Need help identifying a movement

[marcusg83]

Hello everyone. I'm working on a Lucien piccard watch and would like to know if anybody could identify the base model for this movement. Seeing as Lucien piccard scratched off the actual Maker's Mark. All I have to go by is LP78 and the letters LA underneath the balance wheel. 

 

Any help would be greatly appreciated. 

Thanks, Marcus

Looks like it’s based on and shares many parts with a Peseux 7020, but is 11.5 lignes instead of 10.5

I have to say that it was giving me a bit of a Peseux vibe. I have a few GP Seahawks, and a Barthelay for my GF, that I seem to recall having that bevel at the balance-cock foot. Good find on the LP78. It did seem like that was the caliber number, but I didn't see it on Ranfft (Perhaps I'm "overdepending"?), so I gave up. I did notice that the number inside the shield with the "LP" seemed to indicate the model/caliber number. Good work, on finding that parts list., StuartBaker104!
