7733 Carrea on Ebay

here's a question for all, there's an auto type case Carrera with 7733 movement up for sale on ebay.

now the catalogues show only silver or blue/gray dials, yet this one has a black dial that looks genuine Heuer.

is it a dial taken from the last of the old style Carreras and put on to replace a damaged original dial or did they ever make them like this?
