Catalogue description
Dealer description — S.Song Watches
The Heuer Carrera would have to be one of the most iconic timepieces ever created. Designed by Jack Heuer in the early ’60s, the Carrera line still exists till this day with early models becoming some of the most desired vintage watches in the market. With the Carrera, legibility underpinned all of its design cues, with Jack Heuer taking an obsessive stance on stripping away all that was unnecessary and presenting only the most important information on the watch dial. The result was a clean three register chronograph with baton markers and an outer tension ring that featured the minute markers. Over the years, the Carrera saw many dial variants, from different color combinations to different scales featured on the dial. The example you see here today is a dual sub-dial Ref. 3647T, with the T standing for Tachymeter. The Tachymeter is displayed in red, contrasting well with the silver dial and this variant is one of the rarer Carrera variants out there. Powered by a Valjoux 92 movement, it's a column-wheel calibre that is both reliable and high in quality. Of all the watches ever created, in my opinion, the Carrera is one of the most beautiful and timeless. The case of the Carrera, with those long angular inward lugs, has an amazing proportionality and while it does look good in photos, on the wrist it is so much better. Even by today's standards, the Carrera still looks like a modern watch. It shows that in design if you only design what is necessary, without superfluousness, you will end up with a product that will remain relevant for generations.

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.

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.
