Watches:
Except diver’s watches with depth

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

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.
