Editor's Notes

Distinguished Swiss horologist Vacheron Constantin was founded in 1755 and many of the watches it crafts today are inspired by models from the house's archives. This ultra-thin 'Patrimony' style has an 18-karat pink gold case sculpted into a perfectly round shape just like those classic designs from the '50s. It's powered by the house's calibre 1120 QP automatic movement that drives the minute and hour hands and perpetual calendar, too – the 276 internal parts are able to follow leap years. The visually arresting moon phase indicator is positioned just above the 6 o'clock mark and showcases lunar movements.
