A new version of our iconic RD820SQ caliber with a decor made possible thanks to a technology used for one of the first times in the watchmaking industry. Sapphire microtubes are displayed throughout the calibre making it a mechanical sculpture. In addition to that, the tubes will glow under UV light, revealing the motif as if was floating in the case at night.
