Ron indexes are also often a good indication especially on late Carreras..., not a must thought as often with Heuer, hence all steel meets all steel....

: Hello experts,

: While studying various manual Carrera, Autavia and Camaro models I
: noticed that some have been equipped with hands which have a
: black inlay. So far I have not been able to find the rule behind
: it. Is it related to the ones with a highly sporty look, like
: the ones with tachy scale or with tachy bezel?
: E.g. my Carrera 2447 NT has them.I also see them on the late manual
: Autavia with Tach bezel and red stopper. Or is this just a
: coincidence, and have they been used randomly.
: Thanks in advance for any input.

: Cheers
: Ron
