Driven by the forces of gravity and planetary cycles, Roger Dubuis marks a monumental first in the history of watchmaking by uniting the Quatuor and Perpetual Calendar complications. This audacious leap in engineering is not simply a timepiece, but a powerful statement of virtuosity from a Maison that has long defined itself through theatrical high watchmaking. Limited to an exclusive edition of just eight pieces, this creation is designed specifically for connoisseurs who appreciate the intricate relationship between Earth and its celestial neighbours.

At the heart of this showstopping creation beats the in-house calibre RD116, a complex engine built with 758 components. The movement is supported by three distinctive patents, including an innovative gravity compensation system and a unique power reserve mechanism. Reflecting the brand's commitment to ancestral craftsmanship, 14 different decoration techniques are performed by hand on each component within the Roger Dubuis Geneva Manufacture, including mirror polishing and circular graining.

The ingenuity of the Quatuor lies in its radical approach to precision. While a traditional tourbillon averages the effects of gravity by rotating a single balance, the Quatuor instantly compensates for these effects using four balance wheels working in unison. These tilted balances are arranged in pairs at 90-degree angles and connected by a complex system of five differentials. This technical milestone, which required over seven years of research, drives Genevan excellence into alternative realities of performance.

For the Maison's founder, Mr. Roger Dubuis, the Perpetual Calendar was a cherished signature. His patient nature and quiet perseverance were ideally suited to the complication's complexity, which follows the natural rhythms of the cosmos. In this new evolution, the calendar is presented in a classic circular form to align with the aesthetic of the Quatuor's four balance wheels. A key functional upgrade includes a month corrector that allows the month indication to be manually set with one simple adjustment, making regulation faster and easier.

Design at Roger Dubuis is always driven by singularity, as evidenced by the patented one-handed Power Reserve indication at 9 o'clock. This original mechanism features a double 180-degree display where both the indicator and the hand move at different speeds. It provides a purely theatrical performance to signal the watch's remaining energy, ensuring that every function serves as a piece of horological art.

The technical proficiency of the Maison is further highlighted by the use of Cobalt Chrome, a signature material first created for the aeronautical and aerospace sectors. The full 48 mm case is fashioned from this advanced alloy, which offers exceptional scratch resistance and non-magnetic properties. Its striking brilliance is paired with blue accents on the dial and a blue calf-skin leather strap, a nod to the organic colour of cobalt found in nature. Through these precise displays, Roger Dubuis pays tribute to the motion and beauty found beyond our planet.
