The most expensive wrist watch in the world is the Graff Diamonds Hallucination, priced at 55 million dollars. It was revealed by Graff in 2014 and the case, bracelet and dial are nearly completely encrusted with rare pink, blue, green, orange diamonds, a total weight of over 110 carats. It has never been sold at auction, it is not subscribed. The $55 million number is Graff’s retail value. Nevertheless, no other sold or unsold watch can match it.

Why Do Some Watches Cost More Than a House?

Take a poll of ten watch collectors for reasons a watch is worth millions and you’ll get ten slightly different answers. There are a handful of things that do keep recurring.

• Rare materials- Either large, matching colored diamonds or certain gold alloys are not readily available, and that is reflected in the cost.
• Complications- Inventions such as perpetual calendars, minute repeaters or star charts are designed and made by watchmakers over years—decades — of work.
• Provenance- It is important who it is. There’s a story that a watch tied to a famous name can’t tell.
• Scarcity- Off the shelf or mini-production always fetches a higher price.
• Brand weight- Compacts such as Patek Philippe, Breguet and Vacheron Constantin are known over 150 years and the price reflects this history.

This is not enough alone to break a record. It is typically 2-3 of them layered on top of each other.

The Watch That Holds the Record

Graff Hallucination isn’t your average watch, and, as the name suggests, calling it a “watch” doesn’t really do it justice. It is a showcase for Baselworld of 2014 and Graff has maintained the model created in-house ever since. It is an actual retail sale, so it’s the priciest watch ever sold, but not the cheapest. A lot of people get this one confused—it’s the most expensive watch made not the most expensive one sold, held by two very different watches.

The Most Expensive Watch Ever Sold at Auction

That second record goes to the Patek Philippe Grandmaster Chime Ref. 6300A-010, which sold for 31.19 million dollars at the Only Watch charity auction in Geneva in 2019. Patek usually makes the Grandmaster Chime in rose or white gold. This one was steel — a material the brand almost never touches for its top-tier complicated pieces — and it was a one-of-one, made specifically for charity. Put those two facts together and you get exactly the kind of watch collectors lose their minds over.

It backs that rarity up mechanically, too. Twenty complications, a reversible case with two separate dials (one for time, one for the calendar and alarm), and both a grande and petite sonnerie — two of the hardest chiming mechanisms to engineer correctly.

Other Records Worth Knowing

A few other watches round out the top of the list, and each got there a different way.

• Paul Newman’s Rolex Daytona Ref. 6239 sold for 17.75 million dollars at Phillips in New York in 2017. His wife, Joanne Woodward, gave it to him, and the caseback still reads “Drive Carefully Me.” Newman’s Daytona originally cost a few hundred dollars. Ownership alone did the rest.
• Patek Philippe Ref. 1518 in stainless steel went for roughly 17.6 million dollars at Phillips in Geneva in late 2025. Only four steel examples are known to exist, which is really the whole story right there.
• Breguet’s Grande Complication Marie Antoinette is valued around 30 million dollars. It was commissioned in the late 1700s and took over 40 years to finish — the watchmakers involved didn’t live to see it completed.
• Jacob & Co.’s Billionaire Timeless Treasure sits around 18 to 20 million dollars. It’s closer in spirit to the Graff piece than to a traditional dress watch — more jewelry than horology, but a working movement all the same.

So Why Do People Actually Buy These?

It’s a fair question. A watch this expensive isn’t really about knowing what time it is.

For a lot of collectors, it comes down to respect for the craft. Building something with 20 complications takes a small team of specialists years, and buying one is partly a way of keeping that kind of work alive. Others treat it more like an asset. The Patek Philippe 5207P, for example, has more than doubled in value within a few years of release — that kind of appreciation gets attention from buyers who care about resale as much as wrist time.

And then there’s the story. A watch connected to a real event or a well-known name carries weight nothing else can fake. That’s the whole reason a Rolex that once cost a few hundred dollars is now worth 17.75 million.

Final Thought 

The Graff Diamonds Hallucination holds the top spot most expensive wrist watch in the World: 2026 Ranking & Facts at 55 million dollars, though it’s a valuation, not a sale price. For an actual auction result, the Patek Philippe Grandmaster Chime takes the record at 31.19 million. In between, you’ve got watches that earned their price through rare materials, serious engineering, or, in Paul Newman’s case, sheer star power. You probably won’t own one of these. But knowing what separates a good watch from a record-breaking one tells you a lot about what collectors actually value — and it’s rarely just the time on the dial.
