Mmm I saw a stunning ref 7981 skin Diver in Nos condition on Parmegiani's website a few days ago. I really love the particularity of the red bezel but I still prefer ref 7150-1
A super rare beauty, from the late 50's. Finding one, moreover a correct one, is super challenging. This one has been auctioned by Phillips, some months ago. The elder sister of the Longines Diver we all know. Needless to say that it is one of my vintage ...
As you said a true challenging "mission" finding a nice exemplar. The one sold by Phillips is in great condition and the dial has a super cool patina. Best.
