glued items
Watches:
Except diver's watches with

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 the cleaning is okay.
