you can play with diff options here, if you didnt already know.
http://www.breitling.com/en/models/aven ... /index.phpi would go with gold or brown. i owned a black dial colt chrono, had both and i thought both worked. i think a black strap would be... too black for my taste. as a wildcard option, i recall seeing grey croco strap on black dial here i think but i could be wrong. if youre not sure, i would play with cheaper aftermarket options to decide on a color, then order oem if that floats your boat. or just keep the aftermarket if that satisfies you.
i just ordered cognac(gold) croco from bj straps for my slate grey skyracer and hope to post pics and impressions once i get em. playing with straps is fun. i actually like my bracelet option the least. straps add so much more interest, to me that is.
