it comes in original plastic box

some useful information from web (from ranfft website),

but they have not been checked for correctness :
Dm= 26.6mm, Do= 27.0mm
F= 0.65mm
T= 1.9mm

Do outer diameter, thus the largest. Most movements have a flange a little bigger than Dm,

to rest on the case band or mounting frame.

Dm mounting diameter. With this diameter the movement fits into the aperture of the case or mounting frame
F mounting height, distance between dial plane* and mounting flange.

T stem height, distance between dial plane* and stem center

*) Movements with display discs on the dial side (e.g. calendar)  have occasionally no dial support.

In this case the surface of the discs is taken as reference plane for H, F, and T.

If a not permanently fixed dial spacer is supplied with the movement. its additional height is mentioned.

Hands
1.50 x 0.90 x 0.20mm

Due to the long storage time, small traces may have formed on the movement, but this has no effect on the function.

Because the movement almost 50 years old is, it have to be serviced before installation

a fine adjustment might be necessary.
