New Mark II Co-Axial thoroughly ¡¡ http://eluniversodelreloj.com/omega-speedmaster-mark-ii-327-10-43-50-01-001/
I love my Rio edition overall. EVERY Omega needs the clasp from this. I had to bail out on a Speedmaster 9300Ti, because I could not get the bracelet to fit properly. Here is my Rio. Camera angle makes it look huge. It actually fits nicely on my 7" wrist. All be it, the watch is a bit tall. The only thing I would change would be a thinner case.
Ditto loving the Rio one. I tried it on and it was VERY tempting! I was surprised how nicely it came together, nothing too gimmicky, very elegant.
