Roger Dubuis unveiled the third timepiece from its Urban Culture Tribe. The Excalibur Sorayama Monobalancier was created in collaboration with the world-famous Japanese artist Hajime Sorayama who is famous for his super-realist feminine “Sexy Robots”. The Swiss watchmaker invited him to the Manufacture to reinterpret its star signature.
To create the hyper-sophisticated timepiece, Hajime Sorayama broke the Maison’s design codes. Curvy lines and a full shine finish blur the sharp design and contrasted finishes Roger Dubuis usually marks its masterpieces with. Sorayama took further cues from his own iconic creations by duplicating his 3D sculptures within the polished titanium finish. The artist also reimagined Roger Dubuis’ micro-rotor to create a hypnotizing moiré optical illusion initiated by the natural fluid movements of the wearer’s wrist. This effect required months of in-house prototyping looking for the right combination of materials, decorations and finishes. The final execution associates an extremely precise and optimal distance between each line of the stamped décor, with a traditional three-hour long guilloché technique on specific parts of the micro-rotor and an assembly process placing a stamped sapphire dial above the reimagined micro-rotor.
The Excalibur Sorayama Monobalancier is equipped with an automatic calibre. For this watch, Roger Dubuis’ engineers increased the power reserve of the RD720SQ to 72 hours. They also optimized the micro-rotor to minimize vibrations and doubled the balance wheel inertia to improve stability and make it less sensitive to shocks. Better efficiency and energy transmission were further augmented through the use of a new lube and by optimizing the shape of the escapement wheel, pairing it with adjustable pallet-stones, and constructing both elements from diamond-coated silicon.
This masterpiece is also the first Roger Dubuis titanium grade 5 bracelet to feature its Quick Release System. Housed in a 42 mm case crafted from titanium grade 5 as well, the timepiece is limited to just 28 pieces and at first available in Japan only.
