The Ref. 3425 has a beautifully balanced design, with a gently curved bezel, elegant lugs and a two-piece case construction featuring a screw-down caseback. Its proportions are classic without feeling overly formal, giving the watch a discreet presence on the wrist. At approximately 33.5 mm, it retains the refined dimensions that make so many vintage Patek Philippe watches particularly appealing today.

This particular example is crafted in 18k white gold and features an original, Swiss-signed dial in a beautiful off-white tone. Its subtle creamy appearance gives the watch a warmth that contrasts particularly well with the cooler colour of the white-gold case. The dial has retained its original character and is complemented by applied hour markers, matching hands and a subsidiary seconds indication at six o'clock.

What makes this example especially interesting is the combination of its less frequently encountered white-gold case and its beautifully preserved original dial. Compared with the more commonly seen yellow-gold versions, the white-gold reference 3425 has a distinctly understated appearance, while retaining all the qualities that make this reference such an attractive vintage Patek Philippe.

Inside beats the celebrated automatic Calibre 27-460, one of Patek Philippe's most respected movements of the period. Featuring 37 jewels and a solid-gold rotor, the calibre is beautifully finished and represents an important chapter in the development of the maison's automatic movements. It is a movement that combines technical sophistication with the restrained execution for which Patek Philippe is known.

As all our watches undergo a water-resistance test prior to studio photography, we do not remove the casebacks to photograph the movements during this process. Should you wish to receive photographs of the movement, please feel free to contact us. We will be happy to arrange a suitable moment to photograph it at our watchmakers' atelier, after which the watch will undergo a fresh water-resistance test to ensure it is properly sealed once again.

Please note the original white-gold Patek Philippe winding crown, which has developed a beautiful darker tone over time. This natural oxidation can occur when a white-gold crown is left untouched for extended periods. The crown itself is the later-style Patek Philippe replacement, fitted by the manufacture during the watch's service approximately 18 months ago.

Another detail worth pointing out is the original gold import hallmark, located on the side of the case beneath the crown, between the four and five o'clock positions. It remains clearly visible to the naked eye, an increasingly uncommon detail on watches of this age.

As mentioned, the watch was fully serviced by Patek Philippe approximately 18 months ago. More recently, in September 2026, our own watchmakers inspected the movement and carried out a minor regulation. The movement is performing within Patek Philippe's factory specifications and the watch will be delivered with our comprehensive two-year mechanical warranty.

The reference 3425 is a watch that does not rely on size or complications to make an impression. Instead, its appeal lies in the quality of its movement, the thoughtful proportions of its case and the subtle details of the case and dial. In this particularly scarce white-gold configuration, it offers a lovely opportunity to own a less frequently encountered interpretation of one of Patek Philippe's most classic automatic watches from the 1960s.
