Autavia 2446 3rd Exec.

The 3rd execution Autavia was launched with a new case and dial in 1968. The screw back case features a thinner bezel than the first screw back case and the dial is simplified with steel hour markers and plain steel baton hands (same as the Transitional). The lugs with a bevelled edge take the 19mm HL ends (H for Heuer) on the Gay Freres bracelet. Valjoux 72 movement and caseback signed Heuer Leonidas.
