As far as I know there are pin-lever movements with 17 jewelsI'm sorry I can't ID it.
1)Are you sure its a pin pallet watch? It says Ancre on it. Edit - sorry, my mistake - lever it is.
2)Are you sure its Swiss? Swiss movements usually say 'Swiss' quite prominently.
I've got an idea, but it's impossible to verify except by looking at the movement up close from the right angle.I'm not sure. Perhaps one of the watchmakers can clarify.:think:
