Catalogue description

Dealer description — Craft & Tailored

Universal Genève created its first chronograph i n 1917 and roughly 18 years later, they launched their first “Compax” in which many variations were to follow. Vintage Universal Genève’s sports watches are particularly sought after thanks to their variety, unique designs, and larger sports watch case sizing. Although Universal Geneve created a variety of very notable and collectible watches, they are most known for their esteemed chronographs, and of those chronographs, the Tri-Compax stands out as being their most recognizable model. The Tri-Compax was created in 1944 in celebration of the company's 50th anniversary, as was introduced as the new flagship mainstay for Universal Geneve. Featuring not only a full three-register chronograph, but the Tri-Compax also impressively houses both a triple calendar and moon phase complications into a relatively compact design. It's the blend between the mechanically complex design melded with a sophisticated dial presentation that has made the Tri-Compax so beloved and cherished by collectors today.

DIAL & HANDS The original, impressively well-preserved, and beautiful Tri-Compax dial features an unmatched vintage aesthetic and color palette.

Historical context

Golden Age of Mechanical Watchmaking (1900 – 1945)

The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.

The wristwatch overtook the pocket watch. Military use in the First World War, aviation, water-resistant cases (1926), automatic winding (1923–31), rectangular Art Deco designs and early chronographs and calendars defined the period.

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.
