I have not translated the German, examined it carefully or written to the seller, but the one offered on ebay looks correct to me -- First Execution Screw-Back Case with Second Execution Dial. See the photos, linked below.

Here is what we say in the Autavia Section of OnTheDash --

Autavias with the first execution screw-back case utilized two different dials. The first execution dial featured large registers, luminous markers and the numeral "12" at 12:00 o'clock. The second execution dial featured smaller registers, thin applied markers and luminous dots to mark the hours (with double dots at 12:00 o'clock). The registers remained small in all future Autavias, so the first execution case / first execution dial is the only version of the Autavia with larger regsiters. All Autavias with the first execution screw-back case used dauphine hands.
