Vintage Yema Superman Diver Automatic Ref. 87062 Cal. 2452 (ETA)
The Yema Superman is a legendary French dive watch, first introduced in the 1970s.
And if you believe the interwebs the Superman was one of the first dive watches with a rotating bezel-locking mechanism, allowing for better underwater timing.
But we do know for a fact Doxa was more likely the originator of the unidirectional locking bezel.
Very SUPER!
Thank you for sharing this with us! I like the 1Z as 12 on the marker. Looks clever to me!
