Quantième Perpétuel 40/42mm Red Gold Silver Dial Gold Numerals

Optimum readability and simplified use for the F.P.Journe Quantième Perpétuel with instantaneous jump.

During the 18th century, astronomical watches gradually gave way to the manufacturing of watches showing the date and, usually, the moon phases. These primitive calendar watches were all of the simple calendar type, that is to say, that at the end of each month of less than 31 days, the days hand had to be put forward manually. Adding to the movement the complicated mechanism of a perpetual calendar, in which, every four years, the 29th of February would be automatically recorded, had long been the dream of every watchmaker.
