In order for automatic self-winding timepieces to operate properly, there must be enough power reserve built in the mainspring. Many people and owners of these automatic mechanical timepieces are unaware that self-winding watches need to be wound first manually, before it will run automatically. This is known as the initiation process.
To initiate the power reserve of your watch, turn the crown located beside the 3 o'clock position, in a clockwise motion for about 20-30 rotations.This initiation process is usually sufficient for most automatic watches. You can also watch the video below for visual instructions.
After this process has been completed, the watch will begin to automatically self-wind rebuilding the watches power reserve by means of natural movements whilst on your wrist.
An automatic watch should be worn for at least eight hours a day to maximise the power reserve. If this is not possible, or if the watch has not been worn for more than 18 hours, the initiation process must be repeated.
