How to Clean a White G-Shock G-7900A

Updated February 21, 2017

The G-Shock G7900A is a lightweight, shock-resistant and water-resistant timepiece designed for sports and outdoor use. As with other similar timepieces, the face of the G-Shock G7900A can collect dirt and oils from fingertips, and the bezel, bezel screws and white-resin wristband can quickly become dirty from exposure to dirt, sweat and clothing dyes. The key to cleaning the G-Shock is to use basic cleaning tools regularly to rub or brush away these accumulations and prevent permanent staining.

Dampen a lint-free microfiber cloth and gently rub the watch face, bezel and the slots of the 4 large grey bezel screws that attach the bezel to the front of the watch. If you can't remove all the dirt, apply a drop of mild liquid soap to the cloth, rub the cloth together to make it soapy and then rub the surfaces. Wipe away any soap with a water-dampened cloth.

Apply 2 drops of liquid soap to a fresh, damp cloth and wipe the white resin wristband to remove dirt, oils, sweat and dyes.

Scrub the slightly soapy surface gently with a damp toothbrush to remove stains. If necessary, apply whitening toothpaste or baking soda and scrub tough stains or rub the stain with a damp melamine resin foam eraser.

Wipe away soap and other residues from your watch with a damp cloth. When finished, wipe the watch dry with another cloth.

Tip

If can't remove all the stains from your G-Shock G7900A, apply rubbing alcohol to a cotton ball or swab and rub the stained area until the stain transfers to the cotton. Use additional cotton and alcohol as needed. If you still can't remove all the stains, contact Casio for additional assistance or to order a replacement band.

Warning

Harsh chemicals and abrasive cleaning tools can damage your G-Shock G7900A.
