I have this watch winder for 1 week now in use and it works very well. My watches run without any problems since. However, quite silently, he is not, but usually does not interfere in the bedroom itself. Unless you have a restless night, wakes up at night and want to fall asleep again, as happened to me yesterday. ;-) Then suddenly one that device appears suddenly ultra loud and disturbing. That's why I now would rather put it in my study. I would buy it again.
