The watch case and strap may discolour if they come into contact with mercury from
a broken thermometer or other equipment.
Keeping the watch clean
Use an absorbent soft cloth to clean off any dirt or damp from the watch glass.
Wearing the watch when the strap or back of the case is dirty can cause skin
irritation.
Cleaning the watch strap:
• Metal bands: use a toothbrush and soapy warm to wash the dirt off.
• Plastic or rubber straps: wash with water. Do not use solvents.
• Leather straps: gently rub the face of the strap using a soft dry cloth. Clean the
opposite side with a cloth and alcohol.
Periodic inspection
In order to guarantee long trouble-free operation, it is advisable to have the watch
checked by an Authorised Assistance Centre once every two years.
Keep batteries out of the reach of children
If a battery is accidentally swallowed, consult a doctor immediately
