I have a vibrating watch.
People seem to consider this a sign of perversion. I don't really know why they dislike it. I don't strap it to my genitals or anything. It doesn't vibrate very long. Or hard, for that matter.
Although it's kind of cool to see people's expressions when I tell them I have a vibrating watch.
Personally, I got it because it was a cool gadget.
For the record: It's a ABC Championships Sports 50m Water Resistant Vibration Watch.
