Hello everyone I need your help . I have a Longines Wittnauer AFUS Army type AII
I took apart the whole movement and I cannot find what caliber or what model this movement is I have searched everywhere throughout the Internet and cannot find any information what I would like is a balance staff for this movement I have pictures if anybody could help. I have read that some movements are 201/M caliper and some movements are 63 caliper but I still cannot find the staff and I don’t know what caliber I have. I measured the broken staff which was 5.7 mm without pivots so I’m assuming in 5.9 mm in length
thank you so much happy new year

Is the sticker still on the back of the clock?

Also be careful with the radium dial and hands, these aircraft clocks had a higher radium content than average clocks.

Are sure this measurement is correct, the Calibre 201 staff is a touch under 6.5mm overall length:???:

usual Staff replacement number for a Cal 201; Bestfit #878 or Ronda #1700

Thank you so much. I measured the staff which was broken but it looked like just the pivot tips were missing and that’s where I got that measurement but I will look into those models for the Staff rondo and best fit
I will let you know
Thanks again

So I have assemble the movement with a new staff, which works great! But now I have a problem when I screw down the top plate the stem winds and clicks. but no power is given to the train. I remove the barrel and fork and screw down plate tight all gears move freely. Re install the barrel and fork screw down the top plate slightly and the movement runs! When tightening the plate down movement stops. I think the arbor is to tight in the pivot holes for the arbor? How to you remove this type of barrel plate?? Or is there something else I should be looking for?
