I do use analog watches, but nothing vintage.
I've got an electro-mechanical clock, a Junghans ATO, that my dad bought in Germany while stationed there in the 50's. Very cool, but maybe not of interest?
Instead, let me offer a vintage bike item that I used as a clock back when they first came out. This one is currently mounted on my '74 Raleigh International.
Honestly.. that was such a revelation at the time!!
Sooo much better than those little cyclometers that used the little striker mounted in the spokes, and even a bit better than the Huret Multito.
