Here is mine. IVe had an Apple Watch Nike + originally from January to June then sold it.
I purchased another - sellers remorse last month. I noticed (3rd attachment) when you restore iOS from a backup and use a new Watch (restoring from the iOS Watch backup) Health app sees it as a new device. I'll bet this has to do with iOS Privacy and Security guidelines for device identification getting new certs.
Still when I deleted the previous Watch listing the data stated for a few hours then deleted previous workout and health data. I wish it kept the data since I restored it without confusing it as two devices. All achievements previously attained is gone
