The reference 3435 is a particularly elegant expression of Patek Philippes mid-century automatic Calatrava, combining restrained dial design with an unusually distinctive case. Its slender, elongated lugs terminate in subtly rounded tips, lending the watch a refined silhouette that sets it apart from the more conventional Calatrava references of the period.

The present example features a beautiful silvered dial with applied gold baton indexes, a distinctive Arabic numeral at twelve oclock and a subsidiary seconds register at six. Slender hands and a finely printed minute track complete the composition, creating a wonderfully balanced dial that embodies the understated sophistication of Patek Philippes 1960s production.

The yellow-gold case retains attractive proportions, with well-defined lugs and a slim profile that sits elegantly on the wrist. Particularly appealing is the original-style Patek Philippe crown, while the watch is fitted to a brown leather strap with a signed yellow-gold Patek Philippe buckle. Manufactured in 1963, as confirmed by its accompanying Patek Philippe Extract from the Archives, this reference 3435 represents a charming and less frequently encountered interpretation of the automatic Calatrava. Its distinctive case architecture, beautifully restrained dial and classical proportions make it a compelling example of the manufactures mid-century design.
