As Jeff says below, the forum can be a bit quiet at this time of year - for most of Europe, it is the time of year when most people are on holiday.

It also depends a lot on who is around - I'm aware of having replied to a couple of similar queries to yours that were raised at the same time. And that's because one was about what was thought to be a Carrera, but was the economy equivalent and the other also about one of the economy watches. With my field of interest being the Carrera, it pays to know a fair bit about these economy watches as they have much in common with contemporary Carreras and it can be vital to know the differences.

Autavias, on the other hand, are much more of a closed book to me. Had I been able to add anything of interest or value to the discussion, then I would have done - but I am conscious that my Autavia knowledge is patchy and that there are people here who know a whole lot more about Autavias than I ever will.
