Jeff,
I study a lot these orange Autavias.

In my opinion serial range si around 240xxx.
First got orange stripes hands, the last used metallic orange hands as your watch, Museum Orange Boy and my 1163P.
So, after 242xxx, we can find 11630 style hands on 1163 orange boy or white orange boy.
For the dial, white one is in line with 1163 last production in all details.

Jeff, here's 2 samples of Autavias 1163 with your hands, serial243xxx, original in all details!

This is my 1163P with all orange hands

and this is Alberto Museum 1163 Orange Boy

So, I can't accept that these watches are not original...

I respect Alex, but in his website he says that there's no "step design" caseback on 11630: this opinion is not correct on the first cases and on a great numbers of GMT 11630!
From his website:
. The case back should always look "dome style", WITHOUT having a single step break around the side line of the case back cover. If the case back is with single step, than ask for a discount as than you deal with a 1163 back cover on a 11630 case (if the case has the 11630 engraved).

So I think vintage Heuer chronographs are a big mistery for all, expecially in transitional period for some watches like Autavias!

Be shure, my friend: your watch is right in all!

: Here is a comment that Alex posted on Facebook. i have seen
: about 2-3 white dial 11630 and compared the dial carefully with
: the dials of the 15630 and 1563 silver dial. My opinion was
: always that the markers being with black lines around the lume
: line belong to the 1563 series whilst the markers having orange
: side lines to the lume belong to the 15630 series: It always
: fits: I mean there are only very very few 15630 silver dial on
: the market: not more than 4 and all have the orange side lines.
: Also this fits with all the black 15630: so orange outside lines
: around the lume. I never checked this with a e.g. 11630 silver
: dial as well as a 11630 white dial: but did today: I still have
: NOS 11630 silver dials at home: all these dials have black lume
: lines around the lume (like the 1563!). Than I checked the 11630
: white dial I have (see above pic) and this has a completelly
: different picture: here we have no lume area (line) like
: discribed but we have lume dot plus a closy top line in black.
: Same as your two pictures of the 1163 white dial. All the 11630
: I have seen showed the same picture. In additional I strongly
: believe orange hands do exclusivelly belong to 11630 or 15630
: models. All 1163 models should wear either steel hands , steel
: hands with black/dark blue insert or viceroy hands: like the
: 1163 vic, the siffert or the orange boy. So I believe the 1163
: cream with orange hands should be a 11630 white dial (and has
: thus a wrong case!) and only the one with vic hands orange might
: be a 1163 cream. For me its magic still that both watch types
: carry the same lume pattern: this is unusual especiayll a we can
: assume that these two watches: white dial 1163 and 11630 are not
: made in the same years. I am not an expert in the 11630s,
: but will address the question that he raises about the 1163
: "Milk Chocolate" Autavia, when time permits.

: One thing that I am very confident about -- this dial and these
: hands have aged together . . . the tone of the orange on the
: hands and the orange "stripes" on the registers are
: identical. Just because we have not seen an identical sample
: previously does not mean that it is not authentic.
