Exclusive: SIHH 2016 Patrimony Perpetual Calendar CEP

from the press release


Patrimony Perpetual Calendar Collection Excellence Platine


A stellar complication – the perpetual calendar – joins the Collection Excellence Platine. This Haute Horlogerie classic is powered by the legendary Caliber 1120 SQP, an ultra-thin mechanical self-winding movement revealing the elegance and finesse of the Patrimony collection.


Caliber 1120 QP developed and crafted by Vacheron Constantin drives the hours and minutes hands, along with a perpetual calendar displaying the day of the week in a counter at 9 o’clock, the date in a counter at 3 o’clock, the month and leap year in 48-month counters at 12 o’clock and moon phases at 6 o’clock. Acknowledged by connoisseurs as one of the most iconic existing perpetual calendars, it will smoothly cope with all the vagaries of the calendar without requiring any corrections until March 1st 2100. Unlike simple calendars requiring manual correction after every month with less than 31 days, the perpetual calendar takes account of the leap-year cycle with its 31-, 30- and 28-day months, as well as the quadrennial recurrence of January 29th. This sophisticated function requires prodigious miniaturisation to mechanically adjust it so as to keep track of calendar irregularities. This miniaturisation has been taken to extremes in order to achieve an ultra-thin perpetual calendar. Vacheron Constantin Caliber 1120 QP measures just 4.05 mm thick, beats at the frequency of 2.75 Hz (19,800 vibrations per hour), and has a 40-hour power reserve. The oscillating weight cut out in the shape of a Maltese cross symbol further embeds the design codes of the Maison at the heart of the movement.


In keeping with the aesthetic codes of the Collection Excellence Platine born in 2006, this new Patrimony Perpetual Calendar is crafted in 950 platinum, as is the dial. The latter features a finely grained sand-blasted dial discreetly bearing the inscription “Pt50” between 4 and 5 o’clock, while the slightly convex external zone is adorned with a circular “pearl” minute-track and 18K white gold applied hour-markers. The hours and minutes hands are in 18K white gold, while the calendar pointers are in blued steel. Setting the finishing touch, the saddle-finish dark blue alligator strap is hand-stitched with silk and 950 platinum threads, and secured by a folding clasp in the same metal.
Revolving beneath the dial, the moon disc depicts the heavenly vault in white gold enhanced by a blue galvanic treatment. Each star has been delicately crafted so as to provide an exact map of the sky.
Fitted with a sapphire back enabling one to admire Caliber 1120 QP, the 41 mm-diameter case is water-resistant to 3 bar (approximately 30 metres).
This exceptional model will be launched in a strictly limited 100-piece edition.

White metal + White/silver dial + blue hands combo is already a winner in my book. On top of it all, it has one of the most beautiful automatic rotor.

I think this model is best represent VC in this year SIHH.
