Apple Watch SE 3 (GPS, 40mm)

The Apple Watch SE 3 (GPS, 40mm) is Apple's entry smartwatch: the S10 chip, an always-on display, sleep score and fast charging. For staff on iPhones who want notifications and the health basics without paying for a Series 11, it is the sensible pick. The one thing to know: it requires an iPhone.

What does the Watch SE 3 leave out?

• Apple's list price is $249 (Apple, Sep 2026) for 40mm GPS; the 44mm GPS model is $279.
• No ECG and no blood-oxygen sensing; those sit on the Series 11.
• Band sizes (S/M and M/L) and colours are separate listings, so check before ordering for a team.
• Apple's September 2026 event is expected to refresh the line, which may change prices.

Who should skip it

Anyone who wants the full health sensor set should buy the Series 11. Android users cannot pair it at all and should look at Samsung or Garmin.
