    Waltham Movement question.

    Anybody have any ideas about this movement? I assume it is a Swiss one but I am a lot more familiar with American and Japanese automatics. No wonder I could not hear it wind with that tiny rotor. It looks to be mid 60s to 70s to me.

    I initially thought that the finish was too crude for a Swiss movement and would have gone for some sort of Japanese movement. In the end, I actually came up with something German:

    The outer rotor segment is gone so it probably doesn't wind very efficiently.

    No import code on the balance, so probably after 1968.

    Hmmm I found the rotor to be small but that is what it looked like when I opened it and the watch runs fine and holds a wind for around 20 hours.

    I may well still wind - but I am sure it would wind rather better if the outer rotor segment was still there! In addition, you can always wind it manually (although it does tend to wear out the automatic winding system somewhat).....
