SPECIAL RECOMMENDATIONS

MAGNETIC FIELDS

Avoid leaving your watch near electromagnetic sources, as they may affect the operation of your timepiece.
CLEANING

Use a toothbrush and soapy water to clean metal bracelets and waterproof casings, then rinse with fresh water. Dry with a soft cloth.
SALT WATER

Always rinse your watch with fresh water after contact with salt water.
CHEMICALS

Avoid direct contact with solvents, detergents, perfume, cosmetics, etc., which could damage the bracelet, casing or seals.
WATER RESISTANCE

A watch's water resistant properties cannot be guaranteed indefinitely. They can be affected by seal wear or accidental shock. We recommend that you have your watch's water resistance tested once a year by an authorised Longines service centre.
SHOCKS

Avoid subjecting your watch to shocks, including sudden changes in temperature.
TEMPERATURE

Avoid exposing your watch to extreme temperatures (less than 0°C or 32°F and more than 60°C or 140°F) and sudden changes of temperature.
SCREW-DOWN CROWN

Before immersing your watch in water, make sure the crown is carefully screwed down to ensure no water enters the mechanism.
BASIC CROWN

Always push the crown back into the neutral position to ensure no water enters the mechanism.
CHRONOGRAPH PUSHERS

Do not operate the pushers under water, or water may enter the mechanism.
