I've got a good comparison photo at home next to an Autavia and Carrera, I'll post it in an hour or so.

: About the same as the Carrera 1153 you tried the other week David,
: 38-9mm, but I find the integral bracelet makes it wear a shade
: smaller. It's mildly ovate, I wouldn't go as far as to call it
: actually oval - sort of between the 1153 and the barrel.

: Very nice effect on the dials, I think you'd like that bit.
