Overview

• The three new watches — Series 11, Ultra 3, and SE 3 — share Apple’s S10 chip and watchOS 26, compressing performance differences across the lineup.
• SE 3 adds an Always-On display, on‑device Siri, and gesture controls at $249, though it omits ECG, blood‑oxygen measurements, and hypertension notifications.
• Series 11 earns praise for a real‑world jump to about 24 hours of use per charge and supports ECG, blood‑oxygen features, and FDA‑cleared hypertension notifications that will roll out soon.
• Ultra 3 introduces two‑way satellite tools including Emergency SOS and extends rated battery life to 42 hours for off‑grid use.
• All models offer 5G hardware on cellular versions, with regional limits such as disabled 5G in Canada at launch, and they reach stores on September 19 after preorders opened last week.
