    On the side with dials thats something like M in the triangle.

    Could you say anything about this watch? About the movement? I guess its from early 1920.

    Best Regards,

    That is the mark of A. Michel SA of Grenchen, Switzerland. They joined Ebauches SA in 1926.

    From the styling, I would say 1930s. The movement is a low jewel count (probably four or six) cylinder escapement, and would be considered as more of a novelty movement than a serious timekeeper. The jump hour complication does give it some collectors interest.

    Thank you. I just found something about Michel SA. But I can not find this movement. The earliest caliber from ranfft is from late 1930 and looks really modern according to this one.

    You haven't giver the size, but some close models are: 83/4L 575 and 93/4L 350. This last one is very close only without the decorative cut out in the plate. A.Michel made lots of movements in the 20-30s and was very popular.

    It's definitely an A.Michel calibre 453

    ..which is a 10 1/2 lignes movement.
    Looks like it's in relatively good condition.
    According to what I've read, it's from the 1930s.

    Thank you! I have been just testing this watch for accuracy and it runs very well.
