The countless optimization of mechanical timepieces and the invention of new functions have made this ‘inconspicuous’ small object on the wrist more and more incredible. Roger Dubuis, a high-end watch brand, is the pioneer in the pursuit of accurate timekeeping. In 2013, the brand developed the world’s first superb timepiece equipped with four balances and five differentials—Excalibur Quatuor IV. The balance spring watch, in theory, improves the accuracy of the travel time and proudly displays the magical charm of precision machinery.

Four hairsprings: the ‘quartet’ on the watch
Roger Dubuis Excalibur Quatuor
As the world’s first four balance spring watch, the balance on the Quatuor timepiece, like four musicians, perform elegant quartet movements on the dial for the viewer. In order to better power the watch, each balance wheel is set to a tilt of 45 ° and then works in pairs. Each pair of balance wheels is connected to a differential to average out the position error caused by gravity. It is then averaged out of position with another pair of balance wheels. This design is used to offset the running error caused by the position change. In short, the four balance wheel device can offset the gravity of the tourbillon for one minute in a short period of time, making the time of the watch more accurate.
