I've recently been browsing the affordable watch forum and have always wondered about vintage watches. How do you know the watch you're buying is going to work? I have heard to factor in about 100 dollars for a service, so I guess it doesnt really matter if it doesnt work right? Also there is a lot of mention on the other forum of seiko, orient etc, are there similar affordable and reliable vintage brands? I have read bulova is a good starter brand. Last question, how long will a vintage watch last? Forever?
