Some time ago I bought a gold Zenith manual wind watch for my wife as part of the celebration for a very special occasion which has been ruined by the pandemic. The watch was to go in April for a service and the case and bracelet to the goldsmith for repair of a hairline crack to the clasp . Fortunately I still have the watch and will still be able to give it to her.
I have been trying to find out the age and model of the watch online but cannot find much information about ladies' Zenith watches in general or this one in particular so any information would be appreciated. There is a Z above a W, a C followd by a superscript o as in the abbreviation for company all within a triangle. I cannot find this maker in my list of UK goldsmiths unfortunately. The diameter is ~22mm. and the watch case back has sloped sides but I have not opened it.
I found a photo of another gold Zenith with a similar case number but starting with 64, could this be the date of the watch?
I know that there is a ladies' watch forum but thought that I might get more help here, thanks.
