Openworking is a challenging craft that requires hollowing out mechanical components without compromising performance. The Métiers d’Art Mécaniques Ajourées applies this technique to the hand-wound Calibre 4400, creating a three-dimensional architectural masterpiece. Artisans removed nearly half the material while adding Grand Feu enamel detailing to the movement's ring. This design balances airy aesthetics with complex functionality through meticulous hand engraving and enameling.
