Quatuor in Silicon

Silicon has been chosen for its uniquely low weight and its incomparable hardness. In fact, it is half the weight of titanium, which is half the weight of steel, yet it is 4 times harder.

Additional detail
Its deep grey colour adds to the exclusivity of this iconic watch. Silicon has a similar atomic structure to diamond and working with it  requires just as much skilled expertise. Roger Dubuis has called on numerous specialists using highly advanced techniques to produce this case in “metallic crystal”.

RD101 movement

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 tourbillon has provided a partial answer to this problem but the Excalibur Quatuor offers a new solution. 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 Excalibur Quatuor achieves instantly.
