Roger Dubuis is introducing another Blacklight Edition model, the Excalibur Blacklight Spin-Stone Monobalancier. Although the novelty remains true to its line with Roger Dubuis’ signature skeletonised dial, the new Hyper Horology watch is already a true pioneer of the collection thanks to its implementation of a novel synthetic process.
The case of the Excalibur Blacklight Spin-Stone Monobalancier has a diameter of 42 mm and is made of EON gold. Precious stones that shine in a vivid spectrum of colours decorate the bezel and the flange. The red and blue colour of the gemstones is created by a SuperLumiNova coating that fluoresces both during the day and at night, as well as under UV light. To achieve evenness and luminescence of the stones, the so-called spin-stones were grown synthetically in a special method. This innovative concept of stone refinement is a novelty and has been patented by the manufacture.
The 3D spinels that appear on the dial form the striking frame of the calibre. Micro-rays of different colours form the shape of Roger Dubuis’ signature star. At its centre is a fluorescent diamond for added impact. Meanwhile, the Excalibur Blacklight Spin-Stone Monobalancier‘s hands in pink gold have a brushed surface.
This pioneering Excalibur watch is powered by the RD720SQ calibre, which is composed of 178 components. The movement has a power reserve of 72 hours, a height of 5.95 mm and operates at a frequency of 4 Hz. The improved micromotor of the Excalibur Blacklight Spin-Stone Monobalancier minimises the vibration of the movement. In order to design a movement that is less sensitive to shocks, the inertia of the balance was doubled. The shape of the escapement has been optimized to achieve greater efficiency in energy transmission.
The Excalibur Blacklight Spin-Stone Monobalancier comes with a calfskin strap that can be replaced at any time using the quick-change system. The number of pieces of the Excalibur is limited to 28. Interested parties can purchase the timepiece for 167,500 euros.
