THE MCT MOVEMENT

The S1mechanical movement is assembled at MCT and is more complicated than a tourbillion. There are 471 pieces in this ingenious movement. The energy required to drive the movement, spin the sapphire Minutes disk and turn the prisms, presented Denis and the design team with a major horological challenge. They produced a hugely complex but reliable movement which is powered by hand-winding. A sophisticated anchor clutch prevents over-winding. The special system that accumulates and stores power for the rotation of the disk is subject to a patent. Energy is constantly being drawn from the movement and it takes one hour of energy accumulation to power a single 90° rotation of the Minutes disk. S1 has a power reserve of 40 Hours.

Sequential One features the extraordinary "Straumann Double Hairspring Balance" which regulates the escapement and ensures the total elimination of gravitational error.
