I found this on a website forum: Your Fossil Watches has four push button and one for winding button. the first button has mark of LIGHT , the below button is MODE ,,upper right START/STOP,,, lower is LAP/RESET. the center button is what they called it a CROWN to set crown is just pull it and you can set the hour and minute. the LIGHT button is the set button also, just press it for 15 seconds if dial flashes, then go to MODE button and choose what going to set, the START/STOP—LAP/RESET is the scroll button you going up and down the number or on /off ,some model of chronograph the set is in the MODE button just press it long and if flashes it ok. and follow procedure what i said before. setting cannot damage the watch… That help? The Fossil website is down right now, that’s the best I got. :)
