I am inclined to go with Mark,the speedmaster was my first thought (perhaps a nice 70S Mk.II ?),then I remembered this one..

(I couldn`t find any other pics in a hurry,so I snipped a few off Heuerboy,hope you don`t mind Nic.)
PVD blackness with red contrasts,lovely.The "quattro" marking is actually printed underneath the crystal,cool detail.
The perfect "zubehor" if you have one of these:

: Hodinkee, one of the most prolific and interesting watch
: bloggers, has asked the question, "What are your favorite
: auto-inspired timepieces?".

: Assuming that he has the complete list of the Heuers (Carrera,
: Monza, Monaco, Autavia, Camaro, etc.), please post a message
: here to tell us about your favorite "auto
: inspired" timepiece, that is not a Heuer. Note
: that he uses the word "inspired", so it does not have
: to be a watch that is named after a track, race or racer . . .
: anything inspired by an automobile. He also uses the word
: "timepieces", so perhaps it can be a stopwatch, clock,
: etc.
