Catalogue description

Dealer description — Craft & Tailored

Solvil et Titus, Or “Titus” as its commonly referred to as was once a premier watchmaking house in Switzerland. Titus was founded in 1887, but rose to popularity in the 1960s with their model the Calypsomatic as sports and diving watches were on the rise with the heightened interest in underwater exploration. Though the Calypsomatic is one of the lesser-known dive watches from this era, it's not at the fault of quality. Featuring beautiful gilt dials, interesting hand variations, and their notably large crowns, the Titus Calypsomatic are very much so collectible to the collectors in the know.

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.
