At Roger Dubuis, pushing the boundaries of watchmaking is in the very DNA of the Maison. Inspired by the visionary spirit of its founder, Mr. Roger Dubuis, who was captivated by the world of horological complications, the brand has always sought to evolve and elevate these intricate mechanisms. In 2009, the watchmakers at Roger Dubuis introduced their first 100% in-house Grande Complication calibre—a bold step in the world of luxury watches. This highly coveted title is reserved for timepieces that feature at least three advanced complications, and the RD0829 was no exception. It included a perpetual calendar, a minute repeater, and a flying tourbillon double micro-rotor, three of the most prestigious complications in watchmaking.

Now, in 2025, Roger Dubuis unveils its second Grande Complication calibre, the Excalibur Grande Complication. This remarkable timepiece continues the legacy, beautifully blending a perpetual calendar, minute repeater, and automatic tourbillon into a single, refined movement. The new Calibre RD118 offers an impressive 60 hours of power reserve, while its intricate finishes and hand-decorated components elevate it to a level of unmatched craftsmanship.

The attention to detail required for the esteemed Poinçon de Genève certification ensures that every one of the 684 components is meticulously decorated by hand. This prestigious certification is not only a mark of horological precision but also a guarantee of origin, sublime functionality, and unparalleled artistry. The Excalibur Grande Complication is a true testament to Roger Dubuis’ commitment to pushing the limits of watchmaking excellence.
