I own this fantastic vintage Vacheron Constantin Ref. 6268 in red gold. Currently, it is fitted with a modern red gold V-C buckle. It looks fine, but I notice a tiny difference in the colour between the two (the buckle being very slightly more reddish), and also I believe a contemporary buckle will look even better:
I am aware that the vintage V-C buckles often looked rather generic. Any help, at best with pics, would be much appreciated!
would post on the Lounge the story you had written on its acquisition.
Regarding the vintage buckles, here's a scan Doc posted some time ago of what they looked like:
Buckles like the one below were used in the late 60s-70s
Considering how difficult these buckles are to come by I systematically put a modern half Maltese cross buckle on my vintage watches.
