Catalogue description

Dealer description — Craft & Tailored

Gerald Genta is arguably the most celebrated watch designer in history... The Audemars Piguet Royal Oak is arguably his most iconic design... The perception of the Royal Oak shifted as people eventually caught up with the revolutionary design. So much so that it began exceeding expectations, and is now the foundation of the Audemars Piguet brand and the reason for its stratospheric success throughout history. Gerald Genta’s original design and the very first version of the Royal Oak is the reference 5402. Also referred to as the “Jumbo” for its dimensions. With a noble size of 39mm, the original Royal Oak was considered quite large for its era. However, despite the case diameter, the case thickness was only 7mm, a measurement that is still considered thin for an automatic watch by today's standards. This feat of innovation was made possible by the Jaeger-LeCoultre Cal. 920 movement, also known as the Cal. 2121 in the Royal Oak, or the Cal. 28-255 in the Patek Philippe Nautilus, which is also arguably Gerald Genta’s most iconic design. Audemars Piguet still produces a 39mm ultra-thin version of the Royal Oak as a direct celebration of the reference 5402. How does the saying go, “it's what’s on the outside that matters”?... The pièce de résistance, magnum opus, and tour de force for the Royal Oak is the case, bracelet, and dial. Humor aside, vanity is the defining reason for the success of the Royal Oak, it is an unquestionably beautiful timepiece. The Royal Oak was most notably produced in stainless steel with 6,050 units produced in total, of which the first run between 1972 and 1976 was the most collectible of the steel offerings and characteristically known for the “logo down” dials. In 1977 the Royal Oak was reintroduced and officially offered in precious metals, though with diminutive production numbers compared to steel. Only 736 units were ever produced of the 5402 in yellow gold, also known as the 5402BA, with early examples sharing the same “logo down” dial that is so desired from its older steel sibling. Stock # AP5402STA Brand Audemars Piguet Style Royal Oak Model 5402ST Serial A7XX Size Men's Material Stainless Steel Dial Grey "Tapisserie" Millimeters 39 Strap Audemars Piguet "Gay Freres" Stainless Steel Integrated Bracelet CASE & BRACELET The large and beautifully angular stainless steel case shows gentle signs of use and retains excellent factory finishing and chamfers, the case does appear to be very lightly polished in its past. The octangular bezel shows signs of being gently polished as well but retains excellent factory dimensions and angles throughout. The case retains its original unsigned crown. The case back retains all of its original factory markings and engravings in deep and crisp condition. The original integrated stainless steel Gay Freres-designed bracelet retains its original "Audemars Piguet" clasp which also features a 4/72 date code. The bracelet retains 19 links that show almost no stretch and will fit up to a 6 3/4-inch wrist. DIAL & HANDS The original, rare, and truly beautiful Type 1 “Logo Down” dial is exceptionally well-preserved, remaining in virtually flawless condition with only microscopic elements of age at the very edge of the dial that are only nominal in nature. The iconic tapisserie texture is both intricate and precisely executed. The AP logo above the 6 o’clock marker shows a slight discoloration from age but is otherwise flawless. The tritium lume plots have taken on a handsome golden patina and exhibit no degradation when inspected under U.V. light. The hands are later OEM service units that contain luminova lume, this is common for A series 5402s as the original hands were very delicate from the factory. The date wheel displays gentle aging in the text. ACCESSORIES

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.
