Anne Klein watches are moderately priced, designer timepieces that typically use a battery-powered quartz movement. Some watches feature an automatic mechanical movement. The movement is a spring or electronic mechanism that regulates the time. Owners with no experience in watch repair should not attempt to repair the movement if it is broken because of its complex construction. However, replacing a dead battery, which is the most common reason for an inoperative watch, and removing scratches from the crystal are jobs that require little time or skill to perform.
Use a watchmaker's small, precision screwdriver to remove the four screws that fasten the back plate to the Anne Klein watch case. Insert the screwdriver's head into the slots and rotate the screwdriver counterclockwise until each screw is free from the holes.
Insert a penknife blade between the back and case to pry off the back plate.
Remove the O-ring if the Anne Klein watch is equipped with one. It is a rubber gasket that keeps the watch water-resistant.
Use tweezers while wearing surgical cloves to remove the battery. The battery is small, round and silver. Pull the battery out of its metal holder with the tweezers. Wearing surgical gloves minimizes contamination of the electronic movement with body oils, dirt or moisture.
Grab the new battery with tweezers and place it in the holder. Insert a new O-ring into the shallow groove.
Place the backing plate on the case. Place the screws in the holes. Use the screwdriver to tighten each screw by rotating it clockwise. Start tightening one screw, then move to the opposite side of the case to tighten another. Move from one end of the case to the other, slightly tightening each screw until case and back are evenly tightened and snug.
Removing Crystal Scratches
Use masking tape to cover the case and back plate.
Apply a small amount of abrasive compound to the crystal, which is the sapphire crystal or mineral glass that covers the dial. Most household polishing pastes are appropriate to remove scratches from the crystal, including silverware polish. Toothpaste, which also has abrasive qualities, also works. For tough jobs, consider using a diamond paste available from a jeweler's supply shop or online.
Use a clean cloth to rub the compound into the crystal using a circular motion. Continue rubbing for up to 10 minutes. Wipe away the compound to inspect your progress. Continue another five minutes if necessary until scratches are gone.
