Mauron Musy MU09 Node
Relatively young in the watchmaking world, Mauron Musy has a few unique tricks up its proverbial sleeve when it comes to mechanical watches. Its newest timepiece, the MU09 Node°, is a perfect example. The new 41mm titanium model introduces the independent Swiss brand’s first manufacture movement and first integrated bracelet, while continuing the technical hallmark that put Mauron Musy on collectors’ radar: its patented nO-Ring® gasket-free sealing system.
The MU09 Node° is significant because it represents a broader maturation of the brand. Since its founding in 2013, Mauron Musy has built a reputation around engineering-first watchmaking rather than traditional decorative codes. With Node°, that philosophy extends beyond the case into an all-new proprietary caliber and a more streamlined, contemporary sports-watch profile.
The Mauron Musy MU09 Node features the brand’s first integrated titanium bracelet and a new movement.
At the heart of the watch is the new Caliber MM03, a micro-rotor automatic movement developed over more than a decade. Measuring just 5.5mm thick, the caliber delivers an impressive four-day power reserve and boasts a tungsten micro-rotor mounted on ball bearings. It beats at 28,800 vibrations per hour and features a free-sprung balance with inertia screws for enhanced chronometric stability. The movement is visible through the semi-openworked dial, where a bold angular balance bridge at 9 o’clock creates an architectural focal point. Mauron Musy also notes that each surface suitable for hand-finishing receives traditional artisanal treatment.
The watch is powered by the MM03 automatic movement with micro rotor.
Still, the technical centerpiece remains the brand’s patented nO-Ring® system. In conventional watches, water resistance is achieved with elastomer gaskets that can age, compress, or deteriorate over time. Christophe Musy, who came from an industrial mechanics background, set out to solve that weakness by creating a fully mechanical sealing system requiring no rubber gaskets at all. The result became Mauron Musy’s defining innovation and the structural basis for its signature bolted case construction. In the MU09 Node°, that concept continues in a refined Grade 5 titanium case measuring 41mm in diameter and 12.8mm thick, with water resistance rated to 20 ATM.
The Mauron Musy MU09 Node in titanium comes in three color ways.
For the first time, Mauron Musy pairs that case with an integrated titanium bracelet, designed as a seamless continuation of the watch’s geometry. Brushed links, polished hexagonal accents and a butterfly clasp underscore the industrial-luxury character, while an additional rubber strap is included.
Available in three color ways, Sunburst Blue, Grained Silver, or Anthracite, the collection plays on the sophisticated contrast between titanium and 18-karat gold hands. This edition remains limited to 100 pieces for the year 2026. Each watch sells for CHF 48,000.
