As with eye-glass frames or accessories, skin irritation may result from metal ions from the metal parts of a watch being extracted by perspiration. This kind of reaction is categorized as allergic skin dermatitis, which is caused by metals such as nickel, cobalt or chrome. These metals are included not only in metal bands but also in leather straps (chrome is used for tanning).
If you experience allergic reaction, stop wearing the watch immediately and consult a dermatologist. With a doctor’s assistance, clarify which metal caused the allergic reaction, and try to avoid selecting products which contain this metal. For those who are allergic to nickel or hyper-sensitive to stainless steel, we recommend that you use a titanium watch. For information on Seiko products made of titanium, please contact an Authorized Seiko Service Center.
