    A jump hour movement

    Hi,

    I picked up this defective fake watch for its movement that I have never seen before. The movement looks like one of the Guangzhou or Naning Miyota variation, but the date mechanism is interesting. I also tried to replace the parts with another similar movement, but they are not interchangeable. The hour hand jumps 5 hours every hour. Was this type watch made by other brands before?

    Cheers,

    Zhang

    I only know 1 Chinese movement with the hour hand jumping in 5 hour increments every hour. Yet another member of the Seagull ST17 family, the Seagull ST1722 automatic movement. Pictures of the newest version of the ST1722 below - the movement in your watch looks slightly different.

    I own one of those jumphour watches but I never tried to see what type of movement was in there.
