Bought my wife this IWC Mark 12 in the early 90's (brand new). But she did not really use it as she likes the other watches in her collection. It seems that we do not need this watch anymore.
I think I still have (1) the original invoice for the watch, (2) IWC cards and (3) possibly some IWC records from Switzerland for lubrication and calibration services, as well as new straps, etc.
Of course, the watch is working :)
No box. I throw it away few years ago when I was cleaning up our place.
