This timepiece is created from the rarely used in watchmaking yet highly resistant cobalt chrome. Certified by Poinçon de Genève, the blue skeletonized Monobalancier movement is housed in a brilliant, silvery-grey case in cobalt chrome, while showcasing the Maison’s fine watchmaking expertise and expressivity.Originally used in cutting-edge industries, cobalt chrome is produced through an exclusive micro-melt process. This innovative and rare alloy has become one of Roger Dubuis’ signature materials, bringing together brilliant shades, anti-magnetic properties, and remarkable resistance to scratches and corrosion. Cobalt chrome offers a higher resistance than stainless steel, while its ability of capturing light makes it appear even brighter than white gold. This material choice enhances the durability and aesthetics of the timepiece as the skeletonized architecture of the movement is enveloped in a striking blue hue honouring the natural appearance of cobalt. Depending on the light, this blue finish subtly changes shades, highlighting the astral signature and the Maison’s canvas for expressivity.
