Longines Skin Diver Nautilus Ref 7921. The first diving watch from Longines.
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 Longines long hunt...
Best,
Nicolas
