Catalogue description
Dealer description — Bulang & Sons
Moss green from original black… This is a very cool and classic looking vintage IWC dress watch. The steel, snap back case is in excellent condition and has a matte finish with polished bezel. The so-called confetti dial (with multi-colour flecks in the finish) dial would have originally been black but has changed to a moss green colour. The applied hour markers are gold with gold hands with enamel filling. We love this cool vintage timepiece! The watch is fitted with the pictured Bulang and Sons leather strap and the manual wind movement has been fully checked and regulated by our watchmaker. Specifications: - IWC dress watch - 35x40mm steel case - Green colour change confetti dial - Serial 205xxxx dating to 1970s - Manual wind Cal 423 movement - Comes on the pictured Bulang and Sons strap - Fully checked by our watchmaker - Includes a handmade leather watch pouch
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.
