It looks like I have another impending "big life event" in the next couple of months, so I picked this up as a potential "birth day watch" (i.e. a watch that witnessed your birth) Its a 2504.70 - 36mm with an MOP dial. The MOP is incredibly hard to capture, but this is the best I can do as of the moment. My understanding is that it had a limited run of 1000pcs. It comes in a bracelet, but I think that the dial is highlighted better with a dark brown strap Here is some other guy's much better shot of the dial: Depending on the angle and lighting, the dial shifts between a warm pearl color to a cool ice color. But the color runs very deep. Unlike the 2503.33 and 2502.33, aside from the fact that they do not have MOP dials, the indices are not blue.They are a black but reflects blue, much like blued steel
...that can squeeze out something big, different shades of brown/green and stinky, apparently up to 1.5m (so watch out!)
This is interesting. I have the 2503.33 and didn't realize the indices weren't actually blue. I have noticed that the flat edges of them and the Omega logo are a copper/goldish color.
