A world premiere with a revolutionary approach to compensate the effect of gravity. A seven-year research program is the path to create the Quatuor calibre. The four tilted sprung balances work in pairs at a 90° angle and are linked with five differentials so they can instantely compensate the effect of gravity thanks to the different changes in position of the owner's wrist. What the tourbillon achieves over the course of a minute, the Quatuor achieves it instantly. Most of the automatic calibres in Haute Horlogerie operate at a frequency of 4 Hz. The Quatuor movement raises the bar much higher with a frequency of 4x4 Hz. As of today, Roger Dubuis is still one of the only maisons to be able to master such a complicated calibre. Made of multi-layered carbon, this Excalibur Quator is 60% lighter than a gold execution for a better ergonomy.
