The Automatic watch winds itself when it is worn by a person with only the motion of the arm. This motion is created by a mechanical process that involves the movement of the wrist and the body that makes the rotor (a metal weight attached to winding mechanism) rotate back and forth in a circular motion at the slightest action of the wrist. The rotor’s movement winds the mainspring, a flat coiled spring that powers mechanical watches. That is why this watch is also called self-winding watch.

If you wear your Automatic Watch daily, it is good to wind it once every two weeks with the crown to keep the wheels in motion and oil fluid. Only wind the crown until you meet a slight resistance.

If you do not wear your Automatic watch everyday, you should wind it at least twice a week to ensure continuous operation and to keep the inside mechanism in complete running order as well.

If you haven’t worn an automatic watch in a while, it is best to wind the stopped watch before putting it on. Ten to fifteen turns of the crown until you feel a slightly resistance is usually enough to give full power to the mainspring. Some companies recommend more: Breitling, for example, suggest turning the crown on its automatics 30 to 40 times. But be aware that the barrel in an automatic movement doesn’t have a hook so that you won’t feel any resistance when the mainspring is fully wound. Don’t worry; you will never overwind the watch.

Avoid setting the day and/or date at near midnight. This mechanism is activated during midnight and could be disrupted if set at this time.

If you are playing a sport requiring continuous arm motion, please try to avoid wearing your watch, since this kind of continuous motion could damage the movement.

Take your watch in every year or two to a competent watch repair shop for a maintenance (lube job). Most watches will function just fine with a lube and tune once every two years, although with today’s modern synthetic lubricants, most will run just fine for almost 4 or 5 years.
