THE MOVEMENT

The Sequential One hand-wound mechanical movement built by us at MCT is more complicated than a tourbillion. There are 471 pieces in this ingenious mechanical movement. The energy requirement to drive the movement, spin the sapphire Minutes disk and turn the prisms presented Denis and the design team with a horological challenge. They mastered the challenge by producing this complex but highly reliable movement which is powered by hand-winding. A sophisticated anchor clutch is included, which 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. When fully wound, Sequential One has a power reserve of 40 Hours.

Sequential One features the enchanting and extraordinary Straumann Double Hairspring Balance which controls the rythym and equilibrium of the movement. This innovative escapement has two balance springs oscillating against each other. The springs are manufactured as a matched pair under optimal conditions. This process ensures the total elimination of gravitational error arising in these springs as they oscillate.
