This was in the family safe deposit box. From the mark inside the cover, I determined that it's a Waltham watch. It has a leather fob attached with a medallion (1.5" diam) from Saratoga Springs, NY. It also has the winding key. From other research, if I can assume the number on the cover is the serial number, it dates to around the mid-1800s. If I decided to sell it, I really don't know a fair price to ask. I can't find any exactly like it on eBay.
