Good news! It appears that the connection stability issues during upgrade may have been due to a bug in the 0.7.1 software.
After upgrading my dev/unsealed watch to 1.2.0, I've been able to upload the same 1.2.0 image to the watch 4x in a row without any issues. I have basically no experience with the inner workings of the software so my diagnosis here is probably naive and simplistic _but_ it does seem that the OTA upload connection is much more stable after the 1.2.0 upgrade.
To anyone else experiencing this issue: I would suggest using nrfConnect to perform the initial 0.7.x -> 1.2.x update as it will automatically connect+retry the upload after you reset the watch. It will _eventually_ work but you might have to keep at it for awhile.
