ref.1526
Yellow, Perpetual Calendar

A fine and rare 18K gold perpetual calendar wristwatch with moon phases.
Ref.1526, certainly Patek Philippe's most elegant and timeless simple perpetual calendar wristwatch, was launched in 1941. Highly appreciated by collectors, the model is immediately identifiable by its Calatrava-style case. According to literature, as few as 210 examples were made, cased either in yellow or pink gold and only one example in steel, now at Patek Philippe's prestigious watch museum in Geneva.
The present watch is from the second generation of reference 1526, distinguished by the design of the subsidiary seconds indication surrounding the moon phases: it features small hard enamel baton scales as opposed to the Arabic numerals of its predecessor and is "open" towards the moon side whereas the earlier series featured a so-called double "chemin de fer" or "railway" circle.
