This caliber SEED VHM 5401 is a high-end ebauche manufactured by Vaucher Manufacture Fleurier S.A., a high-end private label movement company based in Fleurier, Switzerland. Every movement made by Vaucher Fleurier is 100% Swiss made.

Ultra Thin

The SEED VMF 5401 is an ultra thin movement at only 2.6mm. To achieve this, it makes use of micro-rotor technology.

Private Labeling

Vaucher Fleurier specializes in private label movements made-to-order. In an brief interview with the manufacturer, they said:

“We offer all our calibers to third parties from 10 or 25 units depending on the caliber. From 150-250 units depending on the caliber it is possible to get deeper personalization such as the bridges.”

Basically that means they can handle full customization of the rotor with a minimum order of 10-25 pieces. Full customization and hand-finishing of the bridges for a minimum of 150-250 pieces per order. They can even go as far as adding additional complications for your project.

Watch companies using this movement can technically rename the caliber to their liking or own branding.


At the time of this post, there are six variations of the SEED VHM 5401 including:

  • SEED VMF 5401 H,M (hours/minutes)
  • SEED VMF 5401 H,M/S6H (hours/minutes/small seconds at 6:00)
  • SEED VMF 5401/180 (skeleton)
  • SEED VMF 5401/190 (skeleton with moon phase)
  • SEED VMF 5401/40 (hours/minutes/big date at 12)
  • SEED VMF 5401/50 (perpetual calendar)

Does SEED have a special meaning?

We contacted Vaucher Fleurier to find out what “SEED” meant before each caliber number:

Yes, the seed as the core and the first step which helps a new brand to blossom. 😉

Carl Suchy & Söhne Waltz N°1

The photo below is of a caliber SEED VHM 5401 found in a Carl Suchy & Söhne Waltz N°1 timepiece. This version is a highly customized VMH 5401/H,M,S6H. Carl Suchy is the only luxury watch brand from Vienna with brand name that has history since 1822.

The extra-thin movement allows the watch to measure at only 9.3mm thick.

“Visible through a sapphire crystal case back, Waltz N°1 is equipped with an adjusted self-winding mechanical VMF 5401 movement by VAUCHER FLEURIER. It offers fundamental gains in terms of precision, power reserve, and reliability. The extra-thin skeleton movement with gold-plated micro-rotor allows for the Waltz N°1’s slender form, light weight and great wearing comfort.” -Carl Suchy & Söhne

Carl Suchy has chosen not to rename the caliber to their own number, and in fact seem very proud to let the world know their movement was manufactured by Vaucher Fleurier.

This is beautiful! Would love to see a microbrand start using something like this. Tired of the same old Miyota and TMI watches on Kickstarter.

Can a mini rotor like that actually power a watch as well as a regular one?

yes, back in the 1960’s Universal Geneve created movements with micro rotors, their Polerouter watches.

There’s now a LOBINNI 1888 made in China that does a small rotor. It looks nicely done. See it via AliExpress.

Like many people, I understand little about how a watch works. I focus on the name and the dial and the design. Watch movements, however, confound me. I wouldn’t know a great watch movement if it hit me in the face. Of course, Philippe Dufour’s praise of A. Lange & Sohne is noted. I would, however, like a watchmakers opinion of the Vaucher Fleurier VMF 5401 micro-rotor movement. For me, it doesn’t matter if a… Read more »

Thank you for this post and your excellent work. I’m thinking about a watch with this movement but have one question..Can you feel the microrotor moving on this movement when you’re wearing it on the wrist?
