I received this watch winder today and put two of my automatic watches in it right away.  I really hope it keeps them wound; I love the size of it and it seams pretty quiet.  I selected setting "C" to wind the watches; it already appears to be working better than my old one - which is going in the trash.  I have a total of four automatic watches, and I am considering ordering another one of these.  Time will tell - no pun intended!  On the down side, this winder is not of the best quality - it feels cheap, but I don't expect too much for $69.  I don't really care about that though, I just want it to wind my watches!  Good luck with your decision.
