perhaps a mute point but..
my noob LV stopped once (asian) and i shaked and tapped and freaked out. nothing. completely dead.
i opened the crown and whatnot and it started ticking then stopped again once i had screwed the crown in.
i realized that if i twisted the crown in too tight, it would jam up the movement.
solved my problem.
guess its the risk you take buying an asian. if i know its a watch im going to cherish, i spring for the eta. its just worth it imo
