I have to say I take slight exception with the set up. For me there are three distinct eras. So distinct that they are incomparable with each other. The first being pre 1970. Pre 1970 I have to give it to Rolex on Bond alone….but also on their ad campaigns etc. The second era the 70’s and 80’s up to and through quartz. Also in favor of Rolex. The third era 90’s til today. Bond (which is not to be underestimated especially Craig Bond) not withstanding Omega has seized the crown (pun intended) in almost every way. Rolex makes great movements but Omega makes better ones. 15,000 gauss, silicon spring, Daniel’s escapement, better finish…the list goes on. Over all depth bragging rights. A diving chronograph that Rolex hasn’t even tried to match. I could have purchased any diver…I bought an Omega Seamaster because it a cut above. As far as I’m concerned Rolex has lost its diver supremacy to Seamaster (especially the PO line) and continues to improve with every new release.
