Roger Dubuis Excalibur Grande Complication

Thirty years after the celebrated watchmaker Roger Dubuis founded his eponymous maison, and 16 years after it introduced its first grand complication, the brand is back with a second grand comp that, much like its predecessor, features a perpetual calendar, a minute repeater, and an automatic tourbillon. Brimming with 684 components, the timepiece improves on the original in subtle but meaningful ways: The perpetual calendar, for example, features a biretrograde display, which allows the calendar’s hands to move along the semi-circle scales, before immediately returning to zero at the end of their cycle. The minute repeater plays a dissonant tritone chime known in medieval times as “the devil’s chord" or the “diabolus in musica," but now prized for its nuance. And the tourbillon, like all Roger Dubuis examples, boasts a flying construction, in this case enclosed within a mirror-polished cage inspired by the Celtic Cross. And let’s not forget: The model, as with the brand’s entire production, is blessed with Poinçon de Genève certification, a trusted marker of origin, superior functionality and horological precision.
