Apple Watch Series 11 42mm vs Apple Watch SE 3 (40mm) GPS + LTE

Buy the Series 11 42mm if health sensors and a bigger screen matter to you. It adds ECG, blood oxygen and skin temperature, which the SE 3 lacks, plus a 42mm display against the SE 3's 40mm. The SE 3 wins on connectivity: it has built-in LTE and 5G, so it works without your phone. Both run the same S10 chip, 64GB storage and 18-hour battery, and both are 50m swimproof. Owners praise the SE 3 as the value pick and the Series 11 for its fuller health suite.

  • Choose the Apple Watch Series 11 42mm if you want ECG, blood oxygen and skin temperature tracking and a larger screen.
  • Choose the Apple Watch SE 3 40mm if you want cellular built in so you can leave your iPhone behind.

What reviewers say

Apple Watch Series 11 42mm

Owners of recent Apple Watch models praise the bright always-on screen, accurate workout and heart rate tracking, and tight iPhone integration. Common complaints are the roughly one-day battery life and the iPhone-only requirement.

What people mention
  • BatteryCriticisedOwners say it needs a charge roughly every day, especially with workouts and always-on display.
  • DisplayPraisedThe always-on Retina screen is called bright and easy to read outdoors.
  • Fitness trackingPraisedGPS, heart rate and swim tracking are reported as accurate and simple to start.
  • CompatibilityMixedIt pairs seamlessly with iPhone but cannot be used with Android phones.

Apple Watch SE 3 (40mm) GPS + LTE

Reviewers treat the SE 3 as the sensible entry point to the Apple Watch, praising the always-on display and cellular option at the line's price. Most criticism centers on the missing ECG and blood oxygen sensors and the one-day battery.

What people mention
  • DisplayPraisedOwners like having an always-on screen on the SE for the first time, though some find it dim in bright sun.
  • BatteryCriticisedReviewers say the 18-hour rating holds but means charging every night.
  • Health sensorsMixedSleep apnea alerts and heart-rate warnings are welcomed, but the missing ECG and blood oxygen sensor are noted.
  • CellularPraisedBuyers value leaving the iPhone behind for calls, messages and music.

Questions and answers

Which is better for running and swimming?
Both are 50m swimproof and track the same core workouts. The Series 11 adds a larger screen and more sensors; the SE 3 adds cellular so you can run without your phone.
Does the SE 3 have ECG or blood oxygen?
No. The SE 3 has a heart sensor, temperature sensor and sleep apnea notifications, but ECG and blood oxygen are Series 11 features.
Which lasts longer?
Both are rated up to 18 hours. The SE 3 lists 32 hours in Low Power Mode; Apple gives the same figure for the Series 11.
Is the Series 11 worth stepping up to?
If you want ECG, blood oxygen and skin temperature, yes. If you mainly want calls and messages without your phone, the SE 3's cellular is the more useful upgrade.
Do both need an iPhone?
Yes. Both run watchOS and pair with an iPhone; the SE 3 listing requires iPhone 11 or later on iOS 26 or later.
