The annual calender is a unique function in that it accounts for the different lengths of months, The final day of June will be the 30th, and the final day of July and August will be the 31st. February is the only month that requires adjusting. Most watches bearing dates require adjustments every two months, and this watch only requires adjusting once a year. The Vacheron Constantin Calibre 2460 QRA has 326 parts functioning in precise harmony displaying the hours, minutes and small seconds at 9 o’clock, the annual calendar with retrograde date display, months as well as a conspicuous and exceptionally precise moon-phase indication which only requires correction once every 122 years.
Having a power reserve of 40 hours, a frequency of 28,800 vibrations per hours and crafted in ruthenium-plated 22K gold, the newest addition to the Quai de l’Ile collection, is a true testament to Vacheron Constantin continuing legacy. A legacy which began in 1755.
