Roger Dubuis has unleashed the full potential of colourful luminescence with the new Excalibur Blacklight Spin-Stone™ Monobalancier, a creative timepiece takes the Maison’s watchmaking to unconquered limits, where every detail has a scintillating effect.

Roger Dubuis’ Blacklight collection has already gained an iconic reputation for its aesthetics and performance, and with the latest generation presented today, the visionary Spin-Stone™ edition enters another era. Powered by the RD720SQ calibre, and glowing with artistic originality, this is a timepiece that demands attention.

Colors of Innovation

The vivid spinels that adorn this Hyper Horology™ creation catches the eye makink you fall in love at this timepiece first sight. Graded from red to blue, and coated with Super-LumiNova™, each spinel is shining in full colour – whether by day, by night, or under UV light. This multi-toned effect gives the watch its chromatic look, and shows Dubuis’ passion for the art of luminescence.

Each spinel has been synthetically grown in order to achieve the exact shades, uniformity, and luminescence desired, using a challenging technique that ensures colour and light blend perfectly to attain the most flawless results. The visible spinels that encircle the bezel and flange – the Spin-Stones™ are an innovation of the Maison; this world premiere stone-cut and sculpted with their own signature curves and sharp angles is patent pending, and yet again demonstrates Dubuis’s ability to exploit aesthetic design in its most spectacular form. The calibre’s eye-catching framework is comprised of its own 3D spinels, colourful micro-beams of light reach out to form the branches of Roger Dubuis’ iconic star – which is neatly punctuated at its heart by a naturally fluorescent diamond which adds one final touch of brilliance.

Performance is a must

Balancing aesthetics and performance, the automatic RD720SQ calibre has an increased power reserve of 72 hours and an optimized micro-rotor to minimize the vibrations. To further improve stability, the balance wheel inertia has been doubled – making the watch less sensitive to shocks. The shape of the escapement has been enhanced, paired with diamond-coated silicon pallet-stones and a new lube for greater efficiency and energy transmission. This display of Roger Dubuis’ obsessive engineering is brought together with hand-finished quality and meticulous care – all resulting in the Poinçon de Genève certification, one of the most demanding signatures of fine watchmaking.
