The SE is what you buy when you want an Apple Watch on your iPhone but don’t need the ECG app, blood oxygen, or the temperature sensor. Notifications, fitness tracking, fall detection, irregular-rhythm AFib notifications, and the App Store are all here. The compromise: no always-on display and a slimmer sensor stack. Superseded by the SE 3 in September 2025, which adds an always-on display and wrist temperature at the same price. watchOS 27 dropped it; watchOS 26 is its last major release.
Strengths
- Cheap entry into watchOS on the used market
- Same fall detection and crash detection as the flagship
- Aluminum-only case is light on the wrist
Tradeoffs
- No always-on display
- No ECG app, SpO₂, or temperature sensors
- Discontinued, and dropped by watchOS 27 — the SE 3 is the one to buy
