Apple Watch Series 11 (46 mm, GPS)

The Apple Watch Series 11 is Apple’s main smartwatch for 2025; this entry covers the 46 mm aluminium GPS version. It offers an LTPO3 OLED Always-On display reaching 2,000 nits, Ion-X glass with a ceramic coating, the S10 chip and 24-hour battery life. Hypertension notifications and a sleep score join ECG, blood oxygen and wrist temperature measurements. In independent testing the heart rate was very close to a chest strap, but battery life was still found short; owners praise the health tracking, while some say the battery barely lasts a work shift.
