it is 14k yg and dates back to 1954 i guess...the crown is unsigned, so is it not original to the watch? what about the second hand? how much is it worth? thank you for your responses?
It is difficult to tell from an angled photograph - a straight on, dial shot would be best. The Cal 120 is a really good movement, as are all Zeniths from this era, but there are plenty of them around. From what you can see, the dial is heavily spotted, so not that desirable for a relatively common watch. In stainless steel, it would probably sell for €200 to 300 so add a bit for the 14k gold.
