I am very new to this so please bear with me. I recently aquired an old pocket watch that used to be my grandfather's. I first found it several years ago while cleaning up an old shed at his house. I was about eight years old at the time and remember the gears being rusty in places. My uncle took the watch and had it repaired to work again. The only thing I know was replaced was the spring. I know le locle is Swiss but have no idea as far as the date is concerned. Any information about the watch would be greatly appreciated. I realize many of the original identification factors may have been lost, but here I go.
Watch is hunter case, key wound and key set.
No markings on the face, but it is original.
On the front of the case there is a non filled-in crest of some sort.
Under the back case it reads, "patent lever,
full" then maybe "Travelled,
On the inside of the back case, the number "54929" is stamped. Under that is a sort of house-shaped mark over "C6"
The only markings on the movement are the letters "SIF"
Additional note: the watch runs but will only keep running if it is face down. Any other orientation and it quickly stops. Also, it requires a gentle rotating motion to get it going. Any ideas on what could be causing these problems?
Thanks for your help in advance.
