Catalogue description
Dealer description — Somlo Antiques
Introduced in 1949-1950, the 12-400 is the known successor to Patek's famous 12-120 calibre. While maintaining the essential architecture, the 12-400 incorporated several critical improvements, including a redesigned regulator system enhancing the overall reliability. These refinements elevated the movement from a delicate dress-watch caliber into a far more versatile platform, capable of meeting the rigors of mid-century wristwatch use. Patek Philippe produced fewer than 100 to around 600–1,000 total pieces (including related variants like the 3418 A and 3419) that were manufactured between 1958 and 1962. • First Series (1958–1960): Approximately 200 pieces made (using the calibre 12-400 or calibre 12-AM 400 movement). • Second Series (1960–1962): Approximately 400 pieces made (using the calibre 27-400 or calibre 27-AM 400 movement). Brand: Patek Philippe Made: 1960 Model: Calatrava Reference: 3418 Calibre: 12-400 Movement: Manual Material: Stainless steel Features/complications: Antimagnetic movement Dial: Silvered dial featuring outer minute track with applied mirror polished baton shaped hour indices with Baton hands and sub-seconds dial Case dimensions: 34mm Bracelet/strap: Stainless steel bracelet Accessories: Extract from the Archives SKU: 3536
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.
