Mauron Musy Debuts the MU09 NODE° with Its First Manufacture Micro-Rotor Movement
The new Grade 5 titanium model debuts the brand’s proprietary Calibre MM03 micro-rotor movement and first integrated bracelet
Mauron Musy introduces the MU09 NODE°, a new 41mm Grade 5 titanium watch that marks several firsts for the Swiss independent brand. The model debuts the proprietary Calibre MM03, introduces the haute horlogerie brand’s first integrated bracelet, and continues its use of nO-Ring— the patented gasket-free sealing system that has defined Mauron Musy since its start.
Founded in 2013 by Christophe Musy and Eric Mauron, Mauron Musy is based in Switzerland’s Broye Valley, outside the country’s more traditional watchmaking centers. The brand first built its identity around an unusual technical premise: creating water-resistant watches without elastomer gaskets. That system became nO-Ring, a mechanical sealing technology that informs both the construction and design of its cases.
With the MU09 NODE°, Mauron Musy moves that technical story further toward the movement itself. Inside the watch is the Calibre MM03, the brand’s own proprietary self-winding micro-rotor movement.. Composed of 232 components and 32 jewels, the caliber runs at 28,800 vibrations per hour and delivers a power reserve of 96 hours, or four days, by way of a tungsten micro-rotor.
The movement is partially visible through the semi-open dial architecture, where the balance bridge is positioned at 9 o’clock alongside the small seconds display. The layout gives the watch a controlled, asymmetrical appearance, with central hours and minutes serving as the primary indications. The MM03 also features a Swiss lever escapement, free-sprung balance with inertia screws and traditional chaton settings for its large-jewel bearings.
The case is made from Grade 5 titanium and measures 41mm in diameter and 13mm thick. Its construction uses 24 components and the brand’s nO-Ring mechanical sealing system to achieve 200 meters of water resistance without traditional gaskets. The case is finished with brushed and polished details and fitted with sapphire crystals with hard anti-reflective coating.
The MU09 NODE° also introduces Mauron Musy’s first integrated bracelet. Made from the same Grade 5 titanium as the case, the bracelet combines polished, microblasted, and satin-finished surfaces with a butterfly clasp. A rubber strap with folding clasp is also included.
The collection will be offered in three references: MU09-101 with an anthracite ruthenium grained dial, MU09-102 with a silver grained dial and MU09-103 with a sunburst blue dial. Each version is available with either solid 18k rose-gold or rhodium-plated hands.
The Mauron Musy MU09 NODE° will be offered in a limited allocation of 100 pieces in 2026. Pricing is listed at CHF 48,000.
