• Agate
• Sea shells
These items are too soft and may scratch during cleaning.
Welded or plated metal items.

Watches with lower water-
resistance ratings than
10 ATM/100 m.
• Remove thewatch strap from thewatch and wash thestrap in
thebasket if thewatch has alower rating than 10 ATM/100 m.
• In order to be able to use theincluded watch stand which
holds thewatch above thewater, thewatch casing must be
water resistant to at least 10 ATM/100 m.
• Theultrasonic waves might cause water to penetrate
thecasing of watches with lower water resistance despite
them being held above thesurface of thewater.
• Never immerse awatch in thewater tank of theappliance,
regardless of its water resistance rating.
• Make sure that theany buttons on thewatch are pushed in
