This. Watch snobs might balk at this newest "fad" but they are by far in the minority.
I might not go in to an important meeting wearing the bright green sport band but a leather band, milanese loop or link band would be more than enough to appear professional. Although... If your skill set & abilities are above par then you shouldn't have to worry about "will my watch be ok" when heading in to any business meeting, regardless of the band or whatnot.
