Rolex 4030 Vs. 4130

I am kind of getting interested in Daytona's and thinking of adding a gen to the collection. I wanted to have the experts weigh in as I know nothing of these movements other than both are supposed to be two of the finest chronograph movements ever. Can anyone give me the technical pros and cons for these? The Zigmeister? Thanks in advance.

Thanks, yes I am aware of the transistion and the brief history. I'm wondering more about technical stuff, like rotor bearings & assembly, clutch, etc. Was the 4030 a column wheel design? That kind of stuff.

Actually, I think both are column wheel designs and maybe someone could tell us why a column wheel chronograph is considered "higher grade" than a cam/lever design like the 7750.

AFAIK, the 4130 they built themselves while the 4030 was a modified El Premeiro movement. Not anything "wrong" w/ the 4030, I'm sure the pride of producing your own in-house movements finally got the best of them.
