Catalogue description

Dealer description — S.Song Watches

The Heuer Autavia really needs no introduction. What was once seen as a cheap sports chronograph has, in the last 18 months become one of the hottest and most in-demand vintage watch in the market. The Autavia was released in 1962 under the new management of Jack Heuer, where the name was an amalgamation of the words ‘Automotive’ and ‘Aviation’. This was the first line that Jack Heuer released, even before the famed Carrera line, placing significance on the Autavia as the model that marked a new chapter for Heuer. In fact, we’ve seen the Heuer brand go from strength to strength, with the most recent event being the thematic ‘Heuer Parade’ auction held by Phillips in Geneva. Fresh off the sale, Heuers, in general, have entered a new era where collectors that are usually more inclined towards Daytonas and Pateks are turning their attention to the Heuer name as a legitimate blue-chip brand. This listing features an extremely rare, early variation of the Autavia and it is known to collectors as the Ref. 3646 ‘Second Execution’. In general, the earlier the Autavia, the rarer and more desirable it is. A few of the distinguishing factors of this Autavia include the style of the dial with the alternating hash marks and dauphine hands. On top of this, the watch is housed in a screw back case with long bevelled lugs as supposed to the later, more common compressor cases. This example is a later version of the ‘Second Execution’ series, denoted by the ’T’ on the dial, indicating that by then, Heuer had transitioned from radium to tritium for their luminous material. The Ref. 3646 Second Execution is a very attractive watch, with its classic reverse panda layout and elongated, bevelled lugs. A very easy watch to wear, it really does define the 60’s both in its styling and motorsport heritage.

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.
