Grand Seiko Spring Drive, should Rolex follow?

[No SUBctitute]

The great difficulty in creating a mechanical watch is making it extremely accurate. Its a difficult thing. (That's why watches that tick within a second or two a day consistently over years cost thousands of dollars.) Seiko replaced a very important part of a mechanical watch--the escapement--with a circuit. Interesting. But the accuracy no longer impresses me, at least no more than an accurate quartz watch would impress me--which is not much.
