Evolution 3-1

Evolution 1-3 tops off the broad range of world firsts which have forged the reputation of the brand over the years.

Triaxial tourbillon

The originality of the triaxial tourbillon is that two frames as well as the tourbillon are set in motion on three different perpendicular axes. So it is that, in an hour, being how long it takes for the first frame to complete a revolution, the tourbillon will have passed through all possible positions and will have compensated for any possible running variations. To obtain this result, a double barrel, acting through the minutes wheel, drives a first frame which completes a revolution in one hour. The second frame, driven by the first, completes one revolution in eight minutes. The tourbillon, carrying the escapement and the balance-wheel, is driven by the second frame and completes a revolution in sixty seconds. Apart from the great ingenuity of the design, the true connoisseur of the watchmakers art will appreciate the virtuosity inherent in the realization of the tourbillon movement. Its stunning beauty is the result of one of the most difficult exercises in the luxury watchmaking industry.

Power reserve

An ingenious power-reserve mechanism actuated by the barrel ar-bour (patented by Franck Muller) makes it possible to indicate, with a hand placed at 12 oclock on a scale graduated from 0 to 10, how many days power reserve remain.

Perpetual calendar

The calendar mechanism, just as the basic movement, is entirely designed and manufactured in Watchland. Its special characteristic lies in a design very different from that of the traditional calendar mechanism, in order to allow the tourbillon to be visible through the dial, as in all other Franck Muller movements. Besides this differ-ence, the mechanism allows for all calendar indications, that is to say:

Movement: Manually-wound mechanical movement. Triaxial tourbillon. Perpetual calendar with moon phases. Power reserve indicator.
