Vacheron Constantin Perpetual Calendar, 43031


First launched in 1983, the Vacheron Constantin ref. 43031 was one of the pieces which helped renew the interest in complicated watchmaking, following the decimation caused by the Quartz Crisis. Alongside similar pieces from Audemars Piguet and Patek Philippe, it is one of the few ultra-thin, automatic perpetual calendars introduced during this period.
