Catalogue description

Dealer description — Oliver & Clarke

It’s not unfair to say that Audemars Piguet Royal Oak is one of the most iconic watches ever made. Designed in 1972 by Gerald Genta, the Royal Oak completely changed the way that we look at a steel sports watch. For the first time, stainless steel was treated as a precious metal - receiving complex finishing techniques of brushing, polishing, and beveling - all by hand. The idea that its eight hexagonal bezel screws would be finely finished and left exposed for the wearer to see was a revolutionary thought. It’s no surprise that the model became the calling card for the family owned Audemars Piguet - not to mention one of the most sought after watches in the world. While the initial 5402 was time-only, AP quickly began to capitalize on the success of the Royal Oak and begin to integrate other complications and variations into this case. Which leads us to the Royal Oak that we have here, a 'midsize' Reference 4100SA. These pieces embody the ethos of the original Ref. 5402 'Jumbo' models, just in a slightly smaller and equally svelte 35mm case. In fact, at a glance, the only thing that differentiates it from its larger sibling, is the presence of a running central seconds hand. This particular example dates to circa 1979 and comes to us in strong overall condition. The case, matching two-tone integrated bracelet, and characteristic octagonal bezel show normal signs of wear throughout with visible factory finishing. The grey micro-tapisserie dial within exhibits minimal wear to the textured surface and presents excellent, with the applied Tritium-filled indices and matching handset evenly patinated as well. Flip it over and there is a small, unusual engraving that reads: "Or et acier" — French for "gold and steel." Without a doubt, two-tone watches are polarizing... However, there is something about a two-tone Royal Oak, in any form, that just works. The two metals are perfectly distributed in the form of the bracelet links, the bezel, and the dial components, and amount to a very well-rounded wearing experience. The 35mm size lends itself to, we think, a more comfortable wearing experience for more people, in fact, we'd say virtually any wrist, versus the way a full size 39mm Royal Oak which can fit a little odd on some wrists due to how flat it is. These watches strike the perfect balance between the size and value proposition that a Royal Oak can offer.

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.
