Throughout the 1960s and 1970s Heuer complemented its main portfolio of celebrated chronographs with a number of different series of more affordable watches. Among them the 73321 is probably the most well known thanks to the number of attractive combinations it was offered in and its striking resemblance to the Carrera.

Debuted around 1968 and powered by the venerable Valjoux 7733, the reference 73321 was offered in a variety of configurations including pure silver, panda and reverse panda like the watch shown here. These models offer many of the attributes that make Heuer, and particularly the Carrera and Autavia lines so desirable, such as the strong design codes, excellent readability and robustness that a racing driver would demand, but often at a fraction of the price.

As a result they represent a perfect distillation of the iconic watches of the brand for those looking to take their first steps into the world of vintage racing chronographs.
