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 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.
Your watch is equipped with a self-winding mechanical movement that winds itself with the movement of the wrist, which causes the oscillating weight to turn on its axis. The power reserve can be affected if the strap is not adjusted correctly, so it is important that your watch is properly fitted. When the watch is not being worn, it has a power reserve of 38 to 70 hours (depending on the model). It must be manually wound when the power reserve runs out. If the watch remains idle, we recommend winding it manually every two or three weeks (20-25 winds of the crown) so the movement's lubricating oils stay intact.
Important: It is best not to adjust the date between 10:00 PM and 1:00 AM.
