QP A EQUATION WHITE GOLD ANTHRACITE DIAL 43.5MM MILLÉSIMÉ
At the heart of the QP à Équation lies Greubel Forsey’s seventh invention, the Mechanical Computer, which brings a totally new interpretation to some of the calendar functions incorporated in age-old astronomical clocks. It is composed of a set of coding wheels superimposed in a coaxial manner, as well as removable fingers programmed by this ingenious system.
The dial of the QP à Équation indicates leap years, the 24 hours of the day and night, the day of the week, the large date, the month, the hours, the minutes and the seconds, as well as the chronometric 72-hour power reserve. On the bridge side, this timepiece displays the equation of time with the months, seasons, solstices and equinoxes, as well as the calendar year.
The QP à Équation provides a simplified linear reading. Herein lies the happy paradox of this piece: it is an ultra-complicated timepiece with its tourbillon and its complete equation of time perpetual calendar function, but it is as easy to use and adjust as a watch with three hands. This system is extremely easy to adjust in both directions without damaging the mechanism.

The art of invention
At the core of Greubel Forsey lies a relentless commitment to invention. Since its inception, the Atelier has secured more than 70 patents and introduced ten Fundamental Inventions, each designed to deliver meaningful advancement in mechanical watchmaking. Innovation is approached with purpose, refining chronometric precision, enhancing mechanical performance, and expanding the expressive potential of the timepiece.
This philosophy is embodied in creations such as the Tourbillon Cardan, distinguished by its multi-axis, three-cage construction and fluid, gimbal-inspired motion, as well as the Nano Foudroyante, which incorporates a patented nano-mechanism uniting flying seconds, a tourbillon, and manual-wind flyback functionality within a remarkably compact case. Each development is a stepping stone, forming the basis for continued evolution across the collection.
