A lot of times when talking about movements, I see people talking about hacking and hand-winding being a sign of a higher quality movement. Particularly with the seiko monster, a lot of people were waiting for a hacking/hand-winding movement. With my automatics, I just give them a little shake and they run for as long as I wear them, why the need for hand-winding? Also to a lesser extent hacking, although I could see if you wanted to be as accurate as possible even though you might lose/gain a few seconds a day. But hand-winding, how come it's so popular on automatics?
