Where can I find more about Lucien Piccard?

[DelK]

Found this at a charity auction. Almost no information about these found so far. Does anyone recognize it?

Lucien Piccard were a brand, who like many brands used movements from a movement maker. This one is funny, as it's marked Lanco on the rotor (who did make movements in addition to selling complete watches), but the movement is an ETA 2772.

I also found Aetos Watch Co. noted on the back, but can't find much about them, either. Thanks for your info on the movement!
