Patek Philippe Calatrava Ref. 3569 – Blue Sigma Sophistication in White Gold

The Patek Philippe Calatrava Ref. 3569 is one of the brand’s most distinctive and unconventional dress watches of the late 1970s. Crafted in 18k white gold, it features a perfectly symmetrical 36 mm case with gently angled lugs and the unusual back-winding crown integrated into the caseback for an exceptionally clean profile.

The highlight is the flawless blue sigma dial, beautifully framed by a finely hammered bezel that adds texture and depth without disturbing the watch’s elegant balance.

Powered by the automatic Patek Philippe Cal. 350, this reference combines technical refinement with bold design details — a rare and highly collectible Calatrava for those who appreciate understated originality.
