Catalogue description
Dealer description — Bulang & Sons
Introduced in 1932, the Patek Philippe Reference 96 is the original Calatrava, created during the Great Depression as a simpler, more accessible, and modern wristwatch. Designed by David Penney, its Bauhaus-inspired, minimalist aesthetic helped define the modern dress watch, featuring a 31 mm case, a clean dial, and a small seconds display. It was the first serially produced wristwatch to carry a formal Patek Philippe reference number. Produced from 1932 until 1973, it featured a sleek design with integrated lugs and a flat bezel, embodying the “form follows function” philosophy. Although considered a dress watch, it was produced in a wide variety of configurations, including stainless steel, precious metals, sector dials, and even luminous military-style variants. Presented here is a lovely 18k yellow gold example, with a beautifully preserved case and crisp, clearly visible gold hallmarks. The snap-on case back features an elegant, finely engraved motif—presumably a logo—whose origin remains unknown, adding a touch of mystery and charm. The dial is an opaline silver, with raised enamel signature and a “dot” minute track. It features a small running seconds at 6 o’clock, applied baton-style markers, and is completed by sharp dauphine hands. The watch is paired with the pictured strap and fitted with an AW-signed plaque buckle. The watch and its hand wound movement has been fully serviced by our watch maker.

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.
