The essence of the expressive singularity of the Excalibur collection, the Excalibur Monobalancier skeleton calibre is the latest horological masterpiece unveiled by Roger Dubuis in Geneva in two editions – a diamond-studded one for ladies, and an Eon Gold one for the gentlemen
The last in the evolution of the Excalibur collection is the new Excalibur Monobalancier. The timepiece is enhanced with a series of mechanical and aesthetic improvements that give birth to a sophisticated creation of contemporary flair. The new RD 720SQ calibre has an increased power reserve of 72 hours. Meanwhile, the micro-rotor is optimised to minimise its vibrations, and crafted from pink gold 750/1000 and Tungsten finished with an engraving of the Roger Dubuis’ monogram to modernise its design.
Doubling the balance wheel inertia means improved stability and less sensitivity to shocks. Better efficiency and energy transmission is achieved by optimising the shape of the escapement wheel, now constructed from diamond-coated silicon, and paired with adjustable, diamond-coated silicon pallet-stones, and a new lube. The timepiece features clean-cut lines, fluted bezel, and sharp notches, while the signature star is reshaped to levitate freely above the barrel. This 42mm timepiece includes highly contrasted decorations such as sand-blasted, satin-brushed surfaces, and polished angles. Two editions are available, one with an Eon Gold case and an embossed black calf-leather strap, the other also in Eon Gold and adorned with 60 round-cut diamonds and an embossed purple calf-leather strap. Both straps feature a patented Quick Release System to ensure ultimate versatility for the wearer.
