 11 raises battery to 24 hours

Common questions
- How much does the Apple Watch Series 10 cost?
- The Apple Watch Series 10 starts at $399, with larger sizes and premium finishes costing more.

- No. Apple sells an optional premium tier at a monthly fee for deeper analysis, but the Apple Watch Series 10 tracks and syncs without it.
- How long does the Apple Watch Series 10 battery last?

- The Apple Watch Series 10 is rated 5 ATM (50m), which covers showering, swimming, and surface water sports. It is not a dive rating.
- Does the Apple Watch Series 10 work with iPhone and Android?
- It pairs with iPhone only — there is no Android app.
- Is the Apple Watch Series 10 still worth buying?
- The Apple Watch Series 10 came out in 2024 and Apple has discontinued it, so new stock is limited and prices vary. Check it against the current smartwatch lineup before buying.
