Catalogue description

Dealer description — Watches of Knightsbridge

A refined example of mid-century Patek Philippe craftsmanship, this 1957 Patek Philippe Calatrava Ref. 2545 is distinguished by its exceptional presentation on an 18ct yellow-gold brick bracelet crafted by Ponti Gennari, one of Geneva’s most celebrated specialist goldsmiths and historic collaborators of Patek Philippe. Founded in Geneva, Ponti Gennari developed a reputation for producing highly refined precious-metal bracelets and jewellery creations, working closely with Patek Philippe during the golden era of vintage wristwatches. Their bracelets were not generally standard production fittings, but were typically special-order creations, individually commissioned to complement the elegance of Patek Philippe’s finest dress watches. Known for their exceptional craftsmanship, intricate construction, and luxurious finish, Ponti Gennari bracelets are now regarded by collectors as rare and highly desirable works of Geneva jewellery art. The bracelet’s supple brick-link construction provides both comfort and visual presence, offering a striking contrast to the understated sophistication of the Calatrava’s classic round case. The relationship between Patek Philippe and Ponti Gennari represents an important chapter in the Maison’s history of collaborating with specialist Geneva artisans; the firm was later renamed ARSA before being integrated into Patek Philippe’s own workshops. A rare and elegant vintage timepiece, combining the purity of the Calatrava design with the exceptional craftsmanship of one of Geneva’s most revered bracelet makers. The dial on this watch has been professionally refinished.

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.
