Watch is in very good condition except for the strong patina on the dial that also damaged the sign. It’s been flacking. Now it’s cleaned and with Zenith Caliber 40 manual wind movement it’s a desirable watch. This specific movement, identified by its features and common use in the Zenith Sporto line, was produced from the late 1940s to the mid-1950s and has 17 jewels. It is a robust movement designed for everyday wear.
