Vaucher Manufacture Fleurier Introduces the Upgraded VMF 5500 Micro‑Rotor Movement
Vaucher Manufacture Fleurier introduced the VM 5500, an upgraded ultra‑thin micro‑rotor calibre that retains the 30 mm diameter and 2.6 mm height of its predecessor, the VM 5400, ensuring full interchangeability for existing watches. The redesign optimises the kinetic chain, boosting power reserve from 45 to 65 hours, redesigning the gear train and improving materials, while maintaining the 3 Hz regulating organ with a metallic hairspring and gold inertia blocks. Durability targets include a 10‑year homologation and an 8‑year service guarantee, reflecting the company’s long‑term commitment to reliability and serviceability. The VM 5500’s modern production capabilities allow greater aesthetic and technical customisation, eliminating previously used stamped components and expanding options for brands. Vaucher’s portfolio, supported by the Sandoz Family Foundation and partners such as Hermès, continues to focus on high‑end mechanical movements, supplying prestigious brands like TAG Heuer, Richard Mille, and Audemars Piguet with precision‑engineered calibres.
