Rose gold and blue-lacquered offer a perfect combination of casual chic. For the first time, Vacheron Constantin is offering this pleasing association of colors by presenting a new Overseas Perpetual Calendar with a gold case and bracelet along with a blue dial. A spirited combination that endows this model with a distinctive new personality.
The Overseas Perpetual Calendar Ultra-Thin watch is now treating itself to an all-gold version. Its precious metal bracelet, featuring links inspired by the shape of the Maltese cross, is more elegant than ever while radiating a style all its own.
In addition to the case/bracelet combination, the brilliance of the gold extends to the blue dial, whose hour-markers, hands and moon discs are also made of rose gold. While the blue-lacquered gold dial captivates the eye with its sunburst satin finish, the counters are distinguished by their snailed decoration, while the gold-rimmed minute-rack opts for a velvet finish. These delicate decorations contrasting with the vertical-brushed of the case endow the blue dial with its full strength of character.
The 41.5mm-diameter case accommodates a mechanical self-winding movement from a proud lineage, the ultra-thin manufacture 1120 QP/1 caliber with perpetual calendar and moon-phase display. The latter function involves impressive feats of miniaturization enabling it to cope with calendar irregularities while eliminating any need for correction until 2100. No less than 276 components are housed in a thickness of barely 4.05mm. Beating at a frequency of 19,800 vibrations per hour and endowed with an approximately 40-hour power reserve, the mechanism drives indications of the hours, minutes, perpetual calendar function – with the day of the week, date, month and leap year shown on a 48-month counter – as well as moon phases.
