If you own a Self Winding Automatic Watch Read This.
We hope you find the following information about your timepiece informative and that it will better assist you in the proper functioning of your watch.
You may experience that your self-winding watch occasionally stops overnight or appears to be running slowly. This does not necessarily indicate a malfunction or defect in the watch. In most cases, the problem is related to the power reserve that has not been properly initiated or, may be the result of too insufficient wrist action while wearing the watch.
For a self-winding watch to function properly, the mainspring must build up a sufficient power reserve. Many people are unaware that a self-winding watch needs to be wound first manually before it will run automatically. This is called the initiation process. Without the initiation process, the watch will never operate properly or consistently.
To initiate the power reserve, the watch must be wound manually. Turn the winding crown at the 3 o’clock position, in a clockwise direction for about 40 revolutions. This start up wind is usually sufficient for most automatic watches.
After completion of the initiation process, the watch will wind itself automatically (rebuilding the power reserve) by means of an oscillation weight that shifts every time the watch’s position is changed by the action of the arm and wrist.
A self-winding watch should be worn at least eight hours a day to maximize the power reserve. If this is not possible, or if the watch has been off the wrist for more than 15-20 hours, the initiation process must be repeated.
