That's an early Landeron/Hahn movement probably from the 1930's. There are many variations of this design so they're hard to pin down exactly. Yours has a broken Minute recording jumper which should be replaced if you can find one. Solid movement if you get a good one but parts are scarce.

Caliber of 15 lines, close to Landeron calibers but specific.
What does this could mean - was there specific caliber for Breitling signed monopusher chronographs from early 30s?

This is intresting as this same kind on movement can be found also on early
Löwenthal monopushers

https://www.ebay.com/itm/LOWENTHAL-Cron ... SwkrFaV8LC
and Eberhard monopushers as well
https://www.todocoleccion.net/relojes-a ... x173892092

So Hahn produced same kind Landeron specific movements additionally to Breitling for those as well or how this should to understand actually?

Can someone specify what Landeron movement this actually is - seems 15.5 ligne column-wheel movement with 5 column, sitting in 40mm case.


Sorry for my ignorance and I very highly appreciate your time and expertise.
