How often should you service your watch?

Check water resistance every 2 years (every year if in frequent contact with water) Servicing every 4 to 5 years

  • Water resistance

    Your watch's water resistance features are engraved on the case back next to the fish marking.

    This water resistance marking indicates the depth to which the movement is protected from dust, moisture, and any damage that may occur if it is submerged at that depth. Seals are used to make watches water resistant. To ensure continuous water resistance, we recommend replacing the seals every two years from the date of first use. It is also advisable to have our experts test your watch's water resistance every year if it has been exposed to seawater or pool water for long periods. Never adjust the crown while submerged in water because it may leak into the case. It is best to remove your watch before taking a shower or bath and before entering a sauna or steam room because heat, soap and steam can prematurely age the water resistant seals.

    Condensation under the crystal indicates that water has got into the watch and it must be checked as soon as possible.

  • The movement

    In quartz movement watches, the movement is powered by a battery than can last for 2-4 years, depending on the model. If the battery is completely discharged or low (the centre second hand on some watches will begin jumping ahead four seconds), we recommend taking it to our expert watchmakers without delay. Never leave a flat battery in your watch. It can leak and permanently damage the movement.

    Important: It is best not to adjust the date between 10:00 PM and 1:00 AM.

  • The strap

    If your watch has a leather strap, do not get your leather strap wet to avoid damaging it. We recommend replacing your strap every 2-4 years depending on how often it is used. Use only a clean and dry soft cloth to clean your strap. Do not use chemicals like soap, alcohol or solvents. Avoid contact with water.

    Before cleaning ceramic bracelets, make sure the watch's crown is properly screwed down or pushed in. Clean the strap with soapy water then rinse thoroughly. Dry with a soft cloth.

  • Servicing

    Watches are one of those rare objects that operate continuously. To preserve its reliability and extend its lifespan, your watch should be regularly serviced by our certified workshops equipped with all the necessary tools and parts. Only CHANEL watchmakers are officially qualified to repair and maintain your watch.
