In 1985 the International Watch Company introduced the automatic chronograph "Da Vinci" with perpetual calendar and moon phase display. It is fitted with a highly intricate mechanism that digitally displays – in addition to the usual chronograph 30 minute and 12 hour counter – the day of the week, the date, the months and the year until 2499. These indications can be advanced synchronously in a single step. Reference 3752 also features a minute tourbillon – another much coveted complication in any superior watch.
