When i walked up to the table that this was sitting on i got really exited, and i got more exited when i saw the price. I only got this for $30.. The silver hallmarks are dated 1798 and the maker is James Wintle, but Ive been told the watch movement is older.
In my experience, the movement is the real prize. If you can verify the movement is complete and working, this will greatly enhance the value. The only issue is any watchmaker or jeweler will charge you an arm and a leg to look over it and tinker with it. Great find!
