Heuer have many models nick-named after famous drivers including Mario Andretti, Jochen Rindt and Clay Regazzoni, but the most emblematic of all is probably that of the Swiss star Jo Siffert. Son of a dairy owner in Fribourg, Switzerland, Siffert quickly rose through the motorsport ranks racing motorcycles then formula junior before getting a break into F1. He then attracted the attention of Jack Heuer becoming one of the first brand ambassadors in the sense that we know it today, showing Jack’s pioneering attitude to promoting the products of brand, especially in the arms race that was the quest to create the first automatic chronograph.

The model offered here today is one of these famous Autavia Siffert models but what really distinguishes it is its sixth execution dial for which case numbers supposedly started from 223'000. This variation is noticeable by its blue accents made to match the blue chronograph hand. This blue on white colour combination enhanced on a steel Autavia tonneau-shaped masculine case undeniably reflects the car racing world and atmosphere from the 70’s.
