Mexican Silver Watch Band

My wife has mentioned a few times recently that she wanted a watch. A real watch, that she has to wind. Not a smartwatch, not a Dick Tracy 2-way wrist-radio, but an honest-to-God WATCH.

Well, over the years, her tastes in jewelry has changed some. She still takes a minimalist approach to it, so I was more than a bit leery of trying to pick out a watch for her. There's a watch and clock shop here in Cullman that has done a little bit of work on one of my pocket watches, and they have a lot of interesting tall case clocks, mantle clocks, and antique watches. We went in, and while I was looking at something else (not interfering), she told the lady behind the counter what she was looking for.

Long story short, she picked this band, and what I think is a 1960's Elgin.

We both fell in love with the band, which is Mexican sterling with rose-gold accents. I've looked online, and can't find the maker's mark, but I suspect the band is also from the 1960's.

Anyone here familiar with Mexican markings? Any insights?

 

Very nice.
I have my grandfather's watch here and my grandmother's watch here and some of my mother's watches here that I gave her.
