DESCRIPTION
Unquestionably one of Patek Philippe's most recognizable grand complications is the reference 3940; an emblematic perpetual calendar that stands out for its timeless beauty. When it was introduced in 1984, it was the slimmest automatic perpetual calendar wristwatch and replaced the reference 3450.
Feel free to ask any further information.
