This year Vacheron Constatin has proposed a series of models with undisputed charm, able to best summarize the maison's mastery - now in its 264th birthday - in terms of Haute Horlogerie and stylistic elegance.
The collection that best interprets these elements is certainly the Overseas Ultra-Thin Perpetual Calendar, which from SIHH 2019 has been enriched with two, new, further interpretations. A version, the one tested for you, embellished with a bewitching blue lacquered dial framed by the ultra-thin rose gold case mounted on a blue alligator strap; the second with translucent silver dial, enhanced by the perfect fusion of the case with the bracelet, also in pink gold.
The case in rose gold with a diameter of 41,5 mm is iWaterproof up to 50 meters. The blue dial is punctuated by rose gold indexes and hands with white luminescent material. Inside the ultra-thin case of the Overseas Ultra-Thin is enclosed the famous Caliber 1120QP / 1, often just move 4.04 mm, composed of 276 components. Equipped with a 40-hour power reserve, the caliber displays hour, minute, perpetual calendar indications - day of the week, date, month and leap year on a 48-hour counter - as well as moon phases.
The complication of "Perpetual calendar”Is one of the most complex and fascinating in watchmaking. Thanks to this complex movement, the watch is able to automatically take into account the irregularities of the months of the year, moon phases and solar years. For example, the movement will automatically advance from November 30th to December 1st without the need for manual intervention. The term "Perpetual" means precisely the peculiarity of intervening automatically, with the exception of the last year of the century. In this case, no adjustments will be required until the year 2100.
La 22-karat gold oscillating weight it is decorated with a compass rose, testifying to the adventurous nature of the Overseas collection.
The version with blue dial is equipped with a comfortable leather strap, easily interchangeable with the rubber one (supplied) thanks to the quick attachment / detachment system with the case. The clasp is of the deployant type with three blades, in rose gold, with buttons and extension system.
Available at a price of 78'000 Euros in the version with blue dial, alligator and rubber straps; 96'000 Euros for the version with silver dial and gold bracelet.
