Rayville R58 movement?
Hi all,
I recently bought a vintage Corum extra-flat hand-wind watch. The seller claims that this watch uses a 'Rayville R58' movement. I know that Blancpain used the name Rayville in the 50's, so I assume it's really a BP movement. Does anybody know anything about the R58? Is this the same as the current extra-flat cal. 21? Pictures? I didn't find anything on the web or in my books, and I don't want to open the watch just for curiosity.
Thanks in advance!
