I got the one from Lelong (4+6) about a year back, very happy with it and bought another as a gift for a friend (2+3). However, because of my old Rolex, which is uni-directional winding, it does not wind sufficiently often as my power reserve will be spent after 2 weeks plus in the winder (of course, if I wear it, then it is ok). The other watches are ok so I think it is not "over-winding".
