Re: Heuer Carrera 2447 with a high serial number

: Hello Mark,

: do you have an idea when (i.e. in which serial number range) the
: change from the first execution to the second execution dial and
: hands might have happened?

: Regards, Robert

Somewhere in the 90s, though it seems to have been a soft switchover, i.e. we still see some first execution watches after we start seeing second execution. That fits with the assembly model, so it's actually just what we would expect.
