The Complete Expression Of A Patek Icon
The Calatrava 3520 is famous for its "Clous de Paris" or hobnail bezel, a signature of Patek Philippe's design language. This example takes that concept to its ultimate conclusion. Instead of a leather strap, the watch is fitted with a fully integrated hobnail bracelet, extending the intricate texture from end to end. Executed entirely in 18K white gold, this configuration transforms the quintessential dress watch into a substantial piece of jewelry, representing a rare and complete vision of the Calatrava design.
A Refined Execution From A Classic Era
Dating to 1970 and sold in 1971, this watch hails from a period of peak refinement for the manufacture. The choice of white gold over the more common yellow gives it a cooler, more contemporary tone that emphasizes the crisp white dial and Roman numerals. It is a more subtle and less expected version of a classic, backed by Patek Philippe extracts that confirm its provenance.
An Excellent And Uncompromised Example
This Calatrava is in excellent condition. The 18K white gold case and integrated bracelet show sharp, well-defined hobnail finishing throughout. The clean white matte dial is free of any cracking or notable imperfections. The bracelet itself is well-preserved, reflecting the overall quality of the piece. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear.
The Ritual Of Pure Watchmaking
This is the definitive choice for a collector who appreciates Patek Philippe's core identity of restrained, perfect design. The integrated bracelet gives it a presence on the wrist that a strap model cannot match, making it feel both elegant and solid. Winding the manual Caliber 175 each morning is a physical connection to the art of traditional watchmaking, a quiet ritual that sets the tone for the day. It is a watch that requires no justification.
