Mike H shares his profound appreciation for the Patek Philippe Ref. 2526, detailing his journey from other Calatrava models to discovering what he considers the 'Queen of all Calatravas.' His review emphasizes the watch's timeless design, rarity, and significant horological features, making a compelling case for its enduring appeal among collectors.
Before starting this review, let’s start with the beginning of the story: my very first Patek Philippe was a 3919: very classy Calatrava with “clous de Paris” bezel and 215 PS caliber. Of course I was thrilled to bits when I got t and I was fascinated by its simplicity and its beauty. This was the beginning of a long story which brought me through several “love stories” (I know I am weak).
Few years later, one day as I was wondering if the 3919 was not so classical that it could become boring, and I was starting to look at some other options. I had already acquired a 3796 in platinum in the mean time with a nice slate grey dial and was then thinking of getting a beautiful vintage. I was strongly hesitating between a 3417 Amagnetic and a 570.
As I was just facing this dilemma, I was fortunate enough to meet a gentleman who mentioned to me that these were surely 2 nice options but the Queen of all Calatravas, the one that he was really fond of was the 2526. This was a true revelation for me and I could not have a rest before I found mine.
Indeed, this watch is not only of a rare beauty with a timeless design, but carries some interesting specifications which all combined make of the 2526 one of the most desirable 3 hands watch:
- it has been made in very limited quantity (man says 580 pieces only would have been made – 480 in YG, 50 in RG, 30 in WG, and 20 in Pt)
- The majority of them have an enamel dial but some examples do have a silver one (however the enamel version is the one particularly sought after by collectors). Some very rare special dials would also have been made with Breguet numeral, diamond dial (for Pt and WG) or black enamel dial with baton markers. Not only enamel dials are always rare – and in PP collection particularly – but also many of them have been damaged or broken at the occasion of maintenance service thus leaving few in perfect condition with no hairline cracks.
- The movement was Patek Philippe’s 1st self winding movement, the 12-600-AT. The 12 stands for 12 lignes the movement’s diameter, the 600 denotes the movement overall height in mm, the AT stands for Automatic. The movement is 30 jewels, bi-directional winding, Gyromax balance and is stamped with the Geneva Seal. The 18k gold winding rotor is signed with 'PP 18K' and 'PATEK PHILIPPE GENEVE' and is decorated with barleycorn guilloche
- One of the first (if not the first) waterproof screwed back case of Patek Philippe: the case back is a massive screw down chunk of 18k gold which is designed to prevent water, humidity and dirt intrusion
- Although not specific to the 2526, I particularly like the special crown with double P back to back
In short I love it and still find it very actual in spite of its age: its 36 mm size and design are timeless.
I forgot to mention it: its “PP birth certificate” states it has been manufactured in 1956.
But to fully understand only pictures can speak:
Classic oversized (for the period) Calatrava case with 36mm diameter

Typical Patek Philippe dial with its well balanced proportions



The screwed back case is a massive screw down

In the meantime have a great week.

The Patek Philippe reference 570 is a classic Calatrava-style dress watch, representing a significant period in the brand's production of time-only pieces. It is distinguished by its clean lines and minimalist aesthetic, embodying the traditional design principles that Patek Philippe is known for in its non-complicated watches. The reference 570 was offered in various metals and dial configurations, making each example unique within the broader series of Patek Philippe's round cased watches from the mid-20th century.
This particular example features an 18k white gold case with a diameter of 38mm. It is fitted with a sapphire crystal, protecting a silver dial. The watch is powered by a manual wind movement, reflecting the common practice for high-end dress watches of its era. The water resistance is rated at 30 meters, typical for a watch of this type and period.
The reference 570 appeals to collectors seeking a pure expression of Patek Philippe's watchmaking heritage, particularly those interested in the brand's foundational dress watch designs. Its various iterations, including different case materials and dial finishes, offer a range of options for discerning collectors. The enduring appeal of the 570 lies in its understated elegance and its representation of a specific era of Patek Philippe's design philosophy.
The pics, the text and the watch are a pleasure to view and read. I can feel the love you have for this piece, and yes, you're right, it is tilmeless, even if I find that the colored gold case gives it a nice Retro Touch. Thanks for the time you spent on this articie. Best, Nicolas
Yes I love this watch more than all others you are right. I don't know why, it has something very special like no other one, a kind of magnet. And it is a real pleasure to take the time to make some nice pics and write about a watch like this one for sharing here. Best, Mike
I really hope it never happens, but if I would have no other choice but to keep only one watch and no other one, it would be this one!
