Anonymous 1930s/40s chronograph - help to identify

[Knebo]

Hello all, 

I found this interesting 37mm chronograph and appreciate help in identifying it - especially the movement. 

Since the case is 37mm and the movement mostly fills it, the movement must also be rather large. Maybe between 31-33mm.

That's all I have. 

Cheers, 

CK

So after going through dozens of random pictures resulting from a Google search for "vintage chronograph movement", I may have a match. 

The Landeron 52 is 14.5 ligne= 32.6mm. Which also seems to match the proportions of the pictures I have.

What do you think? Did I get it right? 

Do you know anything about this movement?
