Apple Watch Series 10

The Series 10 is thinner than its predecessors with a larger, brighter display that stays readable at a glance from an angle — a small change that matters dozens of times a day. Sleep apnoea detection and the full health sensor suite are present. Charging is faster, which makes overnight sleep tracking practical. Battery is still about eighteen hours, the weakest part of the package. Requires an iPhone. The most polished smartwatch for iOS users.
