Vacheron Constantin caliber 1142 QP

Caliber 1142 QP, a state-of-the-art movement entirely designed and developed within the Manufacture, replaces the previous 1141 QP. The new movement drives the perpetual calendar functions – with indications of the date, days, months, leap years and moon phases – as well as the chronograph functions with a direct-drive seconds hands and 30-minute counter at 3 o’clock, positioned opposite the small seconds at 9 o’clock. Caliber 1142 will thus be able to keep track of all the vagaries of the calendar without any need for adjustments until March 1st 2100. Like all modern Vacheron Constantin movements, this caliber visible through an elegant transparent sapphire crystal caseback was developed and designed to meet the stringent Hallmark of Geneva criteria. This emblem of Geneva’s watchmaking excellence applies both to the caliber itself and to the finishing of the watch as a whole, governed by demanding norms that make it one of the most rigorous and renowned watch industry certifications.
