Catalogue description

Dealer description — S.Song Watches

The IWC Cal. 89 is the quintessential vintage dress watch. Minimal in its design and high quality, this is the dress watch that in my opinion, presents the best value. This watch is housed in a classic 36mm rose gold case with beautifully elegant ‘bombe’ lugs and features a snap down caseback. The silver brushed dial is very simple and elegant, with applied pointed index markers and a dotted minute track. It has matching gold stick hands and of course the classic International Watch Co script logo which many people have come to love. Beating inside this watch is the immensely high-quality Cal. 89 movement. It is an in-house movement produced by IWC that was used most famously on the military RAF Mk 11 models. As it was deemed good enough to be used by military pilots, you can imagine the quality and timekeeping this movement is capable of. The Cal. 89 is regarded as one of the greatest movements of the era. If you are looking for an understated, elegant dress watch, I would certainly suggest this IWC Cal. 89 as a contender. This example in particular, is remarkably preserved, especially with its original dial as most examples have been refinished.

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.
