elegant replica watchVacheron Constantin welcomes a new perpetual calendar complication model to the Collection Excellence Platine.
Inside beats Caliber 1120 QP, an ultra-thin mechanical self-winding movement developed and crafted by Vacheron Constantin drives the hours and minutes hands, the moon phases at 6 o’clock 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. 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 February 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 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 case, as is the dial. The latter features a finely grained sandblasted dial discreetly bearing the inscription “Pt50” between 4 and 5 o’clock. 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 meters.
This exceptional model will be launched in a strictly limited and numbered 100-piece edition.
