Roger Dubuis Excalibur Tourbillon watch. This timepiece is known for its high-end horology and distinctive design. The watch features a flying tourbillon, a complex horological complication where the tourbillon cage is supported only from one side, giving the impression of it "flying". It houses the Calibre RD512SQ, an optimized movement with a 72-hour power reserve. The design is characterized by its signature elements, including the placement of the tourbillon at 7 o'clock and an upper cage inspired by the Celtic Cross.
