If you are looking for a rare Longines, this is it!!! A mega rare 13ZN Hour Counter or 'Sommatore' in 18K gold. These are much rarer than the similar waterproof version in steel! This example has a very nice and exceedingly rare original silver dial with applied gold indexes and outer scale. It features gold hour/minute, blued sub & chrono hand and the red minute-counter hand. The oversize elegant 18K case with ref 5161 measures 39mm excl. original crown. Movement is Cal. 13ZN modified to 'count the hours' and is therefore not a flyback (working very well). It is accompanied by an original period Longines box and a Longines Certificate of Origin & Authenticity (the watch was checked at Longines) and was sold in 1946 to Prague. Attached is a very nice croco strap. Simply stunning!
