Apple Watch Series 11

For most iPhone users this is the one. The Series 11 keeps the Series 10’s sizes and sensors but pushes battery from 18 hours to 24 — the first real move on that number in years — and hardens the aluminium with a ceramic coating. It is also the first Apple Watch with hypertension notifications, which watch the optical sensor over rolling 30-day windows and flag persistent signs of high blood pressure. Read that carefully: it is a screening prompt, not a measurement, and the watch still cannot tell you a number. Sleep score, sleep apnea alerts, Training Load, and Cardio Fitness are all free in watchOS. Titanium replaces steel at the top of the range.
