Excalibur Quatuor
Carbon with four sprung balances

Ref: RDDBEX0673
Carbon, Black
Limited edition 8 pcs.

A revolutionary approach to compensate the effect of earth’s gravity.

The four sprung balances work together and adjust instantly the gravity effects on the movement when the Tourbillon does it in one minute. As of today, Roger Dubuis is still one of the only maisons to be able to master such a complicated calibre. Made of multi-layered carbon, this Excalibur Quatuor is 60% lighter than the gold version for a better ergonomy.


The Roger Dubuis Quatuor RD101 caliber symbolises the mechanical magic of one of the most innovative Manufactures of the 21st century.

The precision of a movement is affected by the gravity of the Earth as the watch constantly changes position with the motion of the wrist. The four carefully positioned sprung balances work in pairs to compensate immediately for the rate variations caused by the changes in position. What the tourbillon achieves over the course of a minute, the Roger Dubuis Quatuor RD101 caliber achieves instantly.

2,400 hours of manufacturing, including 720 hours devoted to the Poinçon de Genève.

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.
