Properly close the back of your Fossil watch so you can wear it again. You may have had to remove the backing to replace the watch's battery. Putting it back on is something you can do yourself, without having to pay a watch repairman. Being too forceful with the backing can result in a broken or damaged watch. Some Fossil watches have a snap-on backing, while others have a screw-on backing. With either type, be gentle when replacing the backing to avoid scratching the face of the watch.

Snap-On Backings

Turn the watch over, and align the backing over the watch's opening. Some watch backings feature a notch inside the case that must be aligned with a stem on the inside of the watch.

Lay the face of the watch on a flat, smooth surface. You may want to lay it on a clean towel, to avoid the face getting scratched.

Press down on the watch backing with both your thumbs. Keep applying enough pressure until you hear a snap.

Screw-On Backings

Lay the watch facedown on a flat surface, on top of a clean cloth to avoid scratches.

Align the backing over the watch's opening. Using a pair of tweezers, place the screws inside the holes.

Turn each screw clockwise until tight. Avoid over-tightening the screws, as this may cause them to become stripped. Repeat until all screws are tightened.
