Calling all Cal. 15 Autavia owners...

We see on various sites (OTD, FlickR etc), some of our Heuerista brothers photographs of black dial 15630's with orange accents on the hour batons.. like the photo below.
But , I can't find this model in catalogues. The 1563 - in catalogues this doesn't have orange on the batons, in fact, the example in the photo gallery on OTD has white hands, but in catalogues it has orange hands.

Can we explain this.. is the following correct or incorrect: (black dial only)

a. 1563 = Orange hands
b. 1563 = orange hands and orange batons
c. 15630 = orange hands & hour markers
d. 15630 - orange hands
e. 15630 = white hands

Catalogues show only A and D.

Cheers
Stewart
