3 Most rare Patek Philippe Watches of all time
Patek Philippe has made over 200 watch models since its inception but these are the three timepieces that are the rarest and are highly sought-after by watch collectors. Let’s have a look at the 3 of the most rarest Patek Philippe Watches of all time.
1. Patek Philippe Ref. 1518

The Patek Philippe Ref. 1518 is a rare collector’s item, first released to the public in 1941 and limited to only four examples.
It is one of the world’s most sought-after chronographs and is considered by many as a benchmark for mechanical watchmaking excellence.
Its investment value and rarity appeal have made it an extremely desirable item among collectors of vintage watches.
The piece was recently auctioned off for over $11 million, making it the most expensive wristwatch ever sold at that time.
It features two sub-dials, a date display at 3 o’clock, and a moon phase indicator at 6 o’clock – all powered by its Caliber 13-130 manual winding movement with a power reserve of 45 hours.
Patek Philippe also produced another model from this series – Ref. 1579 – which is even rarer than Ref. 1518 since only three units were made in 1943-44 and none have ever been sold publicly since then.
2. Patek Philippe Ref. 2499

The Patek Philippe Ref. 2499 is a highly sought-after watch due to its unique history and craftsmanship.
First produced in 1951, the Ref. 2499 has been released four times, making it one of the rarest watches manufactured by Patek Philippe.
Each version was made with an 18K Gold case and a perpetual movement that displays time in both a 12-hour and 30-minute format, making it an exclusive item for collectors who appreciate luxurious complexity.
3. Patek Philippe Ref. 3970

A highly sought-after collector’s item, the Patek Philippe Ref. 3970 stands out as an iconic timepiece for its intricate design and exclusive nature.
It was first released in 1986 and is a perpetual calendar chronograph, making it particularly unique in the world of watchmaking.
The watch boasts a range of features such as moon phases, leap year cycle, day of week display, month display, and even minute repeater.
However, its price points have prevented many from owning one – typically ranging between $50K-$250K depending on the condition and edition type.
Additionally, limited editions have been released over the years which further add to its exclusivity amongst collectors.
Other rare models include:
- The Sky Moon Tourbillon Ref 5002P with two faces and manual winding movement
- The Henry Graves Supercomplication pocket watch with 24 complications
- The Platinum World Time reference 5110P with perpetual calendar and moon phase display
- The Caliber 89 Pocket Watch with 33 complications including seven hands in four subdials
These types of watches are not only coveted due to their rarity but also because they represent some of the finest examples of watchmaking craftsmanship in the world.
Conclusion
The Patek Philippe watch company has produced a number of rare and valuable timepieces.
The Ref. 1518, released in 1941, was the first perpetual calendar chronograph wristwatch ever made. Its stainless steel case and simple design make it a highly desirable piece for collectors.
