Episode 81: The Patek Philippe ‘Pure’ Perpetual Calendar (Beginnings until 3940)

A monumental occasion, this episode covers a complete chronology of the Patek Philippe ‘pure’ perpetual calendar. Arguably, the QP was the complication that built the Patek Philippe name more than any other through the mid-century. Yet, the main bloodline of QP has many nuances that aren’t often covered. This episode highlights all the main references you might expect and their significant points such as 1526, 2497/2438, 3448, and 3450. But if you’ve ever wondered about the 96 QP, 1527, 1591, 3449, or any of the oddball piece uniques, they’re all in here too. We couldn’t wait for leap year to release this, hopefully you’ll forgive us. 3940 and on will be in an upcoming part two.
