I can't tell you anything about it's operation since I packed it right back up & sent it back.  My ladies Rolex wouldn't even fit on the watch holder when fully depressed.  I even tried unclasping the watch but it wouldn't clasp around the holder.  To my way of thinking,  a watch winder is worthless if your watch won't fit on it. So beware -  The holder is just too big for some watches.
