I have a Fossil Blue BQ-8774. To remove the watch back cover, I unscrewed the entire cover. There are notches in the back cover, and I used a small screwdriver in one of the notches and tapped it repeatedly, opening the back cover in a counter-clockwise direction. The battery inside was a 373, also known as SR916SW.
