Vacheron Constantin Overseas Ultra-thin Perpetual Calendar – Calibre 1120 QP
The Overseas Ultra-thin Perpetual Calendar bearing the Hallmark of Geneva certification and available exclusively at Vacheron Constantin boutiques houses the Vacheron Constantin Calibre 1120 QP, an ultra-thin mechanical automatic movement equipped with a perpetual calendar complete with moon phases. This function calls for impressive feats of miniaturisation in order to adjust to calendar irregularities while requiring no adjustment until the year 2100, as well as to accommodate its 276 components within a space barely 4.05 mm thick. Beating at a frequency of 19,800 vibrations per hour and endowed with an approximately 40-hour power reserve, the mechanism drives the hours, minutes and perpetual calendar – with day of the week, date, month and 48-month leap-year indications – as well as the moon phases.
The 18 carat white gold 41.5-mm-diameter case frames a grey dial lightly punctuated by blue accents, while the sapphire crystal caseback reveals a 22 carat oscillating weight adorned with a compass rose and subtle finishes. This new reference radiating a pleasing appearance in every situation is fitted with an interchangeable white gold bracelet complete with an easy-fit system and complemented by two leather and rubber variations, both secured by a white gold buckle
