Catalogue description
Dealer description — Oliver & Clarke
The Patek Philippe Calatrava. Arguably the brands most iconic model line, and purest expression of the brand. Their raison d'etre if you will. The line has been a hit since its debut in 1932. So much so, that the name "Calatrava" itself has become something of a byword within the watch industry for traditionally styled, no-frills dress watches that simply tell the time. Over the course of its nearly 100-years of production, there have been seemingly countless iterations within the line, with variations in the metal they are made in, with their size, dial configurations, and eventually, complications. The Calatrava that we have here, a Reference 3509, is a not often seen model executed in stainless steel. Dating to circa the mid 1960s, this example remains in strong overall condition with, with a very strong 33mm case, a signed crown, and a screw-down caseback. Inside, th e satin silver dial is wonderfully simple and beautifully preserved, with a clean surface and crisp black text. It has applied 'pencil' indices and a matching 'pencil' handset. Powering this piece is Patek's Calibre 23-300 manual-winding movement. This lesser-known reference is elevated simplicity at its absolute best — the very essence of the Calatrava. And being stainless steel, rare for any Calatrava, makes this very simple piece a real sleeper. There are watches, and then there are watches! This is one of the latter.
Historical context
Modern Mechanical Horology (1945 – 1969)
Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide
Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
