Relic is a line under the Fossil brand of watches. Relic timepieces are affordable and stylish, offering varying degrees of water resistance. Any Relic watch -- and most watches in general -- are fitted with a pressure-sealed, screw-down back to keep out moisture. Replacing the back of one of these watches after a servicing or battery change is relatively straightforward; but the right tools and process must be used in order to prevent moisture incursion.

Caseback Removal

Step 1

Lay the Relic watch crystal-side down on a firm yet soft work surface. A rubber mousepad is useful for this in a pinch.

Step 2

Adjust the caseback tool's teeth to align with the notches on the caseback.

Step 3

Turn the tool counterclockwise to free the caseback from the watch. Unscrew it the rest of the way by hand and set it aside.


Step 1

Keep the Relic watch crystal-side down on your work surface.

Step 2

Align the new caseback's threads with the threads on the back of the Relic watch.

Step 3

Turn the caseback down by hand, feeling for any grabbing or resistance. If you feel this, unscrew the back and re-seat it. Cross threading a caseback is a sure way to guarantee moisture entry.

Step 4

Adjust the caseback tool so the teeth fit the notches on the caseback.

Step 5

Set the tool into the notches. Turn the tool 1/4 to 1/2 turn to fully seat the caseback. Do not over tighten, as this can deform the waterproofing seal inside the lip of the caseback.
