Catalogue description

Dealer description — Craft & Tailored

Although Audemars Piguet is now most closely associated with the Gérald Genta-designed Royal Oak, the manufacture had already established a rich legacy of refined and technically accomplished watchmaking long before its introduction. Its mid-century catalog was dominated by elegant dress watches, alongside highly collectible chronographs and complicated pieces, many distinguished by designs that were remarkably forward-thinking for their time. This sophisticated 1970s example embodies that lesser-seen side of Audemars Piguet. Crafted entirely in 18K yellow gold, it pairs a remarkably slim round case with an intricately textured integrated bracelet, creating a seamless and distinctly period design. The restrained gold-toned dial, slender baton markers, and simple two-hand configuration allow the sculptural case and bracelet to take center stage. Powered by the manually wound caliber 2090, the watch measures just 7mm thick, including its crystal, remaining exceptionally thin even by contemporary standards. Elegant without appearing ostentatious, it is a beautifully cohesive expression of understated luxury and the refined craftsmanship that defined Audemars Piguet’s dress watches of the era.

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

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.
