Three Versions of the "Siffert" AutaviaThe Autavia Reference 1163T Chronomatic was the first Automatic Autavia, being introduced to the public in March 1969. This white-dialed Autavia is known as the "Jo Siffert" Autavia, having been worn and promoted by Swiss Formula One star Jo Siffert.
- This first version had "Chronomatic" above the Heuer logo and "Autavia" above the date, as shown below.
- The next production model had "Autavia" above the Heuer logo, and "Automatic Chronograph" above the date, with the Chronomatic name being deleted. The polished hands continued from the first version; hour recorder has numbers 3-6-9-12.
- The final version had two changes: the hands were brushed steel, with blue tips, and the hour recorder has the numbers 1 through 12.
We refer to any of the Automatic Autavias with the white dial / black registers as a "Jo Siffert" model. Some say that the early Reference 1163T Chronomatic model is the only true "Jo Siffert" Autavia.
