Looks like a Zenith Open Defy stealth model. I've seen some reps in gold/black but none in red. A lot of folks don't know this by looking a the pics, but the large red helix gear on the left doesn't actually spin. It's part of the shock transfer system of the watch.....the model is supposed to be relatively "shock proof", and that large red helix gear looking thing onthe left is supposed to separate and disperse energy absorbed by any shock of hitting the side of the watch. Pretty cool, but it's a beast. I tried a gen on at a watch shop in the Galleria, and it is a massive one.
