I am new to the watch addiction and know very little about vintages. My dad gave me a few vintage watches (croton, timex, nicolet, and benrus) that were left in a box for years. The Longines seemed the most interesting as far as brands go. The dial is in the worst shape and it looks like its missing a jewel at the balance wheel. I need help in deciding if this watch is worth refinishing the dial and getting the movement serviced and running? I have no emotional attachment to this watch but I like the style of the dial but it is in bad shape!
