This nicely working watch is a a very early Zenith manual wind mechanical watch from around the 1955-1960. The Calibre 106 is a very nice movement and the variation 106-50-6 was the first ones having a incabloc shock protection. The watch case is in very good condition as well as the watch movement. The dial shows some unique patine, which seems to me like is based on oxidation because of very old fingerprints? Looks very stylish - together with the lice brown strap the vintage look is perfect. As far as i know, this crown is original. In the 50-60s Zenith had some watches without a their logo on the crown. Even the logo and the name on the dial was not embossed like in later versions. Please see the highres-photos for details regarding the condition of the watch, the strap and the movement.
