Excalibur Diabolus in Machina

Roger Dubuis 2020

ref. RDDBEX0842
Men's

A name not generally associated with grandes complications, Roger Dubuis presents this complex execution of its Excalibur with, this being Roger Dubuis, a flying tourbillon but also a minute repeater; one of the most complex mechanisms in watchmaking. To spice things up a little, the brand has included a striking indicator, a function indicator and an "all or nothing" pusher for the repeater, which is tuned to a tritone: the medieval diabolus in musica. The case of this Haute Horlogerie watch is made from cobalt chrome, an alloy whose hardness makes it notoriously difficult to machine but one that Roger Dubuis has chosen nonetheless as its homogenous composition allows sound to disperse harmoniously. These high mechanics are reflected in the sharp design; the brand's signature star acts as a bridge, imploding dial-side to create an impression of chaos.
