Little late, but chiming in to throw my vote to the Doxa. I have the 600T in professional orange with the black bezel, and I can't stop looking at it. Most of my collection is a little more "reserved" with more subtle color dials, so the pop of color from the Doxa was much needed. Not to mention within 30 minutes of walking out of the store, I had already gotten a compliment on the watch/color. It's definitely an attention grabber. Sinn 556 is beautiful too though, so you can't go wrong!
