1933 Supercomplication
2014 SOLD for CHF 23.2M by Sotheby's
Patek Philippe knew to listen to their wealthy private clients. The Geneva brand remains for that reason since over a century the pioneer of miniaturization accompanied by an increasing number of complications in pocket watches and later in wristwatches.
By 1900, the Palmer specimen was a pocket watch with minute repeater, months, days of the week, split-second chronograph, grande and petite sonnerie and the phases of the moon.
James Ward Packard, the car industrialist, was one of the most demanding customers of Patek Philippe. In 1916, he obtained a pocket watch with sixteen complications, and in 1927 he had a celestial chart added to nine other complications in a single watch.
When Packard died in 1928, the New York banker Henry Graves Jr. had already ordered the world's most complicated pocket watch, with 24 complications divided into two dials including the night time sky from New York City.
Completed in 1932, the Supercomplication is a unique piece for which Patek Philippe had mobilized their best specialists. The assembly of its 920 components in a case 74 mm in diameter and 36 mm thick is a technical feat that will remain unmatched until the era of computer-aided design.
The Supercomplication was delivered to Graves on 19 January 1933 for CHF 60K, nearly five times the price of the ultimate Packard watch. It was sold by Sotheby's for $ 11M on December 2, 1999 and for CHF 23.2M on November 11, 2014, lot 345. Please watch the video shared by the auction house.

Reference 1518
Intro
During the 1930s Patek Philippe masters all the complications and most of their combinations. The brand's effort to make new prototypes and to add new high-end references to its catalog is not interrupted by the war.
The reference 130, launched commercially in 1934, is a single-push chronograph using the calibre 13. It is equipped with two subsidiary dials, one indicating the seconds up to the minute and the other the minutes up to the half hour. Produced from 1940, the reference 1491 is a watch without chronograph with a more elegant design than the already classic Calatrava.
In production from 1941 to 1954, the reference 1518 is the first commercial wristwatch from any brand to offer altogether these two appealing complications which are the chronograph and the perpetual calendar, in addition to the moon phases.
281 watches are built in this reference which is an average of 20 per year. The list of customers includes the kings of Egypt, Jordan and Romania and the boxing champion Sugar Ray Robinson, and also the all time top collector Henry Graves Jr.
Most 1518s are in yellow gold, plus an estimated 58 in pink gold.

1943 Stainless Steel
2025 SOLD for CHF 14.2M by Phillips
Until the second world war and a little beyond, the use of stainless steel is exceptional in the high-end wristwatches made by Patek Philippe. Owners identify luxury with gold or platinum. Steel watches are produced on special request from customers who fear some wearing related to their own heavy use.
The 1518 in stainless steel is extremely rare : only four units are known. This rarity is logical : we must indeed recognize some contradiction between the need for a perpetual calendar and the fear of wear.
The first two 1518s in stainless steel were manufactured in 1943 and sold together in February 1944 to a Hungarian retailer who also imported later the No. 3. Their case was made by Croisier later known as Genevor and the dial by Stern Frères.
The No. 1 remaining in an immaculate condition had probably been intended as a spare by its unidentified first owner. It was sold by Phillips for CHF 11M on November 12, 2016, lot 38 and for CHF 14.2M on November 8, 2025, lot 23. The 2025 video is shared by the auction house and narrated by Aurel Bacs.

Breaking News Stainless Steel Patek Philippe Ref. 1518 Sells For Over $11,000,000 At Phillips Geneva http://bit.ly/2eSH6tN
additional information by Grok in an invited query from the above thought :
There are four known stainless steel examples of the Patek Philippe Reference 1518 perpetual calendar chronograph, out of 281 total examples produced across all metals from 1941 to the mid-1950s. All four were manufactured in 1943–1944 during World War II, measure 35mm in diameter, and feature manually wound movements based on a modified Valjoux ébauche finished by Patek Philippe. Three share sequential Genevor SA cases (numbers 508473, 508474, and 508475) with pierced lugs and are marked "1," "2," or "3" inside the casebacks, indicating their production order; these were originally sold to Hungarian retailer Joseph Lang in Budapest. The fourth has a distinct Wenger case (number 6335561) with wider, solid lugs. All have been handled at least once by prominent dealer Davide Parmegiani, and none are housed in the Patek Philippe Museum—contrary to some rumors—as they remain in private collections.

1948 Pink on Pink
2021 SOLD for $ 9.6M by Sotheby's
An immaculate one-owner Patek Philippe wristwatch reference 1518 was sold for $ 9.6M from a lower estimate of $ 1.2M by Sotheby's on December 9, 2021, lot 55.
This watch made in 1948 was sold in 1951 to a first cousin of King Farouk. Previously unknown, it was discovered as a completely original time capsule in a safety deposit box after the recent death of the prince. It is still accompanied by its presentation case, certificate of origin and operating instructions to adjust the calendar.
This 1518 is in the very rare pink on pink configuration, specially designed for a warm tone effect associating a pink dial to the 18k pink gold of the case. 13 other examples are known. Most of the other pink gold 1518s have a silvered dial.

Reference 2523
Intro
Patek Philippe began in 1937 to assemble World Time watches (Heures Universelles, HU) with the movement patented and supplied by Louis Cottier, without obtaining an exclusivity. A ring marked from 0 to 23 rotates counter clockwise in synchronisation with the hands. Another ring identifies about 40 cities or places. The time everywhere around the world is read directly by the position of these inscriptions in front of the rotating ring.
After the ephemeral 96 HU and 515 HU references used by Patek Philippe in the development phase, the reference 1415 HU released in 1939 marks a stabilization of that offer. 115 pieces were made. A 1415 made in 1949 with the Eurasia cloisonné enamel dial (HU DE subvariant) was sold for CHF 970K by Phillips on May 13, 2018, lot 268.
In 1953 the reference 2523 replaces the 1415 after a modification of the Cottier calibre associated with a dual crown enabling to change the reference setting of the time zone. The 2523 is a luxury watch, most often equipped with an enamelled dial. The case embedding the double crown is a technical feat. Two batches were produced in two ranges of movement numbers for a possible high total of 5 + 20 watches or slightly more.
Only four 2523 are known from the first 1953 batch of movements. Three are fitted with an Eurasia cloisonné enamel dial and the fourth is a guilloché. The Eurasia design is a reuse from one of the dials of the 1415 in flat colors. The graduation of the enamel colors of the 2523 is arguably unprecedented.
The second 1953 batch was fitted with North America, South America, enamel blue and guilloché dials, with no Eurasia added.
The 2523 is in turn replaced in 1957 by its variant 2523-1 with a simplification of the lugs and a metal dial. The production of HU movements ceases in 1965.

1953 Eurasia in Yellow Gold
2024 SOLD for HK$ 65M by Christie's
Three 2523 from the first 1953 batch of movements are fitted with an Eurasia cloisonné enamel dial. The Eurasia design is a reuse from one of the dials of the 1415 in flat colors. The graduation of the enamel colors of the 2523 is arguably unprecedented.
The second 1953 batch was fitted with North America, South America, enamel blue and guilloché dials, with no Eurasia added.

1953-1954 Ocean Blue in Pink Gold
2019 SOLD for HK$ 70M by Christie's
A pink gold 2523 in excellent condition without any sign of repair surfaced in 2010. It was twice sold by Christie's, for CHF 2.7M on November 15, 2010, lot 114, and for HK$ 70M on November 23, 2019, lot 2201. Please watch the video prepared by the auction house.
The dial and movement were made in 1953 and the case in 1954. The centre of its dial is not in cloisonné but is monochrome in a beautifully translucent ocean blue enamel. The watch was sold to Gobbi in Milan in 1957. It is the only 2523 to have on its dial a double signature of Patek Philippe and a retailer, a feature that is today eagerly sought after by watch collectors. The movement is from the second 2523 batch.

2006 full set of four Calibre 2000 by Patek Philippe
2025 SOLD for $ 12M by Sotheby's
A full original set of four high complication Patek Philippe Calibre 2000 pocket watches assembled ca 2006 was sold for $ 12M by Sotheby's on December 5, 2025, lot 342.
Another single watch had been narrated by ArtHitParade as follows :
The Calibre 89 with its 33 complications was made in 4 units in 1989. It is a marvel of miniaturization, but not enough to be worn on the wrist : it weighs 1,100 grams and its 1,728 components are positioned in a case of 89 mm in diameter and 41 mm thick.
For entering the new millennium, the Swiss brand is 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 in 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 find 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 18k gold Star Calibre 2000 assembled ca 2008 was sold for HK $ 25M by Christie's on November 28, 2012, lot 2952.

Overview of the Star Caliber 2000
The Patek Philippe Star Caliber 2000 (also spelled Star Calibre 2000) is a double-sided pocket watch unveiled in 2000 to commemorate the new millennium. Measuring 73.22 mm in diameter and weighing over half a kilogram, it represents a pinnacle of haute horlogerie, blending astronomical, calendar, and chiming functions in a single, user-friendly mechanism. Developed over seven years (conceived in 1993 and completed in October 2000) under the direction of then-president Philippe Stern, it involved dozens of artisans and external specialists, including case maker Jean-Pierre Hagmann and engraver Christian Thibert. Its cases, in bassine style with Renaissance-inspired engravings, were produced in yellow gold, rose gold, white gold, and platinum.

Significance of the Sotheby's Lot 342 Offering
This "never used" full set—presumably one of the four mixed-metal sets, in pristine condition with original box, documents, and accessories—marks a historic debut: The first complete set ever to appear at public auction. Offered as Lot 342 on December 5, 2025, during Sotheby's inaugural Abu Dhabi Collectors’ Week (in collaboration with the Abu Dhabi Investment Office), it carries an estimate in excess of $10 million—the second-highest for any watch (behind only the Graves' $24 million in 2014). This could shatter records for Patek pocket watches and highlight the Middle East's emerging role in luxury collecting.
The lot's untouched state amplifies its allure: It offers not just rarity but completeness, allowing a collector to own the full spectrum of metals and engravings. As Sotheby's Global Chairman of Watches Sam Hines notes, it's a "once-in-a-generation" opportunity, potentially drawing institutional bids. This sale elevates the Star Caliber from legend to tangible icon, ensuring its legacy endures beyond private vaults. For Patek enthusiasts, it reaffirms the model's transformative importance—a mechanical symphony that, 25 years on, still outshines most contemporaries in ingenuity and grace.

Technical Specifications and Innovations
At its core, the Star Caliber 2000 features:
- 21 complications, including:
- Perpetual calendar with leap year cycle and rapid correction (advances up to one month at a time).
- Westminster chimes (Grande Sonnerie on passing and minute repeater on demand), the first faithful mechanical reproduction of Big Ben's sequence, achieved via a patented dual-tone striking mechanism.
- Astronomical displays: Sky chart, lunar orbit, moon phases, time of meridian passage by Sirius and the Moon, sunrise/sunset times (controlled by the perpetual calendar), and running equation of time (via a central star-tipped hand).
- Power reserve indicators for the movement (72 hours) and chime.
- 24-hour display and constant seconds with seasons.
- 1,118 hand-finished components, making it one of the most intricate movements Patek has produced.
- Six patented inventions, such as the selective opening cover, rapid calendar corrector, and perpetual calendar integration for astronomical functions.
Rarity and Production Details
Patek produced only 20 examples, organized into five complete sets:
- Four sets: One watch each in yellow gold, rose gold, white gold, and platinum.
- One set: All four in platinum, with unique engravings.
This extreme scarcity underscores its status as a "phantom" masterpiece—little-seen, even by experts, until now.
Historical Importance in Patek Philippe's Legacy
The Star Caliber 2000 holds a pivotal place in Patek Philippe's 185-year history as a bridge between the brand's storied tradition of supercomplications and modern horological philosophy:
- Ranked Among the Elite: Upon release, it was the fourth most complicated watch ever (behind Patek's Caliber 89, the 1904 L. Leroy 01, and the 1933 Henry Graves Supercomplication). Within Patek's oeuvre, it ranks third in complexity, affirming the brand's unchallenged dominance in mechanical innovation. It succeeded the Caliber 89 (Patek's 150th-anniversary tribute) and echoed the Graves' bespoke grandeur, but with a forward-looking emphasis on "practical poetry"—focusing on life's rhythms (time, stars, seasons) rather than exhaustive complication counts.
- Millennial Milestone: Conceived amid Y2K anticipation, it symbolized Patek's transition into the 21st century, much like the Caliber 89 did for the late 20th. It demonstrated the manufacture's ability to evolve: While predecessors like the Graves took six years for one client, the Star Caliber was a collaborative triumph, involving team watchmaking (one artisan alone would have needed 18 years). This foreshadowed Patek's later advances, such as silicon-based components (e.g., Spiromax balance spring in 2006) and wristwatch supercomplications like the Sky Moon Tourbillon (Ref. 5002).
- Innovation and Philosophy: Beyond mechanics, it embodies Patek's ethos: Preserving traditions (e.g., hand-engraving, Westminster chimes) while pioneering user-centric designs. The patented chime mechanism, for instance, resolved longstanding acoustic challenges, influencing subsequent minute repeaters. Its astronomical focus—sky chart, Sirius transit—evokes Patek's 19th-century celestial watches, while the rapid corrector addressed modern disuse. Patek even published a dedicated book (with DVD and 3D animations) to demystify its "enchanting world," educating collectors on this fusion of art and science.
- Cultural and Market Impact: Rarely discussed even among connoisseurs due to its privacy, the model has "changed the history of watchmaking" by elevating pocket watches as sculptural art in an era of wristwatches. Its 2000 debut coincided with watch collecting's rise (Sotheby's watch sales grew from $26.8 million that year to $158.3 million by 2024), positioning Patek as the aspirational apex.

This could shatter records for Patek pocket watches and highlight the Middle East's emerging role in luxury collecting.
The lot's untouched state amplifies its allure: It offers not just rarity but completeness, allowing a collector to own the full spectrum of metals and engravings. As Sotheby's Global Chairman of Watches Sam Hines notes, it's a "once-in-a-generation" opportunity, potentially drawing institutional bids. This sale elevates the Star Caliber from legend to tangible icon, ensuring its legacy endures beyond private vaults. For Patek enthusiasts, it reaffirms the model's transformative importance—a mechanical symphony that, 25 years on, still outshines most contemporaries in ingenuity and grace.

2019 6300A-010
2019 SOLD for CHF 31M
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 was 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 that year Patek Philippe supplied the unique copy of Grandmaster Chime in stainless steel, reference 6300A-010, lot 28. The steel improves the sound. It is inscribed "The Only One" on one of the dials. It was sold for CHF 31M.
The lot included a one-day private tour of the workshops and museum for two people and a lunch with Thierry Stern, president of Patek Philippe.
