GREUBEL FORSEY QP À ÉQUATION
Greubel Forsey made only five copies of this piece whose mechanism is extremely complex. Its perpetual calendar is controlled in the simplest possible manner by the crown, and you can adjust functions backward or forward. Readability is also magnificent: At 3 o’clock, the day, date and month can be seen at a glance. It includes a 24-Second tourbillon with 25 degrees tilt and an equation of time to find out the real solar time (separate the average time for an interval ranging from several seconds to more than 16 minutes). The equation of time is clearly visible in the rear of the watch and provides information about the difference between solar time and half hour, the seasons, the solstices and equinoxes, and the year in four digits. White gold case. Automatic Calibre GF07 with 72 hours of power reserve. In an alligator leather strap.
