Roger Dubuis Excalibur Quatuor

Roger Dubuis Excalibur Quatuor

One of the world’s most exclusive luxury timepieces for sure is the Roger Dubuis Excalibur Quatuor, and it houses the world’s first watch movement with four sprung balances. Roger Dubuis are the only manufacturer that bear the Geneva stamp on each of their watch movements.

The Excalibur Quatuor looks absolutely amazing but it also sounds brilliant because the unique sound emitted is the result of four separate balances each oscillating at 28,800vph, all of which are set at a 45-degree incline. The ticking of a classic watch is now replaced by the gentler sound of truly high precision. Designed by lead Roger Dubuis movement designer Gregory Bruttin, the caliber RD101 movement in the Quatuor is unlike most things you’ve seen before. Calibre RD101 focuses on efficient power flow. There are total of five differentials, three on the gear train, one influencing the winding mechanism, and another on the power reserve display.

As the watch constantly changes position with the motion of the wrist, the precision of a movement is affected by the gravity of the Earth. The sprung balances work in pairs to compensate immediately for the rate variations caused by the changes in position. Wonderful decoration by hand of all the 590 components of the calibre RD101 is a real piece of art. 2,400 hours of work have been invested to bring this watch to life.

As you probably already know that the Excalibur Quatuor is available in two versions, in pink gold and silicon. But now there is a third model in DLC-treated titanium. Its 48 mm case remains light thanks to the use of titanium, and it also exudes an elegance enhanced by the charcoal grey inner bezel ring, circular satin-finish outer bezel ring, Roger Dubuis and Poinçon de Genève inscriptions, along with the rhodium power-reserve indicator and black appliques. Made in a limited edition of 188 pieces, this stunning new model launched specially for Watches & Wonders could be yours for €575,000.
