2008 Patek Philippe greets the New Millennium
2012 SOLD 25 MHK$ including premium
The progress of contemporary watchmaking is going prepared in secret in the laboratories of Patek Philippe.
The Calibre 89 is well known in this group. This watch offering 33 complications was made in 4 copies in 1989. It is a marvel of miniaturization, but not enough to be worn on the wrist: it weighs 1100 grams and its 1728 components are positioned in a case of 89 mm in diameter and 41 mm thick. The yellow gold Calibre 89 was sold CHF 5.1 million including premium by Antiquorum on November 14, 2009.
Nothing stops the development effort of Patek Philippe. For approaching a new millennium: the Swiss brand was preparing a new feat. In 2008, the Star Calibre 2000 is ready.
The Star Calibre 2000 is smaller than the Calibre 89 with "only" 73 mm diameter, 32 mm thick and 530 grams, but it includes 21 complications, some of which show a really renewed imagination.
Perpetual calendar, equation of time, minute repeater are classical complications. We also appreciate in this model the time of crossing the meridian by the Moon and Sirius, the sky chart and the ring that mimics the Westminster chimes. It is protected by six patents, one of which for the time of sunrise and sunset.
A Star Calibre 2000 is estimated HK $ 18M, for sale by Christie's in Hong Kong on November 28. This is one of the three Patek Philippe watches from the Dragon collection highlighted in the video shared by Christie's.

2008 The Time of Earth and Sky
2013 SOLD 1.2 MCHF including premium
The technical feat of contemporary watchmaking is the Star Caliber 2000, a pocket watch announced by Patek Philippe in October 2000. Its complications have been specially selected for their difficult compatibilities.
In March 2001, Patek Philippe launched the most complicated wristwatch, the 5002 Sky Moon Tourbillon, taking advantage of technologies developed for the Star Caliber 2000. In the 5002, 686 components activate 12 complications in a case of 45 mm in diameter and 18 mm high. The price announced in 2001 was CHF 950K in yellow gold and CHF 990K in platinum.
Another innovation for Patek Philippe in the 5002 is the presence of two dials. The front dial is classic, but the dial below has a mobile sky map of the Northern Hemisphere including among other indications the sidereal time, the phases of the Moon and the passages of Sirius.
The extreme complexity for the assembly of the 5002 limited its production to two pieces per year. A platinum 5002P was sold HK$ 11.7 million including premium by Sotheby's on 10 April 2008.
On May 12 in Geneva, Antiquorum sells an exceptional specimen of 5002, released in 2008 on a special order. This very rare example in pink gold, presented in its original box with its documentation, is estimated CHF 1M, a price that may be considered as reasonable now that the model has been discontinued.
Both sides are shown in the article shared by The Watch Lounge.

2010 The Sky on the Wrist
2016 SOLD for CHF 1.15M including premium
The dream of men to calculate the configuration of the sky with a handheld tool had been achieved for many centuries : it was the astrolabe. Since the late 1980s Patek Philippe offers increasingly subtle complications to the lovers of the astronomical time.
The most complicated watch of all time is their Calibre 89 with 33 complications. With 22 complications, the Star Caliber 2000 is like the Calibre 89 a pocket watch, but its development paved the way for the most complicated wristwatch, the Sky Moon Tourbillon 5002 produced from 2001 to 2011.
Astronomers may be delighted : with the 5002 they control time and sky on their wrist with no less than 12 complications among which the most recent innovations include the sidereal time, the retrograde calculation of the perpetual calendar and the meridian of Sirius selected because it is the brightest star.
To avoid a too tight display the 5002 is the first wristwatch with double dial made by Patek Philippe. The progress is not just about astronomy : the new cathedral chime, prolonged and more musical, appeals its wealthy owners.
The assembly of the 686 tiny mechanical components of the 5002 is of high complexity. Its average production was around 10 units per year. The 6002 reference launched in 2013 is a deluxe dressing for the 5002.
The platinum version of the 5002 is referenced 5002P. One of them was sold for HK $ 11.7 million including premium by Sotheby's on April 10, 2008. Another 5002P manufactured in 2010 is estimated CHF 950K for sale by Christie's in Geneva on November 14, lot 146.

2011 Patek Philippe for OnlyWatch
2011 SOLD 1.4 M€ with no applicable buyer's premium
Held every two years since 2005 in Monaco, the OnlyWatch event has become an unavoidable showcase for contemporary Swiss watches.
The principle, which is to have submitted by each manufacturer a unique model at auction, is necessarily pleasing Patek Philippe. For nearly a century, the models made as a single specimen were used as benchmarks for the technological developments and the design changes of the brand.
In 2007, the contribution of Patek Philippe to OnlyWatch was a unique 5712T Nautilus in titanium, sold € 525K.
On September 23, in the sale conducted by Antiquorum, Patek Philippe offers a unique watch based on the model 3939. Organizers hope between € 450K and 650K. This smart tourbillon watch with a beautiful black enamel dial is illustrated in the article shared by WatchTime.
This sale is for glory in the best meaning of that term, since all the proceeds are going to benefit a charity against Duchenne muscular dystrophy.
Richard Mille's contribution to OnlyWatch 2011 has also been featured in this group.

2012 A Skeleton under the Sapphire
2017 SOLD for $ 1.2M including premium
The Richard Mille company offers wristwatches of very high performance, often associating with its models the sponsorship of a sports champion. Advanced technologies bring weightlessness, transparency and robustness against severe environment.
The release in 2012 of the RM 056 - Felipe Massa in a limited edition of five was an event in terms of watchmaking innovation. Its price was about $ 1.7M. The three pieces that make up the case of this split-seconds chronograph watch are transparent with an absolute clarity, allowing the user to see from any angle the movement of the tourbillon.
The transparent material is a sapphire crystal, resistant to any scratch. The machining and polishing of a sapphire piece takes several hundred hours. The use of titanium is extended to all mechanical components and to the baseplate. The case is water resistant to 50 meters.
Evolution has already gone forward. The RM 56-01 has its baseplate and its third hand in sapphire. RM 27-01 - Rafael Nadal and RM 56-02 incorporate a further improvement in the suspension of the movement on the baseplate. At its release in 2014 the price of the RM 56-02 was about $ 2M.
On June 21 in New York, Christie's sells the prototype No. 2 of the RM 056, lot 228 estimated $ 1M. The number of prototypes realized for that model has not been disclosed.

Organized every two years by the Association Monégasque contre les Myopathies, the OnlyWatch charity sale requires the offer by each participating brand of a watch guaranteed as unique of its kind. The 2017 event is entrusted to Christie's in Geneva on November 11.
Patek Philippe responds most often with a high-end model in a refractory metal unusual in its similar productions : titanium in 2007 and 2013, steel in 2011 and 2015. The Patek Philippe 5016A-010 sold by Phillips on November 7, 2015 fetched CHF 7.3M.
The titanium comes again in 2017 with the unique Patek Philippe 5208T-010, lot 12 estimated CHF 900K.

2018 Sympathique with the Rubidium
2019 SOLD for $ 2.9M including premium
The advancement of timekeepers includes the complications, of course, but also the search for the best accuracy. In the last century, for George Daniels, Abraham-Louis Breguet remained the absolute reference for mechanical watchmaking. Urwerk, a Swiss brand created in 1997, takes over.
One of Breguet's most avant-garde designs was the Breguet Sympathique, a pocket watch that did not need to be touched for winding, time setting and regulation. When its power reserve approached depletion, it was inserted into a clock to which it was mechanically coupled. The word Sympathique is an evocation of the coupling, by its etymology meaning 'functioning by affinity'.
Obtaining the three settings simultaneously was a mechanical feat that was achieved by his workshop for the duc d'Orléans in 1835, twelve years after Breguet's death. Restarted to working condition by Daniels in the 1970s, the complete system was sold for $ 6.8M including premium by Sotheby's on December 4, 2012.
The Urwerk AMC (Atomic Mechanical Control) system unveiled in 2018 at Baselworld Miami is an adaptation of the Sympathique to the modern technologies. Without a direct application identified, this technical feat paves the way for new developments.
The time reference is provided by a 45 x 30 x 18 cm atomic clock weighing 35 Kg. It uses the quantum energy transitions of the rubidium atom, known by physicists to provide the best stability with a 1 second error for 317 years when it is associated with a garnet of yttrium and iron. It provides the stability of a wristwatch by coupling, without manual winding, without quartz, without battery.
Urwerk announced the production of the system in three units. A price of $ 2.7M was announced in period on the web by a specialized website. The titanium mechanical watch with the serial number 001 associated with its atomic clock is estimated to exceed $ 1M for sale by Phillips in New York on December 10, lot 8.

2019 Five Chimes on the Wrist
2019 SOLD for CHF 31M in charity sale without premium
In 2014, for celebrating the 175th anniversary of the brand, Patek Philippe release their first Grandmaster Chime wristwatch under the reference 5175 edited in seven units. Its 20 functions required 1,366 components for the movement and 215 components for the case, surpassing the 6200 Sky Moon Tourbillon. It is the achievement of 60,000 hours of development over seven years.
The 5175 is 48 mm in diameter and 16 mm in height with 11 pushers and buttons. Its central mechanism activates in parallel the visual reading on two dials including the perpetual calendar, the chimes of hours, quarters, minutes and day, and the acoustic alarm preselected with an accuracy of a quarter of an hour. The running time of the mechanical winding is 72 hours in silent mode and 30 hours in grande sonnerie.
Two of these applications are unprecedented : the insertion of an alarm in a wristwatch, and the audible indication of the day in the month in two digits covering 1 to 31 by the tens and units. The watch also strikes on demand the current hour and minute. A security prevents the user from operating two mechanisms at the same time if they are not compatible.
The reference 6300G in gray gold launched in 2016 is similar to the 5175 except that the references to the celebration have been removed.
The Only Watch charity sale is held every second year since 2005 for the benefit of the research on the Duchenne muscular dystrophy. The 2019 auction is managed by Christie's in Geneva on November 9.
According to the rules applicable to this operation, each manufacturer offers a watch for which it guarantees that it is and will remain a one-off. On this year Patek Philippe supplies the unique copy of Grandmaster Chime in stainless steel, reference 6300A-010, lot 28 estimated CHF 2.5M. The steel improves the sound. It is inscribed "The Only One" on one of the dials.
The lot includes a one-day private tour of the workshops and museum for two people and a lunch with Thierry Stern, president of Patek Philippe.
