In 1989, Patek Philippe celebrated their 150th anniversary by launching one of the world’s most complicated wristwatch at the time, the reference 3974. This historical timepiece is the maison’s first serially produced automatic self-winding wristwatch with two of the most cherished complications amongst collectors, a minute repeater and a perpetual calendar housed into one. The only predecessors known are the ref. 541 made in 1939 and ref. 3621 in 1988, both one-of-a-kind pieces made specially for Mr. Philippe Stern himself.
