I recently purchased a nice collection of pocket watches. I have been able to identify most of them, but this one is giving me trouble. On the face cover (in a banner) it reads: Warranted Fine Gold and then towards the bottom it has the number 63. On the first back cover it has the numbers 16285 and then (in a banner) Warranted Fine Gold. Lightly inscribed it reads 11-17-68 and then 1-3 Made. Towards the bottom it has 463 with an 8 under it. On the second back cover it has the a script N that swoops over into an oval. In the oval it reads: 463. Under this it has in script: T. Courvoisier, then Locle in an emblem. The only thing that I can find on the movement is fast and slow. It comes in an old burlwood felt lined case with the words on the inside top: L. Reymond Locle. Thank you for any information you can give me.
