It could just be the battery, which I know is replaceable, and I will get around to it soon, but I ordered what I thought was a "good quality" Fossil watch.  I love Fossil, love the look of the watch, but from day one of receiving it, it stops and starts when it wants to.  It's a little irritating to have to change the time on a brand new watch all day long. The fashion and look of the watch is just what I wanted though, so I'm keeping it.  Like I said, I will get around to replacing the battery soon and give that a try to fix the problem.
