Watch SE, iPhone 7, iOS 15 - Apple Community
No, you are apparently unaware: the watch update is required upon setup as I wrote, unless Apple allows iOS 15 exception? The 1st generation SE (still being sold) is not latest OS out of box.

How would one go about updating a 1st gen… - Apple Community
You're going to find out it's almost impossible to update a series 1 watch. In theory, they should work with just about any iPhone, but an 8 + year old watch, with such outdated internals and extremely limited memory is going to be a difficult thing to update at best.

r/AppleWatch on Reddit: iOS 18 won't work at all with Apple Watch SE (1st Gen)
September 18, 2024 -

I just upgraded from the iPhone 13 Pro Max to the 16 Pro Max and found out that the 1st Gen Apple Watch will not even pair with any device running iOS 18. I can totally understand not being able to download to the new WatchOS due to compatibility, but not being able to be used at all is crazy.

Is this a known thing that iOS won't even function with iOS 18? Is my Apple Watch now useless?

Update: The issue that I was having was due to a corrupt iCloud backup. I lost all my data, but I was eventually able to update my watch. Apple continues to tell me that the SE 2nd Gen isn’t compatible with the iPhone 16, but that’s obviously not the case.
