| Patek Philippe Ref 5001T Sky Moon Tourbillon |
A unique collection of watches that includes five bespoke Patek Philippe references made in titanium will be part of Sotheby’s New York Important Watches auction on June 10. The collection of vintage and modern timepieces is led by the Patek Philippe Ref 5001T Sky Moon Tourbillon, a previously undocumented reference and the only known example of Patek Philippe’s Sky Moon Tourbillon in titanium. Its estimate is $1 - $1.5 million.
The double dialed wristwatch has 12 complications including tourbillon, perpetual calendar, retrograde date, sky chart, moon-phases, orbit display, sidereal time and minute repeating on cathedral gongs, made circa 2002. In addition to the lightweight metal, the watch is further distinguished by its basket weave motif, repeated on the bezel and the dial where the standard Sky Moon Tourbillon normally features the firm’s signature Calatrava crosses, as well as unabbreviated cardinal points on the star chart.
The Patek Philippe titanium timepieces are part of a private collection of 12 watches that includes additional references by Patek Philippe that have remained unknown to collectors, as well as unique pieces incorporating rare materials and designs beyond titanium. The timepieces have a total estimate of more than $3 million.

| Patek Philippe Ref 5033T, titanium automatic annual calendar minute repeating wristwatch. |
In addition to the Ref 5001T, highlights of the previously unknown titanium wristwatches by Patek Philippe include: the Ref 5033T, a titanium automatic annual calendar minute repeating wristwatch made in 2003 (estimate est. $400,000 - $600,000); and the Ref 5102T Celestial, a titanium automatic astronomical wristwatch with sky chart, phases and position of the moon and time of Meridian passage of Sirius and the moon, made in 2003 (estimate. $200 $300,000).
Until this auction, there were only four known watches in titanium made by Patek Philippe.
“When first learning about this collection, it was almost impossible to conceive of so many important yet unknown pieces from Patek Philippe,” Daryn Schnipper, chairman of Sotheby’s Watch & Clock Department, said in a statement. “The five titanium watches are an absolute revelation. This group is a testament to the influence and ultimate connoisseurship of its collector, who had the foresight to customize these references in discreet yet significant ways.”

Another star of the private collection is the Patek Philippe 1923 Officier, which Sotheby’s said is one of the most important wristwatches produced by the firm. The yellow gold single button split-seconds chronograph originally sold on October 13, 1923, making it the earliest known split-seconds chronograph produced by the firm. It is the only split-seconds chronograph by Patek Philippe to feature a white enamel dial. Its estimate is $800,000 - $1.2 million.
