I am trying to identify the movement that these winding stem are used for. They have a "D" shaped winding section (where a square section is usually).
Here are some pertinent dimensions the tap size is 1.20 mm (Measures 1.15 mm).
The "D" measures 1.10 mm, and the section around it is 1.30 mm.
The major diameter of the stem is 1.90 mm
The "pilot" is 0.60 mm
The length from the end of the "D" to the beginning of the groove is 1.5 mm
Any help woud be appreciated..
And allow me to thank anyone who looks and tries to help.
