AppleWatch to pair with new iPhone, problems bc Activation lock

I really need a workaround. Last Monday my iPhone 11 pro got damaged abd no way I can access it in any meaning of the consept. I bought a new iPhone 13, cloned it with an older iPhone I still use, but never thought my AppleWatch hadn’t and wouldn’t pair with the new phone untill this last weekend. According to Apple I must reset the Watch before I can pair it with the new phone. Really? My issue is very simple: I need to secure AppleWatch data somehow before re-setting it in order to pair it with my new iPhone. Those datas are important. If I can backup the Watch somehow and upload those to the Health and Training apps, it’d be cool.

Case solved! Old iPhone deleted in iCloud. Watch restored from the backup taken by iCloud as a step before deleting it.
