I have an original Apple Watch. I have upgraded from time to time and now have the Ultra 2. But I always kept the Apple Watch 0 and from time to time would put it on charge. It is not paired to my iPhone and usually, because on some occasions I had let it go flat, it had not retained its memory of date and time. It was usually far out and for years I have never bothered about that, just concerned to ensure I keep the battery healthy. A few days ago I put it on charge and after a short time noticed it was showing the correct time date etc. Not happened before. It also now shows correct entries in the calendar and even in the music app the Playlists are right. I assume it connects to my iCloud account even though not paired to my iPhone or any iPhone but does anybody know if Apple have done something recently that just might have triggered this?
