Third execution dial (smaller registers, with applied steel markers); polished steel hands, with luminous inserts; bezel is narrower than first execution screw-back Autavia and teeth of the bezel are cut on diagonals, rather than on perpendiculars

This model is identical to other second execution screw-back Autavias, with third execution dials, except that the numerals on the registers are rounded (derived from Helvetica)

This execution has fourth execution dial (rectangular lume markers)

This special order model has a Tachymeter scale printed on the dial, covering 50 to 200 units per hour; hands should be shorter than on standard models
