This vintage, steel Heuer Carrera 3647N watch from the late 1960s is a beautiful example of a now iconic racing chronograph. It has its original, two-register black dial with tritium hour markers and hands. It also has its original, Heuer signed crown.

The Heuer Carrera 3647N epitomises?the brand's famous sixties spirit and design philosophy. Jack heuers strict adherence to legibility and function, ahead of all other considerations, accomplished a design classic that arguably represents his vision in its purest form. The Heuer Carrera was available in two or three-register layouts; with this 3647N example featuring the former. The N stands for noir, denoting its all-black dial. This example is one of the later models produced, as evidenced by its signed crown and T-Swiss dial.

Like many of Heuers most iconic chronographs, the origins of the Carrera can be traced back to 60s motorsport. It was inspired by?one of historys most dangerous events, the Carrera Panamericana,?the legendary border-to-border sedan and sports car racing of the 1950s, on the open roads of Mexico. Translated to "race" or "career" in Spanish, the event ran for five consecutive years and was entered by racers from all over the world, representing virtually every motor sport. Taking inspiration from this, Heuer chronograph wristwatches throughout the 1960s and 70s were often the tool of choice for professional racecar drivers, owing much to Jack Heuers appreciation for motorsport, and hands-on approach with its teams and drivers.

This Heuer Carrera 3647N has a T Swiss dial. The hour markers are applied, together with aged tritium index markings. The Carrera 3647N also features a clear, outer-track, with 1/5 second demarcations on the tension-ring. The crown of the watch is correct and bears the standard Heuer signature, along with corresponding original pump pushers.

The watch carries the manual-winding, 17 jewel, Valjoux Calibre 92 (labeled as "Leonidas") at its heart, beating at 18,000 A/h, with a power reserve of approximately 39 hours.

This Heuer Carrera 3647N comes fitted with a black leather rally strap and Heuer steel buckle.
