These items are not hard, so scratches may occur during
cleaning.
Ultrasonic cleaning may enlarge the gaps inside the welded
joints, plated coating or glued items and may cause
separation.
Because the strong penetration capability of the ultrasonic
waves, water may get into the watches if they are not truly
waterproof. Use the watch stand supplied as a precaution
if not sure.
Ultrasonic cleaning may enlarge the cracks pre-existed in
the coating on the glasses, ceramic, and glass. If the items
have no pre-existing cracks, then it is okay.
