1): Omega cal.33xx has uni-directional winding.
2): Rolex 4130 is relatively new (2000). The
: earlier batch was a disaster. I doubt many
: watchmakers already got their hands on the
: 4130 because it's still very new (no need
: for service, yet).
3): As for El Primero, it's a very different thing:beat rate, power reserve. I can barely
relate El primero to 4130.

1)What is your source? A watchmaker? A magazine?False the 33xx is bidirectionnal winding
please see link, I was also told that by marco richon and daniel anselmi that I had the opportunity to encounter in Paris.
2) Not the case in the US, but I know some people who have their 4130 from year 2000 serviced in France through Rolex located on Rue Ruysdael and through my watchmaker (a former rolex watchmaker with +15 years of experience)and I also know some friends of my uncle who got their 4130 from the year 2000 serviced in Rolex Geneva. I got feedback from Rolex France as well as from my watchmaker and I think it is enough.
3) It is a self winding column wheel chrono movement even if it has a diffrent bph and power reserve I don't think it is important. Rolex modified the ep into the 4030 for maximum reliability and more ease to service therefore rolex is better. Rolex is better by the robustness, ease of service and power reserve being the biggest available on a selfwinding chronograph .
