My son's 1960's Premira (Valjoux 7733). I just fitted with a vintage BOR. What a combo! A very good friend of mine sold this to my son when he showed an interest and wanted a "Panda" style watch about a year ago. I split the cost with him, and another enthusiast was bitten by the bug!
I like this watch a lot. And I like how someone got the bracelet fixed (not me[emoji3]), by using really fine watchmaker tool- pair of pliers.
But it adds character to this watch for sure!
