H101 Resonance comprises two completely independent regulators housed within the same case. The concept of the double regulator was previously explored by Abraham-Louis Breguet (1747-1823) and by Antide Janvier (1751-1855), both of whom made examples. Breguet's famous longcase double regulator (sold to George IV in 1825) is in the Royal collection (see George Daniels, The Art of Breguet, Sotheby Parke Bernet, 1975, pp.82-85 and pp.254-255); an example by Janvier is in the Musée Paul Dupuy, Toulouse.
The phenomenon of the synchronized movement of two pendulums has been known since Huygens wrote of it in the 1660s. After setting the pendulums in motion they settle into a mode where they swing in opposition (a phase shift of 180 degrees). Although there is no connection between the clocks they remain synchronized and the oscillation of two pendulums in resonance has a stabilizing effect on the timekeeping of both clocks.
The original H101, a collaboration between the physicist Stephan Gagneux and the watchmaker Beat Haldimann was exhibited at the Basel World Watch & Clock Fair, spring 2000.
