Apple Watch Series 11 - Aluminum Case

Smarter Health Insights, Now in a Slimmer Aluminum Design

Apple Watch Series 11 pairs a lightweight aluminum case with an Always-On Retina LTPO3 display that stays sharp and legible in any light, from 1 nit in the dark up to 2000 nits under the sun. The Ion-X front glass is twice as scratch-resistant as the outgoing aluminum model, and the S10 chip with a 4-core Neural Engine keeps everyday interactions fast, from checking notifications to launching workouts.

Health tracking takes a real step forward here, with hypertension notifications, a nightly Sleep Score, sleep apnea alerts, ECG, blood oxygen, and temperature sensing all built in. New wrist-flick and double-tap gestures make it easy to dismiss calls or scroll through the Smart Stack without touching the screen, while on-device Siri handles quick requests instantly.

Battery life covers a full day of use with a 24-hour rating, and a quick top-up gets you to roughly 80% in about 30 minutes. It stays connected through 5G and LTE on cellular models, Wi-Fi, Bluetooth 5.3, and second-generation Ultra Wideband, all wrapped in a WR50 swimproof, IP6X dust-resistant case.
