From 1976 untill 1979 the company was building and selling watches that hold the famous 1200 Caliber; the slimmest movement ever that has been developped by Mr. Pierre Mathys, master watchmaker in La Chaux-de-Fonds.In the 70’s, Mr. Mathys designed and built the prototype of a revolutionary watch caliber, with the goal to make the slimmest watch movement in the world.
