The 2nd one for me, but on a bracelet. I like the look of the orange bezel of the first one but i am not sure how the rubber insert is gonna hold up
If it's your only watch the black. If you have other watches the black and orange without question. @meganfox17 has provided the appropriate imagery.
Orange is very old school Omega diver, looks vulgar and stands out like a sore thumb, but that's how a dive watch should be.
As per my profile pic Orange. Personally the orange pops but is not over the top. They are big divers your never wearing it as a dress watch anyway.
Nah, don't like orange at all. You'll be fed up with in on no time. Go for stylish black! And for the rest I fully agree with @dsio
I agree with Nobel Prize. If it's your only dive/sports watch, black. If you have one or more already, the orange and black would be a good variation in the rotation. Good with the matching orange band.
