I have Mark II Orange - loving it as this watch are exemplary reissue.
My commments on Mark II is The dial is nearly a stroke-for-stroke remake from previous version, what's attract me as always the key features : - SuperLuminNova, Double coated anti reflect glass, upsize 1mm from 41.5mm to 42.5mm, Powered by In-House/ETA Hybrid and last but not least COSC.
At Baselworld in 2014, Omega reissued the Mark II, and today we look at the gray and orange “racing dial” version. They are coming out the Olympic 2016 Rio version . Its available in Omega KL Boutique with no very limited discount.
