A Patek Philippe Ref. 5013P platinum tonneau-shaped automatic minute repeater will lead Sotheby’s Hong Kong Important Watches Autumn Sale on October 5. The circa 2004 watch with a perpetual calendar, retrograde date, moon phase and leap year indication has an estimate of $359,000 – $487,000.
Launched in 1992, the Reference 5013 is one of the most complex timepieces ever made by Patek Philippe, with a total of 515 parts, Sotheby’s said. It is also the first minute-repeater to feature an automatic movement combined with a perpetual calendar and retrograde date indication. The retrograde date hand moves along a 270 degree arc and flies back to the first of the month at midnight of the last day of each month.
The sale at the Hong Kong Convention and Exhibition Centre will present rare and complicated timepieces from celebrated makers, as well as other cutting-edge modern wristwatches by both established and independent brands. The sale will showcase more than 290 lots and has an estimate of $4.7 million – $6.85 million.
Other auction highlights include the following:
* A Patek Philippe, Ref. 5101G-001, circa 2011. The white gold rectangular tourbillon watch with a 10-day power reserve has a triple-stepped case inspired by Patek Philippe’s Art Deco designs. The tourbillon rests on the bridge side as the dominant element of the movement revealed through the sapphire crystal case back. The rotating cage is composed of 72 individual parts, yet weighs only 0.3 grams. It takes a Patek Philippe watchmaker up to three months to produce a Ref. 5101. It is one of only two examples of a Ref. 5101 in white gold to be offered at auction. Its estimate is $103,000 – $154,000.
* A Richard Mille RM025 carbon composite and titanium skeletonized tourbillon chronograph diver’s watch with power reserve and torque indication. The circa 2014 timepiece is water resistant to 300 meters. The RM025 caliber unites the complication of a tourbillon with the chronograph movement. The torque indicator, which shows the tension of the mainspring, ensuring the chronometer function of the movement, is positioned to the right of the barrel, between 12 and 1 o’clock. Its estimate is $154,000 – $206,000.
* An A. Lange & Söhne, platinum rectangular tourbillon watch with patented stop-seconds mechanism, date and power reserve indication, cabaret tourbillon, circa 2011. Its estimate is $103,000 – $154,000.
* A single-owner collection of sport watches “characterized by their youthfulness and masculine charm, encompassing limited editions by prestigious makers such as Audemars Piguet, Panerai and Jaeger-LeCoultre,” Sotheby’s said.
* An Audemars Piguet Royal Oak Offshore chronograph with pink gold and forged carbon tourbillon, case H03575, circa 2010. This piece features an openworked dial revealing twin barrels, offering a 10-day power reserve with the column wheel chronograph mechanism and tourbillon fully visible. Its estimate is $103,000 – $154,000.
