The Ref. 3509 combines both contemporary and the famous vintage Bauhaus elements, from the design of the steel case to the rare pattern on the dial.
The more than 60-year-old Patek is, as you can see on our pictures, in amazing unpolished condition. It breaths class and a distinguished style.
Patek Philippe dress watches are usually made out of precious metals. It is only on rare occasions that you find a steel one. So this Ref. 3509 is very limited produced between +/- 1960 and 1969. A rough indication of the rarity of steel Pateks around this production era: Ref. 1518, +/- 280 watches were produced, only 4 were made with a steel case.
With a case size of 34mm, the watch wears at least 2mm larger than its dimensions would suggest. Because of the straight lugs, the perfectly circular case with the wide-set smooth bezel that gives the watch a larger presence on the wrist. The recognizable Patek crown bears the famous Calatrava cross.
The brand new and unworn Black croco strap from Patek Philippe is fitted with a new steel Patek Philippe tang buckle.
The dial is in perfect proportians and is applied silver hour indexes are finished with a polish with multiple facets. The "Patek Philippe Genève" logo has subtle serif details, which is a typical distinctive vintage aesthetic. In particular, the accent on the "è" of "Genève" is a feature most attributed to the Patek’s earlier pieces. The acrylic crystal is also in great condition and give the watch that warm and vintage vibe.
