Overview

• Reviews highlight practical upgrades on SE 3 including an always‑on display, wrist temperature sensing, gesture controls, on‑device Siri, faster charging, and tougher Ion‑X glass.
• SE 3 runs the same S10 processor as Series 11, narrowing day‑to‑day performance differences to screen size, a few hours of battery life, and missing health apps.
• In real‑world tests, Ultra 3’s GPS proved only marginally more accurate than SE 3 by roughly 15 metres over a 3km walk, reinforcing the SE’s suitability for most workouts.
• All new models include 5G hardware, but Canadian carriers do not support 5G watch plans and the feature remains disabled locally, even though devices match U.S. hardware.
• Hypertension notifications are rolling out with FDA clearance on Series 11 and Ultra 3, but are not available in Canada, and SE 3 still lacks ECG and Blood Oxygen apps along with the software keyboard.
