Heuer Carrera

About this reference

The Heuer Carrera reference 3647N was produced during the 1960s, specifically between approximately 1963 and 1970. Collectors prioritize this reference for its minimalist two-register layout and the manual-wind Valjoux 92 movement, which utilizes a column-wheel mechanism. The "N" designation signifies a black (noir) dial, which is rarer than the silver 3647S variant. The 35mm stainless steel case features the signature sharp, faceted lugs designed by Jack Heuer to improve legibility and durability. On the secondary market, prices typically range from $8,000 to $15,000 depending on the presence of the original "Sunray" dial finish and the condition of the tritium luminous plots. A notable production detail is the transition from early dials featuring only the Heuer shield to later versions that include the "Carrera" name, with the early "unnamed" dials often commanding a premium at auction.
