this is a Carrera 1153 in the very rare and sought after BN execution with blue dial and blue/black subdials. the allover condition of this vintage racingsport watch from the early 70s is spectacular. with an unpolished case (serial 303xxx) and a beautiful dial with original lume (also in the hands), this carrera is one you won´t find very soon again in this condition. all parts on it are full original heuer. the caliber 12 is in top condition and won´t be in a need for service soon. This vintage heuer will come on a blue leatherband by glc straps in rome, or, if you would prefer, on a black racing leatherstrap.
