Apple Watch sync

Hello,

I recently bought a new iPhone as my old one got broken. I can no longer use/access the old phone unfortunately, it is not repairable.

I need to pair my watch with my new phone but it looks like, from my online research, to be able to do that I need to erase the watch first -> it’s not possible to sync one watch with multiple phones.

I don’t want to lose any data on my watch, so I would like to know how if there’s a way to sync the watch with the new iphone without erasing it.

Any help/guidance will be appreciated.

Thanks a lot,

Gorkem
