Piaget Emperador Coussin Perpetual Calendar

Caracteristics

Description

The subtle architecture of the 46 mm case enables it to adapt to all wrists and imparts a particularly elegant profile. In line with Piaget’s determination to combine horological complications with user-friendliness, the case middle actually carries a mention of the function of each of the four correctors for the month, date, day of the week and second time zone.

Subtly alternating polished and satin-brushed surfaces on the case middle, bezel and inner bezel ring, the case of the Piaget Emperador coussin Perpetual Calendar is fitted with a sapphire crystal back providing admirable views of the movement finishes. The plate and bridges are circular-grained, bevelled and drawn out with a file. 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.  Measuring 5.6 mm thick, the Manufacture Piaget Calibre 855P self-winding movement was designed, developed and produced entirely in-house. It 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 double-hand dual time-zone display appearing in a subdial at 8 o’clock. The self-winding Piaget Calibre 855P beats at a cadence of 21,600 vibrations per hour and is endowed with an approximately 72-hour power reserve.
