Patek Philippe Grand Complication Only Watch

About this reference

The Patek Philippe reference 5016A-010 is a unique piece manufactured specifically for the 2015 Only Watch charity auction. While the standard production 5016 was available from 1993 to 2011, this specific iteration is the only example of the reference ever produced in stainless steel. It features the manual-wind caliber R TO 27 PS QR, which integrates a minute repeater, a tourbillon, and a perpetual calendar with a retrograde date hand and moon phase indicator. The watch is distinguished by a blue enamel dial and a 36.8mm case. Collectors value this reference for its combination of high complications within a steel housing, a metal typically reserved for the brand’s sports models rather than grand complications. In 2015, it sold for 7.3 million CHF. On the secondary market, its unique status places its valuation in the high-seven-figure range, though it has not publicly traded since its original auction.
