Catalogue Note:
Produced from 1994 to 2010, reference 5016 combines the three most exemplifying complications in watchmaking: the minute repeater, the perpetual calendar and the tourbillon. The reference is even further elevated with a moon phase and retrograde date. It was once the most complicated wristwatch ever produced by Patek Philippe, until suppressed by the Skymoon Tourbillon in 2001.

The retrograde perpetual calendar function is rarely deployed in Patek Philippe wristwatches, having only graced a handful of references in the modern era. The retrograde date has a fly back hand, and depending on the month and leap year cycle, the hand automatically jumps back to the first of the month after the 28th, 29th, 30th, or 31st. The fast flyback of the date hand is accomplished with a spiral spring and an ingenious rebound limiter mechanism developed and perfected by Patek Philippe. Further displaying Breguet numerals on the dial, the reference 5016 offers tranquility with its phenomenal presentation, with the perpetual calendar indications balanced in a perfect layout. Empowered by the mechanical caliber R TO 27 PS composed of 506 components, its tourbillon synchronizes in poetic fashion with the angelic chimes of the minute repeater. This masterpiece is accompanied with all its original accessories, and is in extremely well preserved condition.
