The Apple Watch SE 3 is Apple's lower-cost smartwatch, now with an always-on display, a faster chip and cellular built in. It covers the essentials well: heart-rate and irregular-rhythm alerts, sleep tracking with a sleep score and sleep apnea notifications, the Vitals app, workout tracking and fall and crash detection. It lacks the ECG, blood-oxygen and temperature-sensing depth of the Series 11 and the rugged build of the Ultra, but it does the core health and safety jobs for far less. It suits first-time smartwatch buyers, iPhone owners who want cellular calls without their phone, and anyone focused on fitness and safety basics.

Owners and reviewers treat the SE 3 as the sensible Apple Watch: it handles notifications, workouts, sleep and safety alerts reliably and the always-on display and cellular are welcome additions. Most criticism centers on battery life and the health sensors it leaves out compared with pricier models.
Apple Watch SE 3 is a GPS + Cellular smartwatch with a 40mm Midnight aluminum case and a Midnight Sport Band. It has an always-on display, so the time and watch face stay visible without raising your wrist. Faces are customizable, and the watch works with a range of bands in different colors, styles, and materials.
For health tracking, it sends alerts for an irregular heart rhythm and for an unusually high or low heart rate. It offers overnight metrics in the Vitals app, a sleep score, and sleep apnea notifications. Sensors track wrist temperature during sleep, and you can log periods and symptoms, get period predictions, and get notified of cycle deviations.
It tracks workouts from running and strength training to daily step goals, with real-time metrics. Workout Buddy, powered by Apple Intelligence, works from a nearby iPhone. The watch can detect a hard fall or severe car crash and help connect you to emergency services and your emergency contacts. Check In can notify a loved one when you arrive at your destination.
