Most certainly not over the ones they have used for 40 years or so, otherwise there would have been millions of reports of hairspring problems ..Over the many years the RWC now Rolex they have acquired quite a few patents like the twin lock crown system, and the automatic winding system but Rolex did improve that one most certainly.All these technical so called advances all sound great on paper,but until they get over the main problem with mechanical watches which is gravity.Afraid we are talking about perhaps a second or two with over all accuracy, and I am sure today know ones life depends on the absolute spot on second accuracy.As for getting magnetised still quite difficult even in todays electric gadget world,but some use it as a cope out for simple regulation, but its a very very easy job to de-magnetise if needed. But lets be very honest here for any mechanical watch to be at, or below COSC spec,is quite a feat of engineering, no matter whats in the case.
