What is the difference between the model 590 Quartz(Battery Powered, and the 490 Mechanical(Manual Wind)? Basically what I'm asking, is, what is the difference between a Quartz Battery Powered watch, and a Mechanical Manual Wind watch.
The watches can be seen here: Stocker & Yale
They are the two watches at the bottom left corner of the page.
Thanks!
Jeff
