MANUAL WINDING MECHANICAL MOVEMENT

J12 DIAMOND TOURBILLON CALIBER 5

The water resistance for sapphire watches is 30 meters, and for ceramic watches, it is 50 meters. However, to avoid damaging the strap, you should not immerse your watch entirely under water.

Water resistance means that the movement is protected from dust, moisture and any deterioration should it be submerged in water up to those depths. Watches are water-resistant thanks to their seals. To ensure continuous water resistance, it is recommended to replace the seals every two years from the date of first use. It is also advised to test your watch’s water resistance every year if the watch has been exposed to sea or pool water for long periods of time. Never adjust the crown while it is submerged in water because the water 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 damage the water-resistant seals.

Condensation under the crystal indicates that water has gotten 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, or horseback riding. Also, stay at least 10 cm away from highly magnetized objects like smartphones, tablet computers, induction hobs, speakers, TV screens, and airport security detectors. For more information about magnetization, please read the Watchmaker's Advice section.

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 42 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).
