Everyone knows that the devil is in the details. And because creative irreverence is a temptation that Roger Dubuis finds irresistible, Excalibur Diabolus in Machina pushes sophistication to breaking point. 
Roger Dubuis has chosen to tune its minute repeater to the sound of the tritone, the famous “Diabolus in Musica” chord outlawed in medieval religious music, the secret key to all clever and complex melodic harmony. 



Two of the most admired complications combined into one calibre.

A minute repeater coupled with a flying tourbillon, the RD107 is a blend of haute horlogerie made possible thanks to the highly skilled watchmakers of Roger Dubuis.

Three different indicators - functions, all or nothing, chiming - are displayed on the upper side of the calibre.

The RD107 is powered by two micro-rotors visible on the back of the calibre.

About Complication

An automatic timepiece is a mechanical watch set with either an oscillating mass or a micro-rotor which, thanks to the natural wrist movement winds itself mechanically. Therefore, if worn everyday, the timepiece doesn’t need hand winding. 

A manual timepiece is a mechanical watch that needs to be hand-wound to function. The several mouvements have a “power reserve” that determine the length of time the watch is able to function with its full wound capacity. Especially appreciated from specialist of “Haute Horlogerie”.

A tourbillon is an addition to the mechanics of a watch escapement. In a tourbillon the escapement and balance wheel are mounted in a rotating cage, in order to negate the effects of gravity when the timepiece (thus the escapement) is stuck in a certain position. 

A masterpiece from Roger Dubuis. The achievement of 7 years of research and 40 people included in the production process of the watch. A timepiece working with 4 balance sprung and 5 differentials, for an ultimate precision. A watchmaking achievement that looks for the untouched territories of mechanical accuracy. 

The minute repeater is a timepiece that once mechanically pushed, rings the hours, quarters and minutes of the watch. It is an historic complication that is known for the mechanical achievement of making a mechanical timepiece ring.
