Ulysse Nardin unveils the enigmatic charm of the Blast Free Wheel Maillechort

1 December 2025

By Kien Lee

In the world of haute horlogerie, Ulysse Nardin has long reigned as a master of mechanical theater, and their latest creation, the Blast Free Wheel Maillechort, is a breathtaking exercise in transparent mastery

 This timepiece is as much a question mark as it is a chronometer, a visual spectacle designed to defy perception and redefine the very boundaries of engineering. It is one of the most complex and visually stunning pieces the Manufacture has ever conceived, limited to an exclusive run of just 50 pieces.

The drama of the Blast Free Wheel lies in its mysterious complication. The mechanics appear to float in mid-air, leaving the observer to wonder how the components truly work without visible connections. The architecture is housed within an ultra-glass box, a sapphire crystal structure that provides an expansive, wide-open view of the 'floating' movement.

The dial is crafted from Maillechort, a traditional alloy of copper, zinc, and nickel that is prized for its warm, deep tones and unique texture. This beautiful material is contrasted against the technical prowess of the caliber which includes a groundbreaking flying tourbillon. This mechanism, first introduced in 2015 and a winner of the GPHG Tourbillon Award, is one of the world's first to use silicon for its constant force escapement. This material innovation ensures flawless precision by minimizing energy loss and delivering constant power to the time-telling components.

The design of the watch is a celebration of both power and elegance. It features a flying double-barrel system which delivers an impressive 7-day power reserve. The case itself is a study in refined contemporary design, allowing the mesmerizing depth of the movement to take center stage.

The Ulysse-Nardin Blast Free Wheel Maillechort is more than a timepiece; it is a wearable piece of architectural mystery, confirming Ulysse Nardin's legacy as a pioneer of material science and mechanical daring.
