zenith

Hello,

I am new to the forum and don’t have much knowledge about watches. I am currently the owner of a Zenith watch with a quartz movement, engraved with the name 'Stig Wallner'. The watch is made of 18K gold. I would like to identify it and, if possible, learn more about its history, whether it is rare or not, and its estimated value. Any information on this subject would be helpful."
