Vaucher Manufacture Fleurier is expanding its range of ultra-thin movements and offer of development proposals for complications and modules

The Fleurier-based mechanical watch movement maker Vaucher is launching two new designs of its flagship ultra-thin, micro-rotor caliber, the Seed VMF 5401. Contemporary or classic, VMF presents two movements based on the same architecture. The company thus extends its range with this new, attractive offer. And through its Open R & D Department, it is now setting out on a mission to share its unique know-how and creativity in the realization of yet more original modules.

By putting its customization know-how into creating movement variants for smaller brands, VMF now offers a wider choice of visually appealing combinations to better match a watch’s intended design and style.

VMF’s numerous value propositions range from exclusive development of new movements, to the implementation of different levels of customization of the same movement architecture. This means its customers can rely on the comprehensive know-how, reliable products and high-end aesthetics that are the base elements of its reputation. Through the Open R & D Department, VMF opens up the creativity and skills of its technical office and watch laboratory for the development of original and tailor-made solutions. The originality of the Open R & D offer lies in its ability to offer innovative mechanisms to meet the specific needs of its customers

Ultra-thin micro-rotor calibers

The Seed VMF 5401 caliber is an ultra-thin, 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.

With Open R&D, Vaucher Manufacture Fleurier (VMF) positions itself as a creative center and full partner – without parallel in the Swiss watch industry – in mechanism, movement and watch development projects.

The aim of Open R&D is to establish itself as a one-stop-shop offering complete and tailor-made solutions, from the creation of original and innovative concepts (mechanisms, movements and / or watches) to their production – all in full conformity with the rigorous reliability, quality and production criteria that have made Vaucher Manufacture Fleurier’s Haute Horlogerie movements world-famous.
