Hi BHK9,
There are some very efficient automatic winding mechanisms out there, but none of them to my knowledge defy the laws of physics. It's not possible for an automatic winding mechanism to fully charge a 60 hour power reserve after only 10-20 minutes on the wrist unless you're doing jumping-jacks the whole time.

SJX, I really dont know.By the guess from the the only that's yours feedback,i guess there should be draw-back to this watch. Personnally,i handled the watch last week,well everything seems alrite! The rotor at the back, you mentioned copying the old watc...
John!Check this out!

Hi John, Me,neither a professor or physicist genuis but got little knowledge of the mechanism of 7037. This winding mechanism was a vast improvement of Perrelets's first perpetual wnding mechanism.This improve system ,the mass that charged the main spring...
