Calibre VMF 5401 is an ultra-thin micro-rotor automatic watch movement produced by Vaucher Manufacture Fleurier.


Derived from Cal. VMF 5301, Cal. VMF 5401 measures 13¼ ligne (30.0 mm) in diameter and is just 2.6 mm thick. It has a power reserve of approximately 42 hours. The micro-rotor automatic winding system is uni-directional. The variable inertia balance uses a flat balance spring attached to a mobile stud carrier.

Calibre VMF 5401 is used by a number of watch brands, including parent Parmigiani Fleurier, Hermès, and Richard Mille.
