Fossil has been a leading producer of fashionable-yet-affordable watches since the 1980s. Fossil watch cases are pressure-sealed to make them water-resistant. This often useful feature can present a challenge when it comes time to replace your watch battery. Removing the watch back with a watch case opening tool is only half the battle. Luckily, replacing the back of your Fossil watch is a lot easier than getting it open.
Hold the Fossil watch face down in the palm of your hand.
Line up the notches on the back of the watch with the indentations on the watch's inside rim.
Apply gentle pressure to the center of the Fossil watch back to snap it into place. If the back of the watch does not immediately snap into place, gradually apply more pressure until it does.
