1. Brand Innovation and Philosophy
Ulysse Nardin once again challenges traditional watchmaking aesthetics, presenting the ultimate fusion of visual design and mechanical creativity with the Blast Free Wheel Maillechort. The brand continuously explores new possibilities between structure and art, transforming mechanical movement into a flowing sculpture on the wrist.
2. Architectural “Floating” Design
- The 45mm white gold case, just 12.4mm thick, features a blend of satin-brushed and polished finishes, emphasizing its dynamic lines.
- The transparent sapphire crystal caseback offers an unobstructed viewing experience from multiple angles, with each mechanical element appearing to float in mid-air, breaking the limitations of traditional dial structures.
3. Core Movement and Mechanical Details

Calibre UN-176 Manual-Wound Movement
- 246 components, the result of two years of research and development, oscillating at a frequency of 2.5Hz (18,000 vibrations per hour). – The dual mainspring barrels are suspended in a “floating” layout, with one barrel exposed at 12 o’clock and the other concealed within the movement. Precision ball bearings ensure alignment and stability.
Innovative 7-Day Power Reserve Display
- The power reserve indicator is displayed on a rotating disc at 4 o’clock, using a static indicator that interacts with the dynamic disc. Three full bands indicate a full winding, while one band indicates the power reserve is nearing depletion.
Flying Tourbillon and Patented Constant Escapement
- The flying tourbillon at 6 o’clock is equipped with the 2015 award-winning Anchor Constant Escapement, which utilizes 45 components and two ultra-thin silicon leaf springs to achieve continuous and precise power delivery.
- Silicon material technology eliminates the need for jeweled bearings and an anchor escapement, significantly reducing friction and energy consumption and improving stability.

4. Movement Architecture and Practical Experience
- The left side houses the intermediate wheel, power reserve differential, and reduction gear; the right side houses the winding and time adjustment mechanisms, allowing the user to easily switch between functions. – All flying components are suspended symmetrically from the surface, creating a rich mechanical layering.
5. Maillechort Dial and Material Aesthetics
- The dial is made of Maillechort (a German silver alloy), a blend of copper, zinc, and nickel invented in the 19th century. Its warm, matte texture becomes more distinctive with age.
- Maillechort is highly hard and difficult to manufacture, requiring meticulous craftsmanship. Over time, it develops a unique oxidized texture, adding a unique touch of wear.

6. Wearing and Limited Edition Information
- The watch is fitted with a blue velvet rubber strap for comfort and visual appeal.
- Limited to 50 pieces worldwide, each priced at CHF 120,000 (approximately €128,100), highlighting its collector’s rarity and the brand’s status.
The Blast Free Wheel Maillechort represents Ulysse Nardin’s redefinition of the limits of mechanics and aesthetics: the flywheel, mainspring, and power reserve indicator are all suspended in mid-air, creating a harmonious interplay of materials and craftsmanship. Every glance is like stepping into a suspended realm of mechanical art; every careful appreciative glance reveals the ingenuity and contemporary spirit between movement and stillness. For collectors who value innovation and unique aesthetics, this watch is more than just a watch; it is a fluid piece of contemporary art.
