Seed VMF 5400 / H,M,D

Hour, minute, date window at 3h or 6h

Basic information

Vaucher Manufacture Fleurier proposes a small masterpiece of complexity barely 3.0 mm deep derived from its tradition and its artisanal-industrial manufacturing process. A development of the VMF 5300 movement, it retains the latter’s robustness and slenderness while adding a new automatic, allowing it to wind and recharge as quickly as a classic automatic. Specially optimised for the Seed VMF 5400 by the company atokalpa, the variable inertia balance ensures optimal isochronism. Designed to accommodate additional mechanisms

 > From 25 pieces in its Seed VMF 5400 version, with personalisation of the oscillating weight.

> From 250 pieces in its S-VMF 5400 version, with personalisation of the bridges (shapes and decorations) and of the oscillating weight.
