Chronograph Movement Identification

[MattWatch]

Hi All,

Could anyone help me identify this single pusher chrono movement please?

Thanks in advance

Very old Landeron, cal. 3 or similar

HI, it looks like a Landron 39 to me but I can't identify it, unfortunately you might have to un-case and pull the hands and dial off, the dial screws are on the same side as the picture showing, when this is done we can hopefully finger print the setting bridge for ID, wait for another member to come forward with more knowledge as it is early in the post, I look forward to seeing the maker....

Looks like the landerton 39 according to the bestfit book although no mention of the pusher / s

Thanks chaps. To be honest I'm probably not going to pull it apart to get the dial side of the movement, so I'll base further research on the Landeron 39 as a starting point.

Giving the diameter would help. I suppose it is 15 lin.
