Apple Watch SE 3 Review: The iPhone Owner's Default Pick
Our verdict
The Apple Watch SE 3 is the sensible Apple Watch for most iPhone owners, adding an always-on display and fast charging to a smooth, well-supported watch, though it skips ECG and blood-oxygen readings.
Buy it if
- iPhone owners buying their first Apple Watch
- Parents and older family members who benefit from fall detection and Emergency SOS
- People who want sleep tracking and can charge briefly each day
Skip it if
- You use an Android phone
- You want ECG or blood-oxygen readings
- You want a week of battery
What we like
- Always-on display for the first time on an SE, rated up to 1,000 nits
- Macworld reached 80% charge in 48 minutes; Apple says 15 minutes gives 8 hours
- S10 chip keeps watchOS smooth and should get years of updates
- Macworld often reached bedtime with 50–70% battery left
- Sleep score, wrist temperature and cycle tracking included
What we don’t
- No ECG app and no blood-oxygen measurement
- Apple rates battery at 18 hours, versus 24 on the Series models
- Works only with an iPhone
- Smaller screen than current Series models

The Apple Watch SE 3 is for iPhone owners who want a reliable, well-supported smartwatch for notifications, workouts, sleep and safety features without paying Series 12 prices. The trade-off is health depth and endurance: there is no ECG or blood-oxygen reading, and you will charge it every day or two rather than once a week.
Does it work with Android?
No. An Apple Watch needs an iPhone, and that is the first filter for most Indian buyers. If you use Android, skip to the Amazfit Active 2 or a Wear OS watch.
How long does the battery last?
Apple still rates it at 18 hours, or 32 hours in Low Power Mode, the same as earlier SE models. Macworld found the battery is about 12% larger than the SE 2’s and usually reached bedtime with 50–70% left, often lasting into a second afternoon; once it ran two days and two nights. That is enough to wear it overnight for sleep tracking if you top up during your morning routine.
How fast does it charge?
Apple claims about 80% in 45 minutes and 8 hours of use from 15 minutes. Macworld measured 48 minutes from zero to 80%, close to the claim. Fast charging matters more now that sleep tracking means the watch is on your wrist at night.
What health features are missing?
Macworld confirms there is still no ECG app and no blood-oxygen measurement. You do get the optical heart sensor with heart-health notifications, wrist-temperature sensing, sleep score and cycle tracking. As with any wearable, treat the readings as wellness information, not a diagnosis.
Is the always-on display worth it?
It is the biggest upgrade. Apple rates it at up to 1,000 nits, and Macworld saw no scratches on the Ion-X glass after two weeks. The screen is the same size as the SE 2’s, smaller than the current Series watches.
Is it a good watch for elderly parents?
The SE line supports fall detection and Emergency SOS, which alert contacts after a hard fall. The parent needs an iPhone, and a cellular model is better if they often go out without the phone.
What about service in India?
The warranty is one year. Apple’s own stores are in only a few metros, so most owners use authorised service providers; screen and battery repairs out of warranty are expensive, so AppleCare+ is worth pricing.
What we could not verify
We found no independent heart-rate accuracy test against a chest strap specific to the SE 3.
How we researched
We have not used the Apple Watch SE 3. This review draws on Apple's launch specifications and Indian prices as reported by FoneArena, Macworld's two-week review including charging timings, and reviews from Tom's Guide, TechRadar and Expert Reviews.
We have not tested this product ourselves. This review is based on published specifications, the manual, other publications’ tests and owner feedback.
