Hi all,

I acquired a vintage piece from some time back and believed it is some sort of Landeron. Being new to chronograph movements I couldn't be sure.

Today, I managed to open up the case back and got some pictures of the movement: would love to hear any comments on what kind of movement it is and its condition.

 

Your second picture shows the maker’s trade mark and caliber number underneath the rim of the balance wheel. The trade mark is a letter or symbol in a shield, and the caliber number is below it. Your pictures aren’t clear enough to make the trade mark easily read. If you will identify the symbol in the shield and the number, we can help. Of course, there is a chance someone will recognize the make and model easily.

 

Ah I am away from my watchmaker so i don't have high res photos, thanks for the input

Start broad with shape of movement, orientation and options. Then start adding in more details if the list is to big.

 

My Bestfit catalog and Ranfft seem to indicate it is a Landeron 148. The shield under the balance wheel is likely an L.

 

Just found the 48 behind although I can't be sure what the 1st digit is

 

I would say L248 - as far as I remember, the L148 does not have shock protection. Both are later versions of the L48.
