    Info on vintage Tavannes pocket watch

    Hi all,

    I just completed restoration of an old Tavannes pocket watch my buddy picked up at an antiques dealer.

    As a watchmaking student it was a good challenge, the work done included, turning a new balance staff, straightening a bent wheel pivot, cleaning the dial, polishing/re-flaming the hands (to a burgundy red), replacing the crystal, polishing the case).

    Now that the work is completed, I was wondering if anyone could shed some light on the origins/history of this watch.

    The movement is marked Tavannes Watch Co, 15 jewels, 4 adjts, swiss, Ref 919.

    The case is stamped 35492 but I'm not certain if it's the original case.

    Best,

    Beautiful work...

    Did you have to anneal the wheel pivot before straightening? What was the process you used?

    Thank you!

    No annealing was needed for the steel. Luckily the bent pivot was also the extended small seconds hand axis, it was bent so slightly it was barely visible, but enough to cause enough friction, once the petite seconde was installed, to stop the watch.

    I placed the wheel on a lathe and very gently tapped the pivot straight with a small file while rotating the wheel to examine it. I know it's usually a technique reserved for clock pivot straightening but it worked well.

    Great Job
    Where are you studying watchmaking?

    A simple google search of CYMA Tavannes will reveal all.

    Fantastic
    That must be nearly the last school world wide
    The NAWCC School of Horology in USA closed in 2012.
    None in Europe

    Cool. I have had some success straightening sub-seconds posts - but always seem to break the others (escape wheels are the worst). I hope to see some more of your work...
