• Magnetic fields: avoid putting your watch on a loudspeaker or on a refrigerator because these machines create magnetic fields that may damage it.
• Salt-water: always rinse your watch in fresh water after swimming in the sea.
• Shocks: avoid subjecting your watch to shocks, including sudden changes in temperature.
• Screw-in crown: always make sure you have screwed the crown in fully to avoid any humidity getting into the mechanism.
• Push-in crown: always push the crown back in to the neutral position to avoid any humidity getting into the mechanism.
• Cleaning: use a toothbrush and soapy water to clean metal bracelets and water resistant cases and a soft cloth to dry off afterwards.
• Chemical products: avoid all direct contact with solvents, detergents, perfume, cosmetics, etc. which may damage the bracelet or strap, the case or the seals.
• Temperatures: avoid exposing your watch to extreme temperatures (over 60 ° C or 140 ° F and under 0 ° C or 32 ° F) and to sudden fluctuations in temperature.
• Water-resistance: we cannot guarantee that your watch will be permanently water resistant. The seal may be affected by wear or by an accidental shock to the crown.
As recommended in our service instructions, you should have the water-resistant seals of your watch tested once a year by an approved Longines agent.
• Chronograph push-pieces: do not adjust the pushpieces under water as this may allow humidity to get into the mechanism.
