10 BNCH ( A17 military )

Hi, i'm looking for a ratchet wheel for my  10 BNCH  type A17 ( MIL W3818 )  watch. I didn't find any in the market ( ebay etc..) Do you know if there is compatibility or interchangable pars for ratchet wheel with other bulova models?

Thanks

The 10BNCH is not from an ebauche and according to BesFit, is not interchnageable with other Bulova movts. Our own Bulova Interchange Catalague does not list it.

That said, this is a very basic part, and I would suggest trying a few from similar 10 1/2''' movts to see if any fit. If they do, let us know, because very little info exists as to this.
