Catalogue description

Dealer description — Bulang & Sons

The Portuguese connection… The Omega Ranchero was possibly one of the shortest-run Omega tool watches in the brand’s history. Introduced in 1958, it was only available for two short years and struggled to keep up with the Seamaster, Speedmaster and Railmaster, making it a very rare watch indeed. Aesthetically, it borrows heavily from its sports watch brothers, with the triangle hour markers, arabic 12, 3 & 9 and most noticeably the broad arrow hands. This example is in great condition, with the 35mm case remaining in super condition all round. The patina on this watch is great, although we suspect that the lume in the hands was redone early on, as they still have some radium reading. The watch comes with an archive extract, that states the watch was delivered to Portugal, a fact that is confirmed by Portuguese import stamps on the upper left lug. The watch has been fully serviced by our watchmaker.

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.
