My wife bought a jar of watches at the goodwill for $40. A few junk no name plastic watches but four watches worth adding to my collection. One is a vintage Bucherer. The case is small (33mm), it has his symbol and name at the top of the dial and "automatic incabloc" at the bottom. It runs/works but I am considering getting it cleaned and overhauled. I'm just wondering is it worth it? Does anyone know if the movement looks like a basic ETA or something unique to Bucherer? Thanks.
