Footnotes:
The Heuer Autavia model was first introduced in 1962, the name deriving from a combination of 'AUTomobile' and 'AVIAtion'.

The 2446 is commonly nicknamed after the Austrian Formula 1 driver, Jochen Rindt (18 April 1942 – 5 September 1970) who famously was known for his daring driving and passion for the sport. Whilst practicing for the 1970 Italian Grand Prix he lost control of his Lotus 72 and unexpectedly hit the guardrail with fatal consequences. Despite there being 4 more races to complete, Rindts competitors of the day were unable to score more points and he remains the only Formula 1 driver to posthumously be awarded World Champion.
