Sicura Submarine Skin Divers Watch

A used 1960's vintage divers watch that was named the Submarine as it originally stood depths of 200m and earned the label 'super waterproof' - this was actually a very practical divers watch with large open face with Tritium lumen hands and hour markers for clear visibility under water and a rotating timer bezel to keep track of oxygen tank timing.
 
The 36mm case houses a Sicura 23 jewel hand-wind movement, and the watch sits on a newline green NATO style strap, and the watch winds well and works...
 
As a point of interest Sicura went on to acquire Breitling and the two companies merged, although this watch pre-dates that!
