Suggestion on service for a Tudor Sub 7928

[pkrussel]

Good afternoon folks

I am trying to get my vintage 7928 serviced (cal 390) and a new old stock service dial installed (I already have) and maybe the hands painted to match the “new” dial.

It is running, just slow and I know it’ll need no gaskets, oil, regulation...hopefully no parts needed but who knows, as I know the 390s are a pain to work on and get parts for.

Any suggestions would be greatly appreciated.

Thank you TRF!
