Catalogue description

Dealer description — Vintage Watch Specialist

A Beautiful and Unusually Opulent 18ct Gold IWC Dress Watch with an Aftermarket Diamond Bezel in Superb Condition, c.1978 The International Watch Company (IWC), founded in 1868 by American watchmaker Florentine Ariosto Jones in Schaffhausen, Switzerland, is renowned for its precision engineering and timeless elegance. Jones aimed to blend advanced American production techniques with skilled Swiss craftsmanship. IWC's journey began with the development of high-quality pocket watches. In the early 20th century, IWC pivoted to wristwatches, gaining recognition for robust models designed for aviators. The 1936 release of the IWC Pilot’s Watch marked a significant milestone. Post-World War II, the IWC Portugieser series emerged, characterized by its large case and clear design, appealing to maritime navigators. The 1980s saw innovation with the Da Vinci line, featuring the first Swiss-made chronograph with a perpetual calendar. Today, IWC blends heritage with modern technology, producing iconic collections like the Aquatimer, Ingenieur, and Portofino, all celebrated for their elegance and technical prowess. This blend defines IWC as a pioneer in luxury watchmaking. What's on Offer My boss has a saying 'Find me another' when he is excitedly presenting a unique watch that he cannot find another example of! This is one of those watches... I simply cannot find another the same as this anywhere, just look at that jumbo TV case in solid gold with (what we think) is an aftermarket diamond bezel! At 40mm wide this is a very substantial watch for the time of its production and it looks absolutely stunning on the wrist. It is opulent without being ostentatious even though it is crafted from 18k gold and boasts that beautiful bezel. The dial is blemish-free and has a subtle texture with beautiful applied furniture comprising slim baton hour markers with onyx inserts and corresponding hands. There is a subtle date wheel at 3 o'clock which is neatly framed in gold. The integral tapered bracelet is also crafted from 18k gold and is in superb condition. We are delighted to offer such an exquisite watch for sale in outstanding condition. As I say, we cannot find another watch like this so if you love it like we do, don't sleep on it!

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.
