Hi All,
I bought on a market an old IWC with on the case the Ref. 648A, I added some pictures of it.
I can't find any information about this watch. I only found some 648AD information.
Please guy's let me know if you have any more information for me.
the movement look like a cal. 853, and the case is a 36.5mm
Thanks a lot for all your help...
