An emblematic symbol of Swiss horology’s bold technological leap into the future, this Patek Philippe reference 3597 houses the groundbreaking Beta 21 quartz calibre, the first high-precision electronic movement ever produced collectively by the leading Swiss manufactures. The reference embodies a moment when innovation, design, and prestige converged to redefine modern watchmaking.

The striking blue dial presents a deep metallic sunburst effect that shifts beautifully under changing light, elegantly framed by a minimalist layout featuring applied gold baton indexes and matching slender hands. The generous 18K yellow-gold case offers strong architectural presence with clear, sharp lines characteristic of early 1970s avant-garde design. A leather strap buckle completes the ensemble with refined balance.

Powered by movement No. 6085, this watch represents the earliest evolution of quartz in haute horlogerie, a technical revolution that placed Patek Philippe once again at the forefront of precision and innovation.

The piece is further elevated by the inclusion of original papers, significantly enhancing provenance and collector desirability.

A rare and historically significant Patek Philippe, combining the pioneering Beta 21 technology with a bold sculptural design and a charismatic blue dial, an exceptional opportunity for the connoisseur seeking a milestone reference within the evolution of modern watchmaking.
