I'm looking into restoring one of my father's old watches. It's a Wyler Dynawind(Automatic). From the info gathered, he purchased the watch anywhere from late 60's-71. I don't know much about the watch, such as caliber, production quality, vice versa. The case seems to be dark rose gold tone. I cann't tell the difference from tone to solid Gold. Can anybody help me with more info on this watch and also refer me to somebody who could help me with the restoration?
Here is a quick vid of the watch for visual confirmation.
