I have this Eska that is very unusual and I'm trying to find some info on it. I looked in all the wristwatch books that I have and can not seem to find and info.

Here is a side photo. The watch is 18kt.

It is very thin. It is marked Tiffany but not sure if it was made for Tiffany + Co.

Pritchard lists Eska as a brand of the Swiss manufacturer Sylvan Kocher & Cie, which she says was founded in Selzach in 1922 and was in business for at least the next 50 years.

Thank You
