Important Information: For automatic watches, you must fully wind it the first time you use it. To fully wind your watch, turn the crown clockwise approximately 30-40 times or wear it on your wrist for at least 8 hours. If your watch is not fully wound, it will lose time. Please follow the steps above to check timing accuracy. Do not adjust the day/date if your automatic mechanical watch displays the time between 9 PM and 4 AM. This will cause it to be incorrect due to changes in the mechanism. Calendar readjustment will be required.
