Human: What is the best way to clean a smudged watch? Assistant: 
The best way to clean a smudged watch is to use a soft, lint-free cloth and mild soapy water. Gently wipe away any residue with circular motions until the watch is clean. Avoid using too much water as this can cause the watch to rust or corrode. After cleaning, dry the watch thoroughly with a soft, lint-free cloth and avoid exposing it to direct sunlight for at least 24 hours.
