On their latest celestial voyage, Roger Dubuis and Dr. Woo combine forces to launch the third episode in their Excalibur watchmaking odyssey. This time, the journey goes on a galactic peace mission, finding inspiration in the unimaginable depths of space, while transporting the Maison and the iconic tattoo artist to a new dimension of innovation and creativity.
By working closely together once again, they have created this new collaborative timepiece delving further into realms of decorative originality and showcasing mechanical excellence. For this third episode, Roger Dubuis and Dr. Woo travelled 31 million light years into space, finding inspiration in a distant realm known as the “Tourbillon Galaxy.” Also named Messier 51a, or the Whirlpool Galaxy, this spiralling formation was photographed by the James Webb Telescope in August 2023, revealing its striking arms that play an important role of star-formation factories, creating clusters of new stars.
At 1 o’clock, the complexities of space are expressed once more. The circular barrel cover has been given a matt black background, with additional transfers in pink gold representing the planets, rings, and nebulae within a distant galaxy. This striking pattern moves at the same rate as the barrel, evolving throughout the day to reveal the galaxy from different angles. This also occurs at a faster rate when the watch is wound via its crown.
The Manufacture’s Caliber RD515 (certified by the Poinçon de Genève) features the revered tourbillon, a mechanism that highlights the horological expertise of Roger Dubuis. Signature details such as a flying tourbillon positioned at 7 o’clock are seen in this movement. Yet, to make Dr. Woo’s wondrous vision a reality, Roger Dubuis’ watchmakers have slightly transformed its structure: while the lower cage remains in lightweight titanium, the upper bridge has been reduced to its most minimalistic shape (with just three arms) in order to house a spiral inspired by the Tourbillon Galaxy. This pattern is specifically created in stainless steel, as it’s the best material for the complex shape and also allows Roger Dubuis to perform its signature mirror polish to create a gleaming finish.
