Manufacture manual with twin barrels

Entirely designed, developed and assembled in the La Chaux-de-Fonds workshops, the MSE 311.00 calibre embodies Schwarz Etienne’s mechanical vision. A true sculpture in motion, it reflects the subtle balance between artisanal emotion and technical mastery.

With an impressive 120-hour power reserve, its performance stems from an optimised balance wheel and twin barrels mounted in parallel, ensuring a smooth and consistent flow of energy. Its refined finishes pay tribute to the finest watchmaking traditions, evoking the spirit of pocket watches through meticulous details that express a design language both rigorous and pure.
