F.P.Journe Quantième Perpétuel 40/42mm Platinum Blue Gold Numerals

Quantième Perpétuel 40/42mm Platinum Blue Gold Numerals

Optimum readability and simplified use for the F.P.Journe Quantième Perpétuel with instantaneous jump. The F.P.Journe Quantième Perpétuel (perpetual calendar) displays the exact date by automatically taking into account the variable length of the months and leap-year cycle. A movement able to identify leap years has a real mechanical memory. A small toothed planet wheel connected to the month’s mechanism performs a complete rotation in four years. During the fourth year, this mechanism displays 29 February before directly moving on to 1st of March. Just as the moon moves around the Earth, this planet wheel rotates on its own axis resting on a swivel wheel. This complication, which is both useful and demonstrates technical prowess, is one of the masterpieces of the watchmaking art. The F.P.Journe Quantième Perpétuel with instantaneous jump presents a distinctive aesthetic compared to all existing perpetual calendars in offering perfect readability through an uncluttered dial with large apertures: two for the day and month calendar, and a large date in two windows, a specificity of F.P.Journe watches. The instantaneous jump is reinforced by an ingenious F.P.Journe system designed to accumulate energy and release it instantaneously when the date, day or month changes; and then slow it down at the end of its route.
