I bought this watch winder despite the negative comments and I am happy I did. The unit runs virtually silent and keeps my wife's watch always on time. There is an adapter for larger watches and the built-in timer keeps things going without input. Although there is no option to make the unit reverse motion, for the price, I have no complaints. (Have you seen the price of a wolf design winder). Admittedly,the finish of the unit is not of the highest quality, but it does what it is suppose to and I recommend this unit.
