Originally introduced in 1964, the Carrera is easily one of the most iconic chronographs under the Heuer brand. The watch at hand is reference 1153 with caliber 12 automatic chronograph movement, which has a hidden microrotor. A direct decedent of Calibre 11, one of the first ever automatic chronograph movements, this Calibre 12 is a workhorse with fine pedigree. The charcoal grey panda dial has a hint of natural patina and a striking orange seconds hand. please take note of the reset chronograph pusher as it has been replaced with a generic one. This watch runs and keeps times but is being sold As Is, as we have not serviced it. Box and papers are not included.
