Each movement is assembled over eleven hours by a single watchmaker. The escapement wheel — 15 teeth, 0.08mm thick — oscillates 28,800 times per hour. Every tooth is finished under 6× magnification. A patience that cannot be automated.
"The master watchmaker works in silence, guided only by the tremor of a hairspring and the memory of a craft three centuries old."Maison Meridian — La Chaux-de-Fonds, 1891
