Finally I could solve the "Problem"
A K 56 Kalaschnikoff, has nothing to to with an AK 47.
It is A K al. 56 Savonette * pocket watch delivered with a
named dial and "cuvette" to*Kalaschnikoff & Fils".
As many pocket watch collectors know, the caliber numbering was initially Lep.
c.55 and Sav. c.58 for the Caliber called "Schaffhausen" and Lep. c.57 and
Sav. c.56 for the Movement with the divided Plate (Escape Wheel,Seconds Wheel,
Intermediat Wheel under one part, minutes wheel and Barrel under the other
part)
Later, when the c.55/58 Caliber was not more produced, the pair c.57/c.56
became the numbering c.57/c.58 (the lowernumber for the Lepine/Open Face and
1 higher for the Savonette /Hunter
Here 2 pictures of the "Kalaschnikoff"
