Split the bracelet at the clasp so it's out of the way. Keep the watch held face down, if you have a holder then so much the better, but you really need to hold the watch head firmly. Then use a tweezer style tool to press down and pinch both sides of the bars. Keep pressing down on the bar as you pinch it together and move it away from the watch head. If you don't put enough downward pressure on it, the tool will slip off the spring bar.
