My 4 is still working perfectly so I’m struggling to justify buying a 6 now, even battery is as good as when new. Maybe a 7 later this year.
I wouldn’t buy the SE because it doesn’t have the full medical benefits (no ECG, iirc). Does the SE do the auto fall detection?
Yep, it does pretty much everything except the always on face and the odd medical thing like ECG. I use my watch primarily for the notification and exercise functions so I'm not too fussed about those things.
