Basic information

Extra-thin micro-rotor calibers

The Seed VMF 5401 caliber is an extrathin, 2.6mm micro-rotor. This caliber with its potential for extreme personalization figures in, for example, prestigious collections by Hermès, Parmigiani and Richard Mille.

The Seed VMF 5401/32 variant offers lines and finishes from the pure tradition of Haute Horlogerie. It is intended for classic high-end models. The Seed VMF 5401/33 variant takes on a contemporary look through new decoration technologies, with laser relief engraving combined with geometric skeletonization. Its modernity is also expressed by the anthracite color produced by galvanic treatment.
