Catalogue description
Dealer description — Bulang & Sons
All shapes and sizes… It seems that 2022 has, so far, been the year of the Defy for Zenth, as they have expanded their line considerably, including a re-edition of the original Defy from 1969. This classic vintage Defy, with the octagonal case with scalloped edges and, on this model, a 14-sided bezel. The case and bezel remain in fantastic condition. The matte silver dial has ‘doorstop’ applied hour markers and cool rectangular lume plots on the outer edge of the dial that have taken on an awesome yellow patina. The hands are a shade lighter and although tritium, we believe the seconds hand may be relumed. The watch is fitted with its very rare original double-signed Ladder bracelet that was manufactured by Gay Frères, with a clasp stamped ‘4 69’ and ref Z6 endlinks.

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.

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.
