i have a Coke 16710 GMT II from 1989. Beautiful watch but I donít wear it very often so Iím donít really know itís . I wore it the other day and when I went to wind it I thought it felt odd. The crown is somewhat hard to spin and will actually rotate backwards when I let go of it when Iím winding it. It is keeping perfect time and the other two positions feel normal wherever Iím setting the time/date. So Iím just trying to find out if this is normal behavior. I havenít let it run down again so maybe itís fully wound but I think it was tight when I first wound it. It almost feels like Iím winding a rubber band. My Panerai does something similar and will basically snap back when fully wound but none of my other watches feel/act like this.
