Watches have shiny glass surfaces that are prone to develop scratches with regular use. No matter how careful you are, getting a scratch on your watch face is bound to happen sooner or later. A scratched face not only takes away from the overall look of the watch, but also reduces its value. You may get rid of moderate scratch marks from a watch face by using common household products, including toothpaste.
Prepare a work area. Place the watch on a level surface at a comfortable working height, facing a light source such as a lamp. You will be able to see all the scratches clearly, as the light reflects off the glass surface.
Apply toothpaste on the scratched areas. Note that gel will not work in getting rid of the scratches; only use regular toothpaste with normal consistency. Place the watch directly under the light and squeeze a small amount of paste to cover the scratch.
Rub the toothpaste on the surface. Use a finger to flatten and rub the paste over the surface, going in a smooth, circular motion. Apply more paste if there is more than one scratched area, and rub it in.
Let the paste stand. After flattening the paste over the scratch, wait for a minute so that the paste can settle and "soften" the scratch. Remove any excess paste from the surface or around the edges of the face, to prevent it damaging internal components by seeping inside the watch.
Wipe off the toothpaste with a soft, non-abrasive cloth, after the paste has been allowed to settle for about a minute. Wrap a small piece of cloth around your finger and gently start wiping the paste off the surface.
Hold the watch face to the light and check for any scratches you may have missed. You may have to repeat the procedure for stubborn or deep scratches. In some cases, you may not be able to remove the scratch completely, especially if it is too deep. Although rubbing with toothpaste may not eliminate a deep scratch completely, it will make the scratch look less obvious.
