How can a $100, hand wind Stuhrling watch, keep better time than a $1000 automatic Hamilton watch ? The Hamilton watch loses about one minute a day while the Stuhrling watch keeps accurate time. I guess it is not about keeping accurate time, otherwise everyone would buy a quartz watch ? I have an automatic, quartz and hand wind. Out of the three, as I said, my most expensive being the automatic Hamilton , keeps the worst time.
