I purchased a vintage Tudor cushion from eBay seller said the watch was working great. I got it it kept stopping after communicating back and forth he said maybe in transit something got stuck. He suggested trying to reset again which I did. The watch worked overnight until the next day and it stopped completely can't even set it no second hand working at all. He advised me he wore it for a few months with no problems. This is my first vintage watch so do I sent it back or sent it out for repair . I only purchased it because he said it was working fine. I paid 500.00 not a lot of money but it didn't even work for a day. Thoughts?
