Gerald Genta Rolex King Midas Ultimate Guide

The Rolex King Midas is a legendary limited edition timepiece designed by Gérald Genta in the early 1960s. Carved from a single block of 18k gold and inspired by the Greek Parthenon, it was the heaviest gold watch of its era.

At the time of its release, the King Midas was also the most expensive watch in the Rolex lineup. It cost nearly twice as much as a solid gold Day-Date at just under $3,000.

What started as a standalone limited series eventually became part of the Cellini family. However, the original reference 9630 remains a cult classic for serious collectors. Elvis Presley owned one. So did John Wayne and the fictional James Bond villain Scaramanga.

Today the King Midas is one of the most unusual vintage Rolex watches.

This guide explores why this unconventional Rolex has increased in value and popularity among collectors who appreciate watches that break the mold.

History and Origins: A Gérald Genta Design

Rolex asked a young Gérald Genta to design a gold watch fit for a king back in the 1960s. Now keep in mind, this was years before Genta would go on to create the Audemars Piguet Royal Oak in 1972 or the Patek Philippe Nautilus in 1976. The result was the King Midas. It took its name from the mythological Greek king whose mere touch turned objects into solid gold.

Rolex is also well-known for its rugged tool watches, like the Submariner and Explorer. But the King Midas is nothing like those watches. It was designed more as a jewelry watch or a status symbol. Instead it was crafted to make a statement on the wrists of the elite. Genta took inspiration from the geometric designs of ancient Greece. He created what many consider his earliest masterpiece for a major watch brand.

Design Features: The Midas Touch

The design of the King Midas sets it apart from anything else in the Rolex catalog. It’s wearable art. The asymmetrical case, the placement of the crown. Every bit was intentional and inspired by Green mythology.

The Asymmetrical Case and Bracelet

The King Midas doesn’t look like any other round-cased Rolex. The case is five-sided, sharply angular, and almost architectural. Tilt it with the crown pointing up and it takes the shape of a Greek temple, the grooved bracelet links representing the columns beneath it. Rolex was clearly thinking about the Parthenon here. But instead of making something literal, they turned the idea into a solid block of sculpted gold.

The integrated bracelet uses a brick-link style construction with flat links measuring just under 4mm thick. This nearly matches the slim profile of the case itself. Early references like the 9630 and 3580 featured a double deployant clasp with Rolex crowns on either side. Later models used a single fold-over clasp. The hidden clasp design maintains the seamless appearance of the bracelet. Inside the clasp you will find the engraving “King Midas by Rolex of Geneva”.

The Left-Handed Crown

You’ll probably instantly notice the crown sitting at 9 o’clock instead of the usual 3. It’s unusual for Rolex, and even today it catches you a bit off guard.

It’s tied directly back to Greek mythology. As the story goes, everything King Midas touched with his left hand turned to gold, so Rolex positioned the crown on the left side of the case, encouraging wearer to sport the watch on their right wrist.

The crown is special, too. It’s shaped like a sun with saw-toothed edges to make it easier to grip. The words “King” and “Midas” are deeply etched into the gold case on either side of the crown to add another layer of detail.

The Dial and Crystal

In contrast to the bold case and bracelet, the dial is remarkably simple. It features only the essential elements. There’s the hour and minute hands and the Rolex crown logo at 12 o’clock. On the original Ref. 9630 you also see the Greek letters “ΜΙΔAΣ” (Midas) at 6 o’clock. Later Cellini versions replaced the Greek lettering and added “Genève” below the Rolex logo.

The King Midas was also one of the first Rolex models to feature a sapphire crystal. In fact, this watch was using sapphire to protect the case long before Rolex made it the norm on sport models. Back in the mid-’60s, that wasn’t common. Acrylic was still the industry standard. Rolex set the crystal flush with the case, making the profile clean and low rather than bulky.

The Urn Box

Even the packaging was different. Instead of the standard green Rolex box, the King Midas came in an amphora-shaped case modeled after a Greek urn. It felt more like opening an artifact than a watch. The outer box featured gold and white cardstock decorated with Grecian figures depicting battle scenes. The inner box was crafted from black wood with red embossing in the style of ancient Greek vase paintings.

This box has become a highly collectible item on its own. While the boxes could once be found for one or two thousand dollars, complete examples with the urn have reportedly sold for well over ten thousand dollars recently. According to collectors, the original box can significantly impact the value of a King Midas set.

Production Numbers and Reference Guide

The early Ref. 9630 isn’t just another Cellini variation. It’s a rare, limited-edition watch, finished by hand, so no two will ever be identical in weight or finish. Flip the bracelet over, and you’ll see the production number engraved near the case.

The later Cellini versions started with the Ref. 3580 and were integrated into the Rolex dress watch collection. These models can be identified by production numbers of 800 or higher. They also include “Genève” or “Cellini” markings on the dial. These watches have the same silhouette, but they’re generally considered less collectible than the original 9630. However the Ref. 3580 is actually rarer with an estimated production of only 500 pieces.

Reference & Era | Classification | Key Distinctions
Ref. 9630 (1964 – c. 1972) | King Midas (Limited Series) | The original model limited to fewer than 800 pieces total. Dial reads “ΜΙΔAΣ” in Greek. Typically lacks “Genève” on the dial. Heaviest version at approximately 190g or more.
Ref. 3580 (c. 1972 – 1977) | Cellini King Midas (First Mass Production) | Integrated into the Cellini line. “GENÈVE” added to dial below Rolex logo. Even rarer than the 9630 with approximately 500 pieces produced.
Ref. 4315 (Late 1970s) | Cellini King Midas (Updated Movement) | Powered by the thinner Caliber 651 movement. Features an updated flatter folding clasp and thinner bracelet measuring approximately 3mm.
Ref. 4017 (Late 1970s – 1980s) | Cellini King Midas (Asymmetrical Variant) | Part of the broader Cellini King Midas family. Features the asymmetrical case design with various dial options, leather straps.
Ref. 3581 (Various) | Queen Midas (Ladies Variant) | Smaller 23mm case size. Identical asymmetrical design and saw-toothed crown scaled down for women.

Famous Owners and Pop Culture

The King Midas wasn’t just sitting in display cases. It ended up on some very famous wrists, which only added to its reputation as a watch for people who didn’t want something ordinary.

Elvis Presley: The King of Rock and Roll owned yellow gold Rolex King Midas No. 343. It was a gift from the Houston Livestock Show Officers after Elvis performed six consecutive sold-out shows at the Houston Astrodome in 1970. Elvis reportedly loved the watch so much that he wore it swimming and bathing. This caused some degradation visible on the dial. Today this watch sits on display at Graceland in Memphis.

John Wayne: The legendary actor known as “The Duke” owned King Midas No. 557. His watch was sold in 2011 during a personal property auction. It fetched $26,290 which was more than three times its pre-sale estimate.

Francisco Scaramanga: The villain played by Christopher Lee in the 1974 James Bond film The Man with the Golden Gun wore a King Midas on screen. It fit perfectly with his character’s golden gun and obsession with gold.

Modern Era: The King Midas has experienced a resurgence recently among contemporary celebrities. Rihanna and The Weeknd have both been spotted wearing customized versions. This introduced the watch to a new generation of collectors.

Specifications: Movement and Materials

Weight: Between 150g and 200g depending on reference.

Movement: Caliber 650 or 651. Based on the ultra-thin Frédéric Piguet design with a height of just 1.8mm.

Mechanism: Manual wind rather than automatic. This allows for the ultra-thin case profile.

Jewels: 17 to 18 jewels depending on caliber.

Case Material: 18k yellow gold or 18k white gold.

Case Dimensions: Approximately 27mm to 28mm wide and less than 5mm thick.

Crystal: Sapphire. One of the first Rolex models to use this material.

The manual winding movement was an intentional choice. An automatic rotor would have added thickness to the case. This would compromise the slim bracelet-like profile that makes the King Midas so distinctive. The thin caliber combined with solid gold construction allows the watch to sit close to the wrist like fine jewelry.

Price and Collectability: Is It a Good Investment?

The King Midas spent years as an undervalued oddity in the vintage Rolex market. Collectors favored sport models like the Submariner and Daytona. This left the King Midas in relative obscurity. That’s has changed in recent years, though, with renewed interest in watches with integrated bracelets like the Royal Oak and Nautilus.

Prices for a vintage Rolex King Midas vary based on reference and condition. Based on completed sales at Bob’s Watches here is what collectors can expect to pay:

Ref. 9630 (White Gold): $30,000 – $80,000

Ref. 9630 (Yellow Gold): $80,000 – $95,000

Ref. 3580: $12,000 – $90,000 (yellow or white gold)

Ref. 4315: $65,000

Ref. 4017 (Cellini King Midas): $12,000 – $15,000

Pristine Ref. 9630 examples in yellow gold with original boxes and papers can command close to six figures at major auction houses. John Wayne’s watch sold for $26,290 in 2011. Given the appreciation in the vintage Rolex market since then, comparable examples would likely fetch significantly more today.

Collectors should be aware that finding an unpolished King Midas is difficult. The softness of 18k gold means most examples show signs of polishing over the decades. This can reduce value for purists. Complete sets with the original amphora box and paperwork are highly prized and can increase the overall value of a watch.

The Golden Legacy Reimagined

The King Midas is the anti-Rolex. It is not a rugged Oyster built to withstand the elements. It is a brutalist masterpiece of jewelry design that represents a time when Rolex took massive avant-garde risks.

In an era defined by tool watches, Rolex created something that was purely about aesthetics and luxury. The King Midas proves Rolex can compete with the best of the watchmakers out there.

The King Midas isn’t the kind of watch you buy casually. With its rarity and rising values, they aren’t exactly floating around the market. That’s why authentication is key. Every watch we sell at Bob’s Watches is verified in-house, so collectors can buy with confidence instead of second-guessing their purchase.

The Midas is a rare find. If it’s the gold Rolex aesthetic you’re after, though, the Day-Date and certain Cellini references offer a different expression of that same general heritage, just in a more traditional case design.

Frequently Asked Questions
The original reference 9630 was produced in fewer than 800 pieces total. Approximately 144 were made in white gold and the rest in yellow gold. While often cited as limited to 1,000 pieces, research suggests actual production was lower. Later King Midas Cellini models were produced in larger numbers but remain relatively rare compared to standard Rolex models. The Ref. 3580 is estimated at approximately 500 pieces. Some of the factors that set the King Midas apart are the asymmetrical pentagonal shape inspired by the Parthenon, its history as an early Gérald Genta design, its manual-wind movement, and the left-sided crown that honors the legend of King Midas. It was also one of the first Rolex watches to feature a sapphire crystal and was the heaviest gold watch on the market when released. It depends on the era. The original Ref. 9630 released in 1964 was simply called the “King Midas” and predates the Cellini collection. Later references starting with the 3580 in 1972 were integrated into the Rolex Cellini collection to distinguish dress watches from the waterproof Oyster Perpetual line. Yes.
