Roger Dubuis introduces the fourth timepiece from its Urban Culture Tribe created in collaboration with sculptor, drawer, and painter Liu Wei. The Excalibur Liu Wei Monotourbillon is a creative representation of the lively and intricate urban world.
Liu Wei’s rule-breaking masterpieces have been exhibited at the most renowned museums and exhibitions around the globe. The artist grew up in a period of accelerating urbanisation, and this rapid evolution inspires much of his art, including his famous “Purple Air” series.
To bring Liu Wei’s vision to life, Roger Dubuis’ watchmakers imagined a three-layer solution. The first layer of décor features a clear sapphire glass engraved with vertical lines on both the front and back. Hand-filled with extreme precision, the watchmakers colored each groove individually. Some grooves are filled with regular lacquer while UV paint is used for others. The balance of painted and glowing lines creates a sophisticated architectural depth under UV light. The selection of shades and their varying effects reflect the artist’s vision of the world’s vibrancy. The second layer features Roger Dubuis’ star signature. To work within Liu Wei’s concept its thickness is reduced and grey structure features distinctive black lines. The third layer features a sapphire glass case-back laser-engraved to create horizontal grooves. Hand-filled with UV paint, this overlap of lines contrasts with the vertical stripes of the first layer.
The hour markers are filled them with black SuperLuminova for a glow in the dark effect, also visible under UV light. The Roger Dubuis and Swiss Made logos are, for the first time, filled with powdered SuperLuminova. This striking feature is silver by day, green by night, and blue under UV light.
The watch is powered by RD512SQ calibre. The power reserve is radically optimised to 72 hours, providing the option of leaving the watch unworn over weekends. Hand-finished with meticulous care, the timepiece is sealed with the Poinçon de Genève.
Limited to just eight pieces, the Excalibur Liu Wei Monotourbillon is housed in a 42 mm titanium grade 5 case and mounted on a black calf leather strap, interchangeable with a Quick Release System.
