Even if a watch watch is housed in a case of gold or silver accompanied by an ornate, finely tuned movement, the value is often determined by condition. The easiest way to tell whether or not a watch is functional, is to wind it and wait. If a watch keeps time and both hands tick by slowly and smoothly, the watch is most likely in good working order. Even if the hands of a watch do not move, listen for some ticking or humming. A clear tick and a bright ringing noise are good indicators that the watch is in fairly good working order. To fix any mechanical issues, consider visiting a professional watch repair shop.
