Catalogue description

Dealer description — S.Song Watches

The Gallet Multichron 30M, when first introduced in its early form at the start of the 1900s, was considered the first wrist-worn chronograph and also the first waterproof chronograph wristwatch. While this example is a later version, released around the 40’s its iconic ‘clamshell’ case retains these characteristics as a solid, high-quality watch, capable of withstanding tough conditions. The clamshell case is considered one of the most iconic case designs of the 20th century. Famous for its two part case, with its four screws on the backside of each lug, the patented design that was acquired by Gallet was meant to keep the watch waterproof and tight. Not surprisingly, it was developed prior to WWII, with the military in mind. As soldiers were often in adverse conditions, they needed a reliable timepiece and the clamshell case certainly stood up to the test. As it is quite a unique and recognisable design, any chronograph with the clamshell case today demands a premium on the market. Furthermore, the Gallet 30M has become especially well-known due to its distinctive looks, often incorporating multiple scales on the dial. This one has a telemeter and a tachymeter. With this specific example, it features the characteristic red print for the scales, contrasting beautifully with the dial that has developed a warm champagne tone. Flipping the watch over it is powered by the Venus 150 movement, a column wheel movement that Gallet used extensively due to its high quality. Additionally, this Gallet is housed in a much rarer clamshell case, most recognisable by its angular downturned lugs that are reminiscent of the muscular Spillman style case.

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.
