The pocket watch pictured below belonged to my grandfather and I’m trying to identify its make, type of movement, manufactured year, etc. The watch runs and keeps pretty good time although it mostly sits idle in a stored location. The only printing I can find is also pictured below and reads “ligne droite balancier chronometre spiral breguet”. The case is marked as K14. The watch serial number appears to be 114360. Any help you can provide is appreciated.
