Catalogue description

Dealer description — Craft & Tailored

Zenith is one of the few watchmakers arguably better known for its movements than its watches, a reputation built largely on the legendary El Primero, among the world’s first automatic chronograph calibers and famously used in the first automatic Rolex Daytona. Introduced in 2022, the DEFY Skyline translates that high-frequency heritage into a thoroughly modern sports watch. Its angular stainless-steel case and faceted bezel draw inspiration from the octagonal geometry of early DEFY models, while the black patterned dial incorporates Zenith’s emblematic four-pointed star. At 9 o’clock, a constantly running indicator completes one rotation every 10 seconds, displaying tenths of a second directly from the movement’s 5Hz frequency. Visible through the exhibition caseback, the automatic manufacture Caliber 3620 operates at 36,000 vibrations per hour and pairs efficient bidirectional winding with a 60-hour power reserve. Offered with its original box and papers, this 2022 example delivers a compelling blend of Zenith’s technical legacy, distinctive design, and everyday versatility.

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.
