Catalogue description
Dealer description — Craft & Tailored
From outer space, the racetrack, sailing, diving, and to the North Pole and back, Yema wristwatch’s were built to accompany adventurers from the get-go. Founded in 1948, the Yema wristwatch company saw early success and quickly became the best-selling French watch brand of the 1960s. The Yema Yachingraf was introduced in 1966 for the sole purpose of regatta racing and features a highly visible red, white, and blue countdown timer for the right sub-dial to track the 5-minute countdown at the start of the race. The Yachtingraf eventually became the official watch of the French Sailing Federation and went on to accompany the French National Sailing team in the 1972 Olympics. The Yema Yachtingraf ref. 9312 houses a Valjoux Cal. 7733 chronograph movement.

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.
