Finesse In The Service of Performance
At just 2.60 mm thick without date function (3.00 mm with date) and with a 65-hour power reserve, the SEED VMF 5500 family stands as one of the thinnest industrialised calibres on the market. Its variable-inertia balance wheel with gold inertia blocks and 3 Hz frequency ensure stable, reliable timekeeping. The movement is 100% lead-free.
Reliability That Makes The Difference
Certified for 10 years. Warranted for 8. At Vaucher Manufacture Fleurier, reliability is measured, not promised. The SEED VMF 5500 undergoes a rigorous testing protocol for its 10-year qualification and certification, and is subject to demanding quality controls throughout the entire manufacturing process. For brands, it is the assurance of building on a proven movement, designed to last.



Fully Customisable
Every calibre can become your own. Dial-side and bridge-side finishes are entirely customisable to the highest standards of Haute Horlogerie: Côtes de Genève, diamond-polished bevelling, circular graining, perlage, two-tone laser engraving. Ideal for skeletonisation, available in titanium, and compatible with additional complications (moon phase, perpetual calendar). Every detail can be reimagined so the movement tells your story.
