QP à Équation

Greubel Forsey reinterprets the Perpetual Calendar with Equation of Time. To this effect, a mechanical computer had been created, which manages all the changes in the displays. The dial side mainly shows the 24 hours of the day and night, the day of the week, the large date, the month, the hours and the minutes; the movement side shows the equation of time and the seasons and the year.

Also available as White Gold, and White Gold with Anthracite Gold Dial editions.
