From the first day I started using it, it has kept PERFECT time just the way it was configured by the manufacturer, with no adjustment to the speed needed whatsoever. I don't wear my Rolex watch every day and reset it all the time was such a drag before getting this winder! I actually find I wear it more NOW than I ever did! This is because it is always at the correct time! It really has made me enjoy my watch so much more and really, what could be better than that?
