MOVEMENT

The “fusee and chain” system is a centuries-old mechanism that provides constant force transmission in a movement. It features miniature chain is coiled around a conical “fusee” and attached to the mainspring barrel. As the mainspring unwinds, more of the chain wraps around the barrel, coming off the wide conical bottom of the fusee.
The greater turning movement provided by the fusee compensates the weakening mainspring pull, keeping the torque and, consequently, the amplitude of the regulating organ constant throughout the duration of the mainspring’s autonomy. By combining the fusee and chain mechanism with a tourbillon regulating organ, Zenith places precision at the forefront of its unique take on haute horlogerie, with a uniquely modernistic design language.
