Details
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.

What Our Clients Say About Us

I knew I was gonna like Danny, based on his name, but nothing could’ve prepared me for how great of an experience this was. He had the most beautiful 70s Seamaster Cosmic on his website and I was set to be married 2 days later - I arranged to buy it but before leaving we both realized it needed to be serviced. I panicked, because I was literally buying this for my wedding, and Danny being the legend he is, loaned me a nearly identical Seamaster to make sure I could get through the event Never have I had someone go so above and beyond for me, especially while purchasing one of the lesser priced items in their inventory. He serviced my watch and exchanged it with me after the wedding on a super fast turnaround timeline. I would sincerely recommend you visit this guy, you will not be disappointed Edit: adding a pic of the loaner (two tone) and the owner (crosshair)

Great service and shop. Danny and his team were incredibly accommodating, professional, and kind. Great selection of vintage watches. Their store is the hidden gem in the diamond district.

This was my first real luxury watch purchase, a Rolex 15200 Date 34mm, I own Tissots and a Laco, but those are entry level luxury watches. I found Danny’s Vintage Watches online, and had great feedback both on Google, Chrono24 and the Reddit watch community. So decided to give him a shot as buying online can be a crap shoot. Ordered Monday night, was at my doorstep Friday morning. Despite the watch being over 30 years old, serial number says it’s from 91, the watch looked new. Didn’t come with box or papers, and was shipped in a plastic sleeve wrapped in bubble wrap. Danny was always available to answer questions. I’ll be buying from Danny again for the next purchase…saw a couple of Speedmasters on his site I liked….
