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