Introducing the Roger Dubuis Excalibur Quatuor. Presented in a 48 mm rose gold case (shown) or a limited edition silicon case, the Excalibur takes the brand’s premiere watch collection, to the next level.
The Excalibur Quatuor dial is dominated by the four visible balance wheels, and with and hour and minute dial in the center. The balance assemblies are mounted at 45 degrees (they do not rotate like tourbillons). The escapements work in pairs to compensate immediately for the rate variations caused by the changes in position. Five differentials link the balances to the gear train, smoothing out the influences of gravity in real-time.
