Very Cheap DIY Kinetic Watch Winder

After buying my second Seiko Kinetic watch, i needed a way to charge it without shaking the crap out of it or spending $100 plus for a winder. After seeing others make winders, I made one even cheaper and much, much easier. Look at the picture and you can see how to make it. It is a crappy picture from my phone, sorry. Just used a pan head bolt with a wind nut on the underside to keep the carboard still. Place a mild rubberband around trigger and voila, easy and damn near free. You have to gauge the speed and not spin too fast or it won't wind.
