I have a Borel Fils & Cie mens gold pocket watch. It belonged to my grandfather, still works. On the inside of the case it has the numbers 56 and 14K inscribed inside a B. Also, the numbers 435503 are stamped inside the cover of the case, along with t he companies stylized logo.
Can anyone tell me the approximate value of the watch and is it worth having cleaned? If so, where? Thanks!
