Series 0 uses watchOS 4.3.2, Series 1 & 2 uses 6.3.
There are at least two reports that installing iOS 15 beta causes crash/boot loops that are not recoverable.
I have been dealing with this for weeks first suspecting a bad battery. The watch will continue to cycle (sometimes holding for a while) even when disconnected. Re-pairing does not solve the issue. I had this with a "known good" refurb from Apple, who looked at my reports and also declared the original "good."
I have filed feedback as a bug report. But knowing Apple I am not sure they care. Looking at the behavior this is likely an incompatibility of data structures exchanged between the iPhone and the watch. Once the data is in the watch cache, it become broken.
Caveat emptor.
Please note your observations and file a bug report, if you see this, too.
