I agree with Mike, your watch is probably sorely in need of a regular service or "COA", that is, clean (disassemble, ultrasonically clean movement parts), oil (lubricate) and adjust its timekeeping accuracy once reassembled. This is usually required every 3 to 5 years for a mechanical watch. It's possible the watches former owner either neglected regular maintenance or got tired of spending the money to do so. Usually a watchmaker can see telltail signs of previous service simply by observing etched or inked date codes on the inside of the caseback, left by a previous watchmaker. I must admit I'm surprised the dealer you took it to didn't mention that the movement was "dry" (oils/lubricants evaporated) and in need of routine servicing. Most competent jewelers/watchmakers notice that need as soon as they open the back of the watch. Good luck! The watch is certainly worth the investment in a proper service!

: service it will be maybe a couple hundred more than that.
