Wearing your watch is enough to make it work. Thus, each of your movements ensures the automatic winding of the spring and 8 hours on your wrist allows an autonomy of about one day. In case of reduced physical activity or when the watch is not worn much, the movements can be insufficient for an efficient winding. In this case, it is sometimes necessary to wind your watch manually. And if your watch stops for no obvious reason, we recommend that you wind it manually and adjust the various functions. Finally, if in doubt, we are at your disposal to advise you.

If your automatic watch has a date, do not change it when the hour hand is between 9:00 pm and 3:00 am as this means that the date change system is initiated. If you need to set the time during this period, we recommend changing the time by moving the time forward so as not to damage your mechanism.

Approximately every 5 years, you can have your watch serviced when you notice a change in its behavior (power reserve decreasing, decrease in precision, etc.). These adjustments can be made directly with our after-sales service, or with a local watchmaker. For a Quartz watch, the maintenance of your watch includes changing the battery: as soon as the battery is empty, it must be changed, otherwise the mechanism may be damaged.

Watches are precious and sensitive to shocks, so care should be taken. We recommend removing your automatic watch for sports, especially when playing violent sports or for sports in which the watch is subjected to strong shocks as well as centrifugal forces such as tennis or golf.  Even though the sapphire crystal of your watch is designed to prevent irreversible damage to your dial, it is best to avoid any form of shock that could harm the mechanism of your watch.

Do not wear your automatic watch in the shower, even if it is a waterproof watch. Heat can expand the seals. If you use your watch for swimming or diving (10ATM or more), we recommend that you have the water resistance checked every 2 years. If you own the Concordia, your watch is perfectly waterproof. Please make sure to screw in the crown before each swim, otherwise the mechanism may be damaged. After a swim in sea water, rinse your watch with fresh water.

Finally, avoid prolonged or too close exposure with a magnetic wave source (electronic objects, induction plates, medical devices, etc.). This could magnetize the movement, causing your watch to behave erratically. These waves will not damage your timepiece but rather degrade its operation and accuracy. If your watch is magnetized, the most frequent sign is a sudden and important advance. It is necessary in this case to entrust the watch to us or to go to a watchmaker, to demagnetize the watch.

Choose the right strap: there are leather, steel and nylon strapsthat are more or less suitable for the different activities you may perform. Leather straps are the most delicate, sensitive to water and heat. For summer or sports practice, we advise you to opt for a nylon strap, or a steel strap if you do not want to damage it.The maintenance of your nylon or steel watch strap will be easier, simply clean it with fresh water and soap before drying the whole with a dry cloth.
