    I think I've seen tear-downs, but it would be interesting to know more about the history of this movement.

    What's the history of the 2416b Vostok movement? ...

    Does anyone know who designed this movement and roughly when? Was it a Soviet copy of a Swiss design? Or a from-scratch work?

    Any notable similarities to or differences from ETA's offerings such as the 2824?

    I would love to see a review and tear-down of one someday. Morbid curiosity I guess.

    Thanks!
    Chris

    2416B is an automatic version of a 24xx movement. developed first by Raketa (the handwound version - most likely) produced in enormous quantaties by Vostok since the '70. The automatic version was introduced in the eighties AFAIK. The base movement is a Soviet designed movement (not a straight copy) - a simple construction with indirectly driven second hand. the automatic winder is a Vostok construction, with a ball bearing rotor, two roller freewheels (elgin or Gyromatic style reversers) and a directional clutch that separates the winder from the ratchet wheel during hand-winding. Apart from the weird construction where a small piece of brass keeps the roller freewheels in their place (normally they should be between two plate IMO) it is a very good, well designed automatic movement. Most problems people have with it (ant there are plenty) come not from bad design, but from Vostok's dreadful lubrication. It is not a copy of anything, at least not a straight copy. Some technical similarities to other movements are obvious, but it's entirely a Soviet construction.
