Elegant And Chic: Vacheron Constantin 2011 Perpetual Calendar Watch

In 2011, Vacheron Constantin’s iconic Patrimony Contemporaine heritage series is about to usher in a highly anticipated complication watch: the perpetual calendar watch. The Patrimony Contemporaine ultra-thin perpetual calendar watch uses the classic legend, the 1120 QP self-winding mechanical movement with the prestigious Geneva mark, representing Vacheron Constantin’s timeless elegance and refinement.

Minjiang Stanton Patrimony Contemporaine series adds a high-performance watch with excellent functions and sophisticated design. The 1120 QP movement, which is highly regarded by watch connoisseurs, is regarded as one of the classic perpetual calendar movements. Ren Guangyin, Star Wars, this perpetual calendar watch can control the flow of time, no need to adjust the date before March 1, 2100.
Different from the ordinary calendar display, the watch needs to be adjusted in months with less than 31 days, and the perpetual calendar function takes into account the leap year cycle and the number of days in the month (divided into 31 days, 30 days, and 28 days). The 28 days of the month are adjusted to 29 days. The mechanism needs to be adjusted automatically according to irregular changes in the number of days in the month, highlighting the extraordinary skills of micro-production. The thickness of the Vacheron Constantin 1120 QP ultra-thin perpetual calendar movement is only 4.05 millimeters. Creating such a movement has extremely strict requirements for micro-manufacturing processes.
Equipped with the hand-wound calibre 1120 QP engraved with the Geneva Seal, the well-polished balance wheel is the hallmark of fine watchmaking. The vibration frequency of the movement is 2.75 Hz (19,800 vibrations per hour), and the power reserve is about 40 hours. The movement can display the hour, minute and perpetual calendar, the sub dial at 9 o’clock, the sub dial at 3 o’clock, the sub dial at 48 o’clock at 12 o’clock, the month and leap year, and the moon phase profit and loss at 6 o’clock.
The extreme fine craftsmanship of the new Perpetual Calendar watch by Minjiang Shidanton is astounding. Following the characteristics of the Patrimony Contemporaine series, simple lines, sleek outlines, slim trapezoidal hour markers, bar pointers, micro-arch curved dial design and minute markers set with convex gold beads. Under the milky silver-plated dial, the crescent-shaped moon phase profit and loss shows that the disk looks like a golden bright moon in the dark blue night sky. The case is made of 18K pink gold, with a diameter of 41 mm and a water resistance of 30 meters. The 1120 QP movement is clearly visible through the sapphire crystal case back. The Patrimony Contemporaine perpetual calendar watch comes with a crocodile leather strap and 18K pink gold folding clasp.
On the basis of this work, Vacheron Constantin also created Patrimony Traditionnelle perforated watch with the same function, exquisite and unique, perfectly interpreting the classic temperament of the watch in an elegant and novel way, showing the 250 years of outstanding quality First-class technology.
