Watch Series 10

The Series 10 brought a thinner case and bigger screen; buy it used now that Apple sells the Series 12.

Buying call

Buy the Apple Watch Series 10 used if you want a thin, light iPhone watch with a big, wide-angle screen for far less than a new Series 12. Reviewers liked its slimmer case, ticking-second always-on display, depth and water-temperature sensors and excellent call voice isolation. Skip it if battery matters, since it didn't improve on the Series 9's 18-hour rating. It's iPhone only.
