Garmin Sports Watch Maintenance Guide: Any time your watch comes into contact with seawater or mud, please rinse it with clean water. For metal watch bands or resin watch bands with metal parts, use a soft-bristled toothbrush or similar tool dipped in a weak solution of water and mild neutral detergent or soapy water to wipe the watch band. Then rinse away any remaining detergent with water and wipe dry with a soft, absorbent cloth. When rinsing the watch strap, please wrap the watch case with plastic wrap so that it does not come into contact with detergent or soapy water. If it is a resin strap, rinse it with water and dry it with a soft cloth. Note that sometimes a stain-like pattern appears on the surface of a resin watch band. This has no effect on your skin or clothing. Wipe away the stain pattern with a cloth. Wipe with a soft cloth to remove water and sweat from the leather strap. Watch crowns, buttons, or rotatable slots that are not in use may cause future operating problems. Regularly rotate the crown and rotatable card slot and press the various buttons to keep them functioning properly.
