I had an older Seiko self winding watch that I bought in Saigon in 1965 during my time in the war. It is a good watch but I wore in infrequently because it was always run down from the lack of movement of the self winding mechanism. Most of the winders I found in stores were a great deal more expensive than the watch itself had been. I found this one on Overstock.com and the price was right. The winder is great - it was relatively inexpensive and it works exactly as desired. My watch is always ready for wear. No more having to try to remember how to set the day and date feature before each wearing. Thanks Overstock.com!
