Chopard Superfast 919 Jacky Ickx LE (03.05 Movt)

I just picked this one up from a trusted vendor and was hoping someone here might have some experience with the Superfasts with the 03.05 movements. I've been wearing it off and on for four days and it sems to be running and holding time like a champ. I am not familiar with these movements and would like to find out about some of the characteristics of the movement. It winds as smooth as any watch I've ever handled (really smoother) but the rotor is louder than any I own or remember hearing. I have no service history so do you think a service is in order even if running well? Has anyone come across any hands on reviews of the movement particularly the -m version?

One last thing, does Chopard offer any historical info on LE models? This one is a very low # out of 50 so previous ownership might be a kick to know!

Had it by the local AD in Boston today and they gave it the thumbs up! I would still like to find some info on reliability etc. All I've found are reviews of the way they look and feel when new.
