Incredibly cool and very rare Paul Portinoux "Sea Nymph" divers watch from the 50s with dark brown "cracked" leather dial appearance and large kite style applied luminous mass hour markers. 
 
Paul Portinoux used Swiss movements during this time, yet were not a large company. These examples are scarce and very unique.
 
The case measures 34mm and is full stainless steel screwback. 
 
There is something very charming about the look and feel of this watch. It is a conversation piece and you will be the only person wearing one.
