Roger Dubuis Excalibur Orbis in Machina Moonlight

Roger Dubuis presents the Excalibur Orbis in Machina Moonlight, reference RDDBEX1221, a 45 mm titanium case with DLC treatment. The case measures 12.2 mm thick and carries the Genevian Seal, a mark reserved for movements finished to Geneva's own standard. Inside is the manual-winding calibre RD115, a central flying tourbillon with 72 hours of power reserve. The tourbillon cage sits at the centre of the dial rather than off to one side, with a hand-engraved lunar surface texture crowning it. This is a limited edition, produced in a run of 277 pieces. It comes on a blue calf leather strap fitted with a titanium folding clasp finished in black DLC. Water resistance is rated to 50 metres, modest for a piece built around such a complex display.
