Check water resistance every 2 years (every year if in frequent contact with water)

Servicing every 4 to 5 years

Your watches water resistance features are engraved on the case back next to the fish marking. However, we do not recommend completely submerging your watch in water to avoid damaging the strap. 

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 in water. 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 check the water resistance of your watch case 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.

For maximum accuracy and reliability, we recommend not wearing your watch when playing a potentially high-impact sport like tennis, golf, and horseback riding. Also, stay at least 10 cm away from highly magnetised objects like smartphones, tablet computers, induction hobs, speakers, TV screens, and airport security detectors. For more information about magnetisation, please read the Watchmaker's Advice section.

BOY·FRIEND watches equipped with a mechanical movement need to be manually wound to tighten up the mainspring that operates the movement. This is done by turning the crown clockwise until it stops turning, which means the movement is fully wound (approximately 25 full winds of the crown).

The watch has a power reserve of 55 hours. It must be manually wound when the power reserve runs out. To maintain the accuracy of your watch, we recommend winding the movement every day (approximately 12 full winds of the crown).

Our leathers are very carefully selected and undergo numerous tests to ensure they are of the highest quality. Nevertheless, leather is an organic material that acquires a natural patina over time. Do not get your leather strap wet to avoid damaging it.

Use only a clean and dry soft cloth to clean your strap. Do not use chemicals like soap, alcohol or solvents.

Go back to THE STRAP

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.
