The pair's newly available KB2 clock, for Kontwaz Bauhaus 2, is a pendulum floor clock in the tradition of the Besancon region. The six-foot-tall, key-wound KB2 is easily recognizable as a Silberstein creation. What's harder link to see link is Silberstein's hand in redesigning Lebru's in-house movement. Not only has Silberstein customized the decoration of the escapement and wheels, he's also link tweaked the winding system with a new grooved barrel for improved winding.

That might not be the most significant change here however. Thanks to the link new HMC caliber 500 the watch has been made slightly smaller having been shrunk by 1mm link in width and 0.9mm in thickness. This new 100 in-house micro-rotor movement is made by H. Moser's and measures 30mm by 4.5mm thick making it the brand's smallest movement of the 21st century. With a heavy platinum rotor and smaller slimmer components the movement also link offers 74 hours of power reserve.
