Legendary Heuer Carrera chronograph powered by the excellent Valjoux 72 used in the 1960s and 70s by the best chronographs of the time, as well as the much more famous Daytona, which has nothing on this. This rare Carrera, ref. 2447T Red Tachy, made in 1965 (serial number 70XXX) is the first series with internal red tachymetric ring and two-tone dial on two levels. In very good overall condition despite being over 50 years old, with very small scratches that can be seen with the naked eye, perfectly coeval. The watch is in perfect working order and the great reliability of this calibre is one of the characteristics that sets it apart.
