QP à Équation
"On Wednesday 08 November 2017, the Jury of the Grand Prix d’Horlogerie de Genève has awarded the ‘Calendar Watch Prize’ to the QP à Équation...
by Greubel Forsey. At the heart of the QP à Équation lies Greubel Forsey’s seventh invention, the Mechanical Computer. 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 movement side, this timepiece displays the equation of time with the months, seasons, solstices and equinoxes, as well as the calendar year."
