Patek Philippe Watches

Swiss

It shouldn’t be surprising that a Patek Philippe holds the world auction record for a watch ($31.2 million for a Patek Grandmaster Chime, sold at Christie’s). Known for impeccable craftsmanship and some of the most complicated timepieces ever created, the brand is considered by many to be the height of fine watchmaking. Collectors simply love Patek Philippe watches.

The house was founded in Geneva in 1839 by Polish expats Antoni Patek and Franciszek Czapek. Czapek left the firm, and in 1845, Patek partnered with French watchmaker Jean Adrien Philippe. It was the beginning of a beautiful friendship.

Catering to the glitterati of Europe, the pair counted among their clients Tolstoy, Pope Pius IX and Queen Victoria, as well as Countess Koscowicz of Hungary, for whom they created the first Swiss-made wristwatch in 1868. They also had their eye on the American market and in 1851 entered an arrangement with Tiffany & Co. still in effect today.

During the Great Depression, brothers Jean and Charles Stern, who had previously supplied Patek Philippe with watch dials, bought the company, and it continues to be run by the Stern family today.

Under the Sterns, the house has developed some of its most famous models, including the Calatrava, an elegantly minimal dress watch introduced in 1932 and named for the Calatrava Cross (the company’s logo since 1887), and the Nautilus, the brand’s first sports watch, conceived by legendary designer Gérald Genta in 1976.

Despite the house’s longevity, it’s rumored that it has manufactured fewer than a million Patek watches, making each one all the more coveted. (The brand's pieces are understandably attractive to counterfeiters — make sure you know how to spot a fake Patek Philippe watch.)

By Patek Philippe

Located in New York, NY

A More Sculptural Ellipse The reference 3589 represents a specific moment when Patek Philippe took the pure, golden ratio-driven shape of the Ellipse and gave it a more sculptural presence. While many Ellipse models are defined by their minimalist profiles, this 1970s execution features a confident stepped case and a fully integrated woven gold bracelet. This is not just a watch on a bracelet, but a single, continuous piece of jewelry engineered with a clear design vision. It moves the Ellipse from a simple dress watch into something far more ambitious. Automatic Movement, Woven Gold This example brings together several desirable features. It is powered by an automatic movement, offering a level of convenience not found in the more common manual-wind Ellipse references. The integrated bracelet is not only a feat of craftsmanship with its intricate woven texture, but it is also generously sized, a crucial detail for vintage gold watches. The classic blue dial with printed Roman numerals provides a deep, traditional contrast to the warmth of the yellow gold. An Honest Watch In Good Condition Overall, this piece is in good condition. The 18k yellow gold case appears unpolished and is in good shape for its age, showing honest wear. The blue dial has developed a natural patina. The integrated woven bracelet is in great shape, maintaining its structure and intricate finish. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear. For The Considered Collector This is a watch for someone who understands Patek Philippe beyond the hype pieces. The Ellipse has always been the thinking collector's choice, and this reference is a particularly strong representation of 1970s design confidence. It wears with the weight and presence of a solid gold object...

Questions About Patek Philippe Watches

  • 1stDibs ExpertApril 5, 2022
    Patek Philippe quartz watches are battery powered, but automatic and manual winding ones are not. The batteries on quartz watches usually last for a few years before needing to be replaced. Shop iconic vintage and contemporary Patek Philippe timepieces on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    No, Patek Philippe generally doesn't have any non-Swiss parts. The brand produces all of its movements, dials and other components in their own factories located in Switzerland. Producing all of the parts in-house helps the brand maintain an exceptional level of quality. You'll find a large collection of expertly vetted Patek Philippe watches on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    Yes, Patek Philippe does have women's watches available for sale. The brand's signature Nautilus timepiece comes in a slimmer silhouette intended for women. In addition, the brand offers the Twenty~4 Automatic collection exclusively for women. These watches are available in stainless steel and rose gold. Most models feature genuine diamond accents. Shop a range of Patek Philippe women's watches on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    No, Patek Philippe does not use ETA movements in its new watches. However, the brand once did. Early models used movements made by the watch company Lemania. The company that manufactures ETA movements, ETA SA, formed in the late 1970s when Lemania merged with Valjoux, Peseux and other Swiss movement manufacturers. On 1stDibs, shop a collection of Patek Philippe watches.

Depending on the line, you may have your choice of a stainless steel watch with a leather band or metal bracelet. Find a collection of Patek Philippine stainless steel watches on 1stDibs.
  • 1stDibs ExpertMarch 11, 2024
    To check to see if your Patek Philippe is real, look closely at the dial. Any flaw on the dial is evidence of fakery. Are the numbers in the right font? Are the hands the right style and length? Experts recommend that you examine a watch you're considering using a loupe and compare it with the same model in a reference book or auction catalogue.

    Created in-house and by hand, real Patek Philippe cases will feel substantial. There will be nothing slight or irregular about them.

    The time it takes to make a Patek Philippe watch varies based on the model, the assembly of pieces and the sourcing of materials. It’s generally believed that the time varies depending on the complexity of the watch — reportedly, it takes up to nine months for the brand to create one of its more basic models, while a more complicated timepiece will yield a production time of at least two years.

    Yes. Patek Philippe watches are waterproof — some more than others. In 1979, Patek Philippe devised a watch that was fully waterproof down to 120 meters, which was astonishing for the times. However, Patek Philippe dress watches aren’t designed to be in water regularly, but two of its sport watches, the Aquanaut and the Nautilus, are designed for wearing in the water, and they’re water-resistant down to 120 meters. Shop a collection of vintage and new Patek Philippe pieces from some of the world’s top boutiques on 1stDibs.
  • 1stDibs ExpertMarch 11, 2024
    No, Patek Philippe silver dials are not solid silver. The Swiss watchmaker’s dials are most frequently made of brass. The use of the word “silver” in describing a Patek Philippe silver-dial watch is intended to refer to its color, which usually owes to finishing that involves a galvanic painting or enameling process.
