Greubel Forsey launched its seventh “invention piece,” the QP à Équation, to wide acclaim at SIHH 2015. Now the trailblazing brand founded by Robert Greubel and Stephen Forsey takes this micro-mechanical marvel to the next level of luxury in a new Millésimé Edition with a rhodium-colored gold dial.
The Greubel Forsey QP à Équation Millésimé, like its predecessor, is driven by a movement equipped with an ingenious mechanism that Greubel Forsey calls a ?Computeur Mécanique,? or mechanical computer. This device, for which the brand has received three patents, is a sub-assembly of 25 parts within the larger 424-part caliber, and partly inspired by the systems used in large astronomical clocks since the end of the 15th century, which managed the information that determined certain key dates in the ecclesiastical calendar in relation to astronomical data. The mechanical ?brain? at the center of this invention consists mainly of rotating, co-axial coded elements in an arrangement complemented by a system of programmed movable sections. Depending on its geometry and speed of rotation, each element generates its own indication in a cyclical, pre-programmed way. In this manner, the mechanical computer is able to automatically display all the indications of the watch, each generated by its own co-axial coded element. In the case of the QP à Equation, these consist of all the functions of a perpetual calendar, along with the equation of time: seasons, equinoxes, ...
