·Exactly, that is my impression too. Hence the question to the forum. On David's Autavia referece, he also agrees.
That's not quite right either, as the watch Siffert wore was more likely an early version of the 1163 with a Calibre 11 (or maybe 11i)
Still, it's definitely the automatic Autavia, Cal. 11, 11i, or 12 with the white & blue dial that is the Siffert, not the manual-wind models. That hasn't stopped sellers of the manual-wind "Siffert color" Autavias from calling them Sifferts, nor has it prevented them from selling at higher values than the more common Derek Bell / Viceroy colors.
