to my eye, the Verona looks like a fatter version of the Carrera. case has the same traditional shape / lugs . . . it's just deeper, to accomodate the Cal 12 movement.
Most days, I prefer the Autavia to the Carrera, so maybe a vintage Autavia would fit the bill. It's definitely larger than the Jack Heuer Carrera, but keeps the traditional lay-out of the dial)as compared to the Lemania 5100-powered Heuers. The 70's era Autavias (like the two "Sifferts" shown below) will be larger in every dimension; the manual-wind Autavias will be about the same thickness as the Carrera, but the rotating bezel will give it more diameter.
Here is the recommended game-plan. Exchange the Jack Heuer Carrera for the Autavia re-issue. If you enjoy the re-issue Autavia, then consider moving into the vinatge Autavias.
Please keep us informed of your progress.
