Our verdict
For iPhone owners who want notifications, workout and sleep tracking and safety features without paying for a Series model, the SE 3 is the one to get. You give up the ECG and blood oxygen features of the pricier models, it needs charging most days, and it only works with an iPhone — for most people those are easy trade-offs.
Why you’ll like it
-
01
The Always-On Retina display, up to 1000 nits, shows the time and your stats without raising your wrist, even outdoors.

02
Double tap and wrist flick let you control the watch with one hand when the other is busy.
-
03
Sleep score, sleep stages and sleep apnea notifications help you understand and improve your nights.

Fast charging gives up to 8 hours of normal use in 15 minutes, so a quick top-up before work covers the day.
-
06
Swimproof to 50 m, with built-in GPS for runs, rides and pool sessions.

- iPhone owners buying their first smartwatch

No. It needs an iPhone 11 or later (including iPhone SE 2nd generation or later) running iOS 27 or later.
Does the SE 3 have ECG or blood oxygen?
Apple does not list them for the SE 3; they are on the pricier Series and Ultra models. The SE 3 does have heart-rate notifications, irregular rhythm notifications and a temperature sensor.
Can I swim with it?
Yes. It is water resistant to 50 m and rated swimproof, which suits pool and open-water swimming but not scuba diving.
