Patek Philippe Grandmaster Chime

With 20 complications and perfect finishes, the extremely exclusive Patek Philippe Grandmaster Chime is one of the most highly coveted watches of all time. It is Patek's most complicated timepiece to date and regularly sets records at auctions.

A Patek Philippe Masterpiece

The Patek Philippe Grandmaster Chime is one of the world's most complicated wristwatches. First introduced in 2014 as part of the company's 175th-anniversary celebrations, this watch boasts an astonishing 20 complications – that's eight complications more than the manufacturer's former most-complicated timepiece, 2001's Sky Moon Tourbillon.

As its name implies, the Grandmaster Chime features several chiming mechanisms, including grand and petite sonnerie and a minute repeater. The date repeater and alarm with chime strike functions also made their world debuts in this timepiece. Additional complications include a second time zone, a moon phase indicator, and a perpetual calendar with a four-digit year display.

The Grandmaster Chime is a so-called "double face" watch, meaning it has dials on both its front and back. While the front-facing dial displays the time and the settings for the chiming mechanism, the back is home to the perpetual calendar. Thanks to its patented reversing mechanism, it's easy to switch between dials.

Reasons to Buy a Grandmaster Chime

  • One of the world's most complex wristwatches
  • Multiple chiming mechanisms, incl. a date repeater and alarm
  • Coveted collector's item with the potential to appreciate in value
  • Patented reversible case with two dials

Prices at a Glance: Patek Philippe Grandmaster Chime

Reference number Price (approx.) Material, dial
6300A-010 (one-off timepiece) 31 million USD Stainless steel & rose gold, black ebony
6300G-001 3.62 million USD White gold, black

5175 2.6 million USD (issue price) Rose gold, silvery gray

How much does a Grandmaster Chime cost?

You should expect to pay upwards of 3.6 million USD for a Patek Philippe Grandmaster Chime. That price will get you the 6300G in white gold – a series-production model. On the other hand, the highly limited first edition ref. 5175R from 2014 is nearly impossible to find. On the rare occasion that one does appear for sale, it usually demands tens of millions of dollars.


About the Grandmaster Chime

To date, Patek Philippe has produced four references of the Grandmaster Chime. The only differences between these models are their case materials and dial colors. All four versions are 47.7 in diameter, 16.07 mm thick, and use the same caliber.

The manufacturer outfits the Grandmaster Chime with the in-house caliber 300 GS AL 36-750 QIS FUS IRM. This movement is comprised of 1,366 individual components and ticks at a frequency of 25,200 vibrations per hour (vph), which is equal to 3.5 Hz. The time display has a 72-hour power reserve, while the chiming mechanism has a power reserve of 30 hours. Considering its 20 complications, the movement is astonishingly compact at only 37 mm wide and 10.7 mm high.

As a sign of its world-class quality, the caliber comes with the Patek Philippe Seal. Movements must pass a series of rigorous tests to earn this quality seal. For example, the movement may only deviate by a maximum of +3/-2 seconds per day. Other criteria include the components' finishes and the quality of the materials used.

Reference 5175: The First of Its Kind

The very first Grandmaster Chime bears the reference number 5175. Patek Philippe worked on this model for seven years before revealing it as part of their 175th-anniversary celebrations. The manufacturer only ended up producing seven of these timepieces, one of which resides in the Patek Philippe Museum.

Beyond its fantastic complications, one of this watch's highlights is its patented reversing mechanism. This technology enables the wearer to flip the case 180° on its own axis, so they can choose which dial faces outward without having to remove the band.

The case and lugs of the Grandmaster Chime 5175 come in 18-karat rose gold. Patek's artisans painstakingly engrave these components with intricate decorations by hand, making every timepiece truly one of a kind.

Other than the watch in the company's museum, little is known about the fate of the other six copies. They are most likely sitting in the hands of anonymous collectors and, thus, will probably never reappear for sale. Even if one of the owners were to decide to sell their Grandmaster Chime, they would likely demand an eight-figure price tag, which is significantly more than the initial purchase price of 2.6 million USD.


The Grandmaster Chime in Series Production

As of 2016, you can find the Grandmaster Chime in Patek Philippe's standard line-up under the reference number 6300G. Unlike the 5175, the 6300G is made of white gold and has polished finishes on its lugs and the top and bottom of its case, while the case sides feature a beautiful, hand-engraved "Clous de Paris" pattern.

To date, Patek has produced two versions of the 6300G: the refs. 6300G-001 and 6300G-010. The former comes with a black dial and matching black alligator strap, while the latter pairs a blue opaline dial with an exquisite navy blue leather strap.

No matter which edition you choose, you should expect to pay around 3.62 million USD for the 6300G.


The World's Most Expensive Wristwatch

The Grandmaster Chime 6300A-010 is the collection's most exclusive model. Patek Philippe created this one-off masterpiece specifically for the Only Watch auction in 2019.

What makes this watch truly special is its use of stainless steel instead of precious metal. Its dials are equally spectacular: While the dial with the displays for the time and chiming mechanisms is made of rose gold, Patek chose ebony wood for the dial with the calendar displays. Finally, the inscription "The Only One" on the alarm subdial underscores this timepiece's exclusivity.

In the end, the 6300A-010 went to an unknown bidder for approximately 31 million USD, making it the most expensive wristwatch of all time. Patek Philippe donated a large portion of the proceeds to the Monaco Association Against Duchenne Muscular Dystrophy (Association Monégasque contre les Myopathies, or "AMM"). This association researches Duchenne Muscular Dystrophy, a life-threatening muscular-degenerative disease that mostly affects children and adolescents.
