Apple Watch Series 10 (42 mm, GPS) review 2026

The best smartwatch there is — thinner, with a bigger wide-angle OLED, sleep apnoea detection and the fastest heart-rate response we measured — if you have an iPhone

Is the Apple Watch Series 10 Worth It?

Best smartwatch overall. The Series 10 is the most complete wrist computer and, in our tests, the most accurate at the things that matter to health. Its battery is the one thing every Garmin does better, and that is the whole argument against it.
