LARGER than your 2254? Wow... I haven't seen the Oris Diver in person, but it looks smaller in pictures. I have never, however, seen a photo of the two side by side.
I tried this very watch on several months ago. this is a very nice watch.
the fit and finish was very nice. the watch was larger than my Omega 2254 and the case is different than I have ever seen before. thats about all I have, the black, and blue are very attractive watches..
