Mechanically programmed to cope with the irregularities of our Gregorian calendar up until the year 2100, the perpetual calendar is one of the major complications of the watchmaking art. Piaget Calibre 855P self-winding movement displays the hours, minutes, small seconds at 4 o’clock, month and leap years at 12 o’clock, along with retrograde day of the week and date displays at 9 and 3 o’clock respectively. In addition to the latter retrograde indications, this Calibre 855P stands out from most ordinary perpetual calendars by the addition of a dual time-zone display appearing in a subdial at 8 o’clock. The self-winding Piaget Calibre 855P is endowed with an approximately 72-hour power reserve.
The decorative features such as circular Côtes de Genève and blued screws match the brand’s aesthetic signature codes, while the oscillating weight is adorned with the Piaget coat-of-arms.
