Depending on the light, the new Excalibur Monobalancier Cobalt unveils unexpected radiance. The blue finish of the movement echoes the organic appearance of the alloy, while the silvery cobalt case is even brighter than white gold. 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.
