Catalogue description
Dealer description — Bulang & Sons
When an oversize watch gets hammered… This a funky and rare manual wind Zenith watch that dates to the 1950s. The case is big, measuring 40mm and made in 18k yellow gold. The watch has very short, unimposing lugs that give the watch a clean circular aesthetic that you cannot help comparing to a classic 50’s sci-fi UFO ! The case is beautifully finished around the outer edge, with a deep lip that has a hammered effect on the gold. The original dial has large applied baton hour markers and non-lume hands. As is a signifier of the watch’s UFO credentials, the dial features an applied Zenith star logo. On the wrist its thinness is cool and the watch lies really large and flat. We love it…it’s out of this world! The manual-wind movement has been fully serviced by our watchmaker and the watch comes on a Bulang and Sons leather strap. Specifications - Zenith Calatrava - Dates to 1950s - 40mm yellow gold case - Original dial and hands - Original winding crown - Comes on a Bulang and Sons leather strap - Fully serviced by our watchmaker - Includes a handmade single leather watch pouch

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.
