Vacheron Constantin: Overseas Perpetual Calendar Ultra-Thin

Vacheron Constantin enriches the Overseas collection with a new ultra-thin model combined with one of the most fascinating complication… The perpetual Calendar.

Inside the ultra-thin case “41.5mm X 8,1 mm”, is enclosed the self-winding Vacheron Constantin 1120 QP calibre. Equipped with perpetual calendar and moon-phase functions this mechanism comprising 276 components housed within a space barely 4.05 mm thick copes with calendar irregularities and requires no related adjustments until the year 2100. Beating at the frequency of 2.75 Hz while enjoying a 40-hour power reserve, it drives indications of the hours and minutes, perpetual calendar – day of the week, date, month and leap year on a 48-hour counter – along with moon phases.

Water-resistant to 50 metres, the pink gold case frames a translucent silver-toned or blue lacquered dial punctuated by gold hands and hour-markers enhanced with luminescent material, while the sapphire crystal caseback reveals a 22K gold oscillating weight adorned with a wind rose. The blue-dial version is fitted with a blue leather or rubber strap (€. 78.000), while the version graced with a silver-toned dial flows into an 18K 5N pink gold bracelet (€. 96.000).
