I have recently had a Zenith watch handed down to me by my father. It was my great-grandfathers and I am trying to find out what it exactly is and what its production date may be. It has a number stamped into all 3 covers - 274198. On the mechanism it has the Swiss cross and the numbers 14447 below it. The face has the name Novoris on it. Do any of these numbers identify production? I know it is prior to 1904 because it has his initials and 1/1/1904 on the inside front cover. Any help or direction would be appreciated. Thank you in advance for your consideration.
