Temperature Care

Avoid temperature extremes. Exposing your watch to high temperatures, such as placing it on a dashboard of a vehicle, or use in a hot tub, may cause the watch to malfunction, shorten battery life or damage certain components. Leaving the watch in extreme cold temperatures may cause irregular timekeeping until the watch returns to normal operating temperature.
Watch Cleaning

For maximum performance, you should wipe your watch with a clean soft cloth, regularly. Stains, water spots and accumulated dirt on the case, crystal and bank that are not removed may cause premature wear. If you use your watch in the shower, or in chlorinated or salt water, you should rinse it with fresh water and thoroughly dry it afterwards.
Care for Metal Bracelets

To extend the life and maintain the good appearance of a metal watch bracelet, the following are recommended:
• Be aware that since the watch and bracelet is worn next to the skin, it collects dust and perspiration and becomes soiled if not cleaned regularly. This is particularly true of the inner parts of the links or mesh of the bracelet.
• Soil and rust, when present in a bracelet, are dissolved by perspiration and can cause staining of cuffs and irritation of the skin in some instances.
• Heavy perspiration should be wiped off the watch and bracelet with a soft dry cloth. The bracelet should be cleaned occasionally by using a soft brush and warm soapy water after which the soap is thoroughly rinsed with clear water and the bracelet dried completely. The foregoing manner of cleaning should not be done if the watch is not water-resistant but should instead be done by your jeweler
Care for Straps
Leather:
• Heavy perspiration, if not removed from a leather strap, can wash out the natural oils and cause the leather to become dry and deteriorate. Any moisture should be blotted with a soft cloth or paper towel and the strap allowed to dry naturally.
• Salt residue and soil can be removed from the leather by cleaning with a dampened soft cloth and mild soap or saddle soap.
• Occasionally, the inside surface of the strap should be cleaned by using a soft cloth dampened with alcohol.
• The strap should always be worn a little loosely (one finger space between wrist and strap) to allow air to circulate thus allowing any moisture to evaporate.
Rubber:

• Rubber straps should be washed frequently with mild soap and warm water using a soft brush.
• Thorough cleaning, using the same method, should especially be done after use in salt water.
• Solvents, oils, perspiration, tanning lotion and salt can cause rubber to deteriorate if not removed
