As I remember it, Christian Ferrier (son of Laurent) worked at Fabrique du Temps (high end movement maker) prior to coming on with LF. A couple of the movements were designed while he was at FDT, rough CNC'd there, then finished and assembled at LF, while a couple of the other movements were designed at LF (likely by Christian as well), CNC'd at FDT, then finished and assembled at LF. They are not an in-house, vertically aligned manufacturer, nor do they claim to be. They do have exquisite, and exquisitely finished movements,
