Roger Dubuis Excalibur Diabolus in Machina (New Models in Pink Gold and DLC-coated Titanium)

Roger Dubuis presents two new editions of its high complication watch, the Excalibur Diabolus in Machina. Now available in pink gold and DLC-coated titanium, this hyper horology creation incorporates a minute repeater, alongside the Geneva Maison’s signature flying tourbillon, as well as a double micro-rotor automatic system.

Its minute repeater chimes the tritone, the “Diabolus in Musica” chord outlawed in medieval religious music. The Excalibur Diabolus in Machina also features two other functions: a tone playback disc indicator and an “all or nothing” safety device.

The Excalibur Diabolus in Machina was introduced in 2020. The inaugural model features CarTech Micro-Melt BioDur CCMTM case. Roger Dubuis Excalibur Diabolus in Machina

The Excalibur Diabolus in Machina has a push-piece for activating a chime. The information on each cam is mechanically read off by the Minute Repeater’s main feeler-spindle system, which passes it on to the racks enabling the hammers to strike the gongs. The latter sounds a low pitch for the hours, a high pitch for the minutes, and two tones for the quarter hours, allowing the wearer to check the time at will. Consisting of three tones, or six semitones, the tritone – also known as the triad or the flatted fifth – an unsettling interval that does not conform to listeners’ expectations.

This distinctive dissonance was referred to in medieval times as “the devil’s chord” or diabolus in musica and strictly prohibited in religious compositions. It has nonetheless continued to play a crucial role in complex melodic harmony, notably appearing in Camille Saint-Saëns’ symphonic poem Danse Macabre and in the signature tune of the Black Sabbath metal band.

Cleverly shaking up the world of minute repeaters, Roger Dubuis has chosen the sound of the tritone as the chime of its Minute Repeater in the Diabolus in Machina. Pressing the minute repeater button between 9 and 10 o’clock activates the dissonant tonality – tuned to C and G flat – resounding through noble materials and providing a fascinating listening experience.

Various key technical advances featured in the Excalibur Diabolus in Machina include the Tone Playback Disc Indicator at 11 o’clock. Activating the Minute Repeater sets off the rotation of this disc – merged with a Roman numeral and bearing the words Hours, Quarters and Minutes. The result is a visually striking depiction of the time intervals being chimed.

An additional functional indicator further simplifies usage by showing whether the watch is in “manual winding” or “time setting” position. As well as enhancing the design through its artful integration at 4 o’clock, it plays a useful safety role in avoiding potential damage by warning the wearer not to adjust the watch while the Minute Repeater is chiming.

The “all or nothing” mechanism offers additional security by ensuring the minute repeater can be activated only once the pusher has been pressed all the way in. This eliminates the risk of harming the mechanism by inadvertent triggering, as well as facilitating comprehension of the chime by avoiding any partial and potentially confusing indications of time.

The intricate complexities of this model are naturally heightened by Roger Dubuis’ typically bold decision to combine this fresh approach to the minute repeater with its signature flying tourbillon. Each of these two horological complications involves its own technical challenges and associating them within the same model is the kind of endeavour reserved for the most skilled and experienced master-watchmakers.
