Well, it's a bit of give n take really.

The 'V' stamped on the case is seen right across the lifetime of the Autavias, I have 1163s, 11630, and even 1063s with 'V' after the numvers on the case, no one knows why it's there. (AFAIK), maybe it means 'variant', who knows.

That's why I feel OK about dropping the V from any description. So, I would have no problem about dropping the V. Image that Siffert never wore a Heuer, or that the Viceroy promotion never existed...

They would be described as:
1163T White dial + black registers
1163T Black dial + white registers

Simple. I think that there might be a bit of protectionism amongst Siffert owners, that has seen the white dial claim the 1163T moniker, it's an easy way to distinguish between the highly valuable 'Siffert' and the 'Viceroy'. In my mind, they are both 1163T's, just with different colourways.

: Thanks Stewart,

: Is it correct to refer to a viceroy (or any other 1163 case autavia
: that has a tachy bezel) as an 1163T - or is that reserved as a
: special designation for the jo siffert variant?

: i assume the answer is yes. i would think it would be illogical to
: suggest that ONLY the sifferrt can be called an 1163T
