Unveiled in 2015 by Vacheron Constantin, the Reference 57260 pocket watch features an astonishing 57 distinct complications and took eight years to design and build. Among its most groundbreaking innovations is a fully mechanical Hebrew perpetual calendar, which required entirely new mathematical formulas to synchronize complex lunar and solar cycles. Weighing nearly a kilogram, this bespoke marvel stands as the most complicated mechanical watch ever created.

Patek Philippe is renowned for precious metals, but when a unique stainless steel Grandmaster Chime was forged for charity, it shattered expectations. Featuring
The Steel Patek That Shocked the Auction World
📅 Sunday, August 30, 2026
Patek Philippe is renowned for precious metals, but when a unique stainless steel Grandmaster Chime was forged for charity, it shattered expectations. Featuring 20 complications and a reversible case, this one-of-a-kind masterpiece fetched a staggering $31.19 million at a 2019 auction, making it the most expensive wristwatch ever sold.
Patek Philippe is synonymous with precious metals and traditional haute horlogerie, but in 2019 the manufacture created something deliberately extraordinary for the Only Watch charity auction: Grandmaster Chime Reference 6300A-010, the first and only version of the Grandmaster Chime produced in stainless steel. In a world where steel would normally be considered less intrinsically valuable than gold or platinum, its uniqueness made it considerably more tantalizing to collectors. Christie’s
And this wasn’t simply a special case wrapped around an ordinary watch. The Grandmaster Chime contains an astonishing 20 complications, making it Patek Philippe’s most complicated wristwatch. Among them are five acoustic functions: grande sonnerie, petite sonnerie, minute repeater, an alarm that actually strikes the programmed time, and a date repeater capable of acoustically sounding the date on demand. Patek identifies the alarm-with-time-strike and date repeater as patented world exclusives. Patek Philippe SA
Then there’s the case itself. The enormous 47.7 mm stainless-steel case uses a patented reversing mechanism, allowing the wearer to rotate the watch and display either of its two faces. One side features a rose-gold-colored dial with applied Breguet numerals; the calendar side is black ebony. Despite the steel exterior, Christie’s specifies that the actual dial plates are made from 18K solid gold. Christie’s
Patek made the Only Watch edition unmistakably unique in another wonderfully unsubtle way. On the alarm subdial appeared three words:
“THE ONLY ONE.”
And it really was. Reference 6300A-010 was created specifically for Only Watch 2019, with Christie’s describing it as the one and only stainless-steel Grandmaster Chime. Christie’s
Then came November 9, 2019, at Christie’s in Geneva. The bidding climbed through territory normally associated with historically important paintings rather than wristwatches. When it finally ended, the hammer had reached an extraordinary:
CHF 31,000,000
That was approximately US$31.1 million, and it established a new world auction record for any watch, not merely a wristwatch. The previous wristwatch auction record had belonged to Paul Newman’s Rolex Daytona, while the famous Patek Philippe Henry Graves Supercomplication had held the broader watch record. The steel Grandmaster Chime surpassed them both. Christie’s
And there’s another reason the result mattered: Only Watch is a charity auction. The event was established to raise funds for research into Duchenne muscular dystrophy, and Christie’s reported that the 2019 auction generated CHF 38,593,000 in total. That means this single Patek accounted for the overwhelming majority of the entire sale’s proceeds. Christie’s
⭐ Why It Matters
The extraordinary irony is that steel helped make the watch more valuable, not less. In ordinary material terms, stainless steel is nowhere near as precious as gold or platinum. But collectors weren’t buying raw material—they were competing for uniqueness, complication, provenance and historical significance.

So, back in 1933, American banker Henry Graves Jr. commissioned the Patek Philippe Graves Supercomplication, a mind-blowing watch that took eight years to make. This double-sided yellow-gold pocket watch packed 24 complications, including a perpetual calendar and a celestial chart of the night sky above his Manhattan home. It was the world’s most complicated watch for a whopping 56 years! It ended up selling for a jaw-dropping $24 million at a 2014 auction. This watch isn’t just about timekeeping; it showcases the brilliant craftsmanship of a bygone era, long before the tech we have today.

Commissioned for American banker and legendary watch collector Henry Graves Jr., the Patek Philippe Graves Supercomplication emerged from an extraordinary horological rivalry with automobile magnate James Ward Packard. Graves wanted a watch of unprecedented complexity, and Patek Philippe responded with a double-sided yellow-gold pocket watch containing 24 complications and roughly 900 components—all conceived in an era before computer-aided design.
Among its astonishing functions were a perpetual calendar, split-seconds chronograph, minute repeater with Westminster chimes, grande and petite sonnerie, equation of time, sunrise and sunset indications—and one particularly personal complication. The reverse featured a celestial chart depicting the night sky above Graves’s Manhattan residence at 834 Fifth Avenue, transforming the heavens over his own home into a mechanical display he could carry in his pocket.
The project required approximately eight years from beginning to delivery, with the watch finally reaching Graves in 1933. At the time it surpassed every previous horological record and became the world’s most complicated watch—a title it retained for 56 years, until Patek Philippe unveiled the 33-complication Calibre 89 in 1989.
Its story became even more extraordinary decades later. Sotheby’s first sold the Supercomplication in 1999 for $11 million, establishing a world auction record. When it returned to Sotheby’s Geneva on November 11, 2014, five bidders fought over it for approximately 15 minutes before the hammer finally fell at CHF 23,237,000—roughly US$24 million—again setting a world record for a timepiece at auction.
💡 Did You Know?
That celestial display wasn’t simply a generic star chart. It was calculated for the sky above Henry Graves Jr.’s own Manhattan home, making one of the most complicated watches ever constructed extraordinarily personal. More than 90 years later, the Supercomplication remains one of the greatest demonstrations of what watchmakers could accomplish using mechanical engineering, mathematics and craftsmanship—without computers.

The Patek Philippe Calibre 89, one of the most complicated mechanical watches ever made, was created in 1989 to celebrate the company’s 150th anniversary. Despite its immense value and complexity, Patek Philippe famously gave away the first of only four examples to the Patek Philippe Museum, rather than selling it. This ensured its preservation as a horological masterpiece for future generations.
The Calibre 89 is a staggering achievement in mechanical engineering, containing 33 complications and an astonishing 1,728 individual components. Housed in an elegant 88.2 mm gold pocket watch case, it features perpetual calendars, sunrise and sunset indicators, a star chart, a minute repeater, a thermometer, and even an equation of time display. It took a team of master watchmakers nearly five years to design, assemble, and regulate each movement, cementing its place among the most complex mechanical timepieces ever created.
Rather than treating the first Calibre 89 as a commercial product, Patek Philippe viewed it as part of the company’s legacy. By donating the inaugural example to its museum in Geneva, the manufacture ensured that collectors, historians, and future generations could appreciate this remarkable milestone in watchmaking. The remaining examples entered private hands over the years, where they have become some of the most coveted and valuable watches ever offered at auction, often commanding prices measured in the millions of dollars.
Today, the Calibre 89 remains a symbol of what traditional watchmaking can achieve when technical innovation is pursued without compromise. It wasn’t created to break sales records or maximize profits—it was built to celebrate 150 years of horological excellence. By placing the very first example in its museum rather than a private collection, Patek Philippe made a powerful statement: some masterpieces are simply too important to disappear into a safe, and are best preserved as part of watchmaking history for everyone to admire.
