I am a little late adding to this post but I just saw it last night. Here is my 2446C which I bought from the Son of the original owner. His Dad was an F105 pilot in Vietnam. I believe it is all correct accept the sub second and hour counter hands which I changed later.

: Team:

: I am in the process of overhauling / updating the Autavia section
: of OnTheDash, and tonight I worked on the 2446C GMTs.

: I have reorganized the section into four executions, as follows:
: plain polished steel hands and pushers, with white chrono second
: hand plain hands and pushers, with red chrono second hand plain
: hands, red chrono second hand and fluted pushers brushed steel
: hands, with red inserts and tips

: You can see the updated section, here --

: It would be great if readers can post photos of these Autavia GMTs,
: or you can send them to me privately. As always, serial numbers
: will be appreciated (and may help sort out the executions).

: Thanks in advance for your contributions.
