You get what you pay for, I guess. I've been writing a lot lately, so I can't wear my watch (it interferes with the keyboard something fierce). The watch has been sitting in this automatic winder for three weeks now and the machine just keeps on spinning it, keeps on winding it, with no signs of slowing. I will say that there is a very, very slight noise involved now that wasn't there to begin with. It has most definitely gotten louder. But you'd have to expect that with such continuous use.
