Q: What is the approximate value of this watch?

Muito obrigado. Vou postar o post no idioma nativo do site, e peço desculpas por esse desvio.

The case is very worn.
Movt. needs a clean. Does it work?

It does, but it needs a little maintenance.

It works very well. But it is necessary to perform a small maintenance.

Best valuation will be from finished auctions on ebay.
