! CAUTION
Always keep your watch clean
Small amounts of dirt may become trapped in the tiny gap between the
crown and case making it difficult to pull out the crown. It is recommended
to occasionally turn the crown in its normal position to remove any dirt.
The case and band of the watch come into direct contact with the skin in
the same manner as undergarments. Corrosion of the metal or unnoticed
soiling such as that caused by perspiration and dirt can soil sleeves and
other portions of clothing.
Wearing this watch may cause itching or rash if you have sensitive skin or
certain physical conditions. If you think there is something wrong
discontinue wearing the watch immediately and consult your physician.
Possible causes of rashes include:
1. Allergy to certain metals or leather.
2. Rust, dirt or perspiration present on the watch's body or band.
Leather bands may become discoloured by perspiration or dirt. Always
keep your leather band clean by wiping with a dry cloth.
Do NOT wear the band too tightly. Try to leave enough space between the
band and your skin to allow adequate ventilation.
