Quatuor

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.
