Autavia GMT information

I was able to remove the band to confirm the 2446C as well as the serial number 1963XX.

If anyone has any information on when it was made or other information based off the serial number I would very much appreciate it. Thank you.

According to On The Dash (http://www.onthedash.com/docs/Autavia_Reference_Table.htm) it has a Valjoux 724 movement and is from the 1970/71 catalogue. Check that link for more information.

I also made a quick video showing the Chronograph function.

Thank you everyone for all the replies and information. I think I have learned just about all I can about my fathers watch. It is an Autavia GMT reference 2446C Mk. IV, with a Valjoux 724 movement. Produced somewhere in the 1970-72’ range, original bracelet and configuration. Probably sold to my father around 73’ or 74’. It’s ties to the racing world are strong and that would be right in line with my father. Thank you again for all the information.
