Catalogue description

Dealer description — Bulang & Sons

IWC’s Anti-Magnetic Watch The International Watch Co’s Ingenieur was their version of Rolex’s Milgauss and Omega’s Railmaster. The amagnetic watch is housed in a cool sized 37mm steel case, which gives the watch a real presence on the wrist. The case remains in really outstanding condition throughout. The silver dial is in perfect condition – we particularly love the Ingenieur logo on these, with the stylized lightning bolt through the text! The lume dots have turned a rich vanilla colour and punctuate an interesting minute track. The steel hands are cool mix of dauphine and dagger style and add to the watch’s charm. There are lots of subtle and cool elements to this watch – we love it! The watch will come on a generic steel mesh bracelet. This Ingenieur has been fully serviced by our watchmaker.

Historical context

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

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.
