I just picked up the little baby on the left. It's a Calibre 64 "pendant" watch --the sort of thing ladies wore on chains. In a sense buying this watch was a mistake --I thought the movement was among the first 64's IWC produced. It's a little later, but there was instead a very nice surprise. The case has a display back, which is quite rare.
The middle one is a cal. 77 --a "normal" sized pocket watch. To the right is a really large one --a "de-Nazified" German Navy c. 67 that's a whopping 57mm wide.
On the small one --my wife finally has found an IWC watch she'll wear. I still need to work on her relative to a 3714 with diamonds.
Regards,
Michael
