Editor's Notes

Distinguished Swiss watchmaker Vacheron Constantin was founded in 1755 and has crafted high-end masterpieces non-stop ever since. This ultra-thin 'Patrimony' style is no exception, with an 18-karat pink gold case that recalls mid-century designs. It's powered by the house's calibre 1120 QP automatic movement that drives the minute and hour hands and perpetual calendar, too – the exact date will be kept until 2100 regardless of leap years. A gold-star-studded moon phase indicator is positioned just above the 6 o'clock mark.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing
