Mauron Musy

Founded in 2013 by Éric Mauron and Christophe Musy — not from a marketing plan, but from a refusal. A refusal to accept that a solution simply 'is what it is.' Coming from an industrial background, not a traditional watchmaking lineage, they came with questions and a mindset. This led to an invitation to Baselworld in 2015 and a first model in 2016. Their Manufacture is housed in a former farmhouse in the Broye Valley — far from the major watchmaking hubs — with around ten people producing approximately 300 timepieces per year. Everything is under one roof: design, engineering, production, and exchanges. All components are sourced from within a 60km radius. The defining innovation is the patented nO Ring® technology: a mechanical water-resistance solution that eliminates rubber gaskets entirely. Christophe Musy asked why a watch designed to last generations should depend on a perishable plastic component that needs replacing every three years. The answer was mechanical — he filed a patent and created the only water-resistant watch without gaskets. Water resistance relies purely on geometry, pressure, and extreme precision down to 0.01 micron, achieved through diamond paste finishing in-house. The four-part case architecture is directly derived from this patented approach.

Collections: MU03 Armure, MU04 GMT Sport, MU05 Architect, MU05 Blueprint, MU06 Unix, and MU09 Node° — the latest featuring a calibre that makes every connection visible. Five-year warranty.

The MU09 NODE°, unveiled through 2026, marks the manufacture's clearest step yet from technical curiosity to full haute horlogerie house: it introduces the brand's first entirely proprietary movement, the micro-rotor Calibre MM03, alongside its first-ever integrated bracelet, brushed, polished, and micro-blasted in the same grade 5 titanium as the 41mm case. The nO-Ring architecture itself has grown more ambitious in the process — the case now assembles from 24 separate components to achieve 200 metres of water resistance without a single rubber gasket, giving the watch a segmented, almost mechanical-exoskeleton look that reviewers have compared to a piece of architecture as much as a timepiece. Offered in anthracite, silver, or sunburst-blue dials with a choice of rose-gold or rhodium-plated hands, the collection is limited to 100 pieces for 2026 at CHF 48,000 each. The house has also shown a willingness to experiment outside pure engineering: the MU05 Architect skeleton was designed in collaboration with computational designer Arturo Tedeschi, applying algorithmic design principles to the visible movement architecture. From a converted farmhouse in the Broye Valley, with every component still sourced within 60 kilometres, Mauron Musy has spent little more than a decade turning one engineer's refusal to accept a rubber gasket's short lifespan into a proprietary movement, an integrated bracelet, and a design language unmistakably its own.
