My iPhone died; would not charge or turn on.
I took it to Authorised Apple retailer (Not Apple Store)
instead of fixing it, they replaced it with a new phone
(_after a couple of weeks of waiting for them to get back to me ...
meanwhile I kept using my Apple Watch (Series 2 Model A1758 with OS 4.2.3) but was using a "temporary Android phone"
... the Watch has data I don't want to lose_)
So I now have a
new iPhone and want to pair my
existing Apple Watch
while preserving all the health/fitness tracking data that the Watch has been accumulating.
Note: I've done a bunch of searching to find out if this is possible, but not found anything so far ...
Also, I saw the similar question: How do I pair the Apple Watch with another iPhone?
but it assumes access to the original iPhone to which the Watch is paired, which is sadly, not the case; the original iPhone is gone.
