Be very careful not to wet the inside of the watch, as this could badly damage or even destroy it.
Place a dab of toothpaste onto a cotton ball or cleaning cloth, or even directly onto the dirty areas of the watch. Carefully rub the toothpaste over the spots, gently but firmly cleaning them. Start with the inside of the wristband. Then move to the outside of the band and finally, being especially careful not to reach the fragile inside, the gold-plated area of the watch itself. Finally, remove the toothpaste. Moisten a clean cloth or cotton ball and go over the watch, making sure to remove all the toothpaste. Any toothpaste left on the watch can cause corrosion, so make sure the watch is completely rinsed clean.
For this tactic, you can use just water, or toothpaste and then water. The bud may start to turn gray. This is the dirt and grime coming off the watch, and means you’re cleaning effectively.
