Catalogue description

Dealer description — Bulang & Sons

Designed by Gérald Genta and introduced by Audemars Piguet in 1972, the Royal Oak redefined the luxury watch industry. Widely regarded as the world's first luxury stainless steel sports watch, it arrived during the height of the Quartz Crisis and played a pivotal role in securing the future of traditional Swiss watchmaking. Presented here is the Reference 56175BA, introduced in the 1990s, when ultra-thin quartz watches were at the height of fashion. Thanks to its quartz movement, Audemars Piguet was able to reduce the case thickness to just 5.8 mm, creating an exceptionally elegant Royal Oak that slips effortlessly beneath a shirt cuff while retaining all of the collection's unmistakable design cues. The 33 mm 18 ct yellow gold case remains in excellent condition, with the original factory bevels and sharp lines beautifully preserved. The integrated 18 ct yellow gold bracelet is equally impressive, showing very little wear and currently accommodating wrists up to approximately 19 cm. The cream-coloured dial is wonderfully clean and features a finely printed railroad minute track, a date aperture at 3 o'clock, and beautifully aged cream-coloured lume on both the hour markers and hands. The warm patina complements the gold-printed Audemars Piguet signature perfectly, creating a harmonious and refined appearance. The watch has been fully serviced by our watchmaker, with the quartz Calibre 2612 fitted with a fresh battery, and is ready to be enjoyed for many years to come. Elegant, understated, and increasingly difficult to find in this level of preservation, this yellow gold Royal Oak is a wonderful opportunity for collectors looking for a refined interpretation of Gérald Genta's iconic design. We’ve always felt these ultra-thin, midsize Oaks are somewhat underappreciated. On the wrist, they wear incredibly well—balanced, comfortable, and effortlessly cool. A sleeper in the Royal Oak world, don’t overlook this one!

Historical context

Mechanical Renaissance (1990 – 2010)

Mechanical watches return as cultural objects; independent watchmaking flourishes.

Mechanical watches returned as cultural and luxury objects. Complications, tourbillons and new materials proliferated; independent watchmakers such as George Daniels, F.P. Journe and Philippe Dufour revived artisanal watchmaking; collecting vintage watches became a major field.

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.
