Heuer Carrera 45

About this reference

The Heuer Carrera 45 reference 3647 was produced from approximately 1963 through 1970. Collectors prioritize this reference for its minimalist two-register layout and the manual-wind Valjoux 92 movement, which utilizes a oscillating pinion design rather than the more common Valjoux 72 found in three-register models. The 36mm stainless steel case features the signature sharp, faceted lugs designed by Jack Heuer to maximize legibility and structural durability. Early examples are distinguished by "Ed Heuer" bridge stamps and "Swiss" only dials, while later iterations transitioned to "T Swiss" markings. On the secondary market, these watches typically trade between $5,000 and $9,000 depending on dial configuration and mechanical condition. A notable variant is the 3647T, which features a red tachymeter scale on the outer track, often commanding a premium over the standard silver or black "D" decimal dial versions due to its lower production volume.
