What is an Automatic?
An automatic is a mechanical watch whose mainspring is wound as a result of the wearer's arm motion.
1. To start unscrew crown anti-clockwise until you feel it has unscrewed. Then wind clockwise. You will feel the crown turning freely. Wind 15 turns clockwise.
2. To set time pull crown out gently until it is fully out, then turn crown to set correct time
3. To return push crown in. Then turn 1/4 of a turn anti-clockwise keeping gentle downward pressure on crown and then reverse the turn clockwise while maintaining downward pressure on the crown. Continue until crown is finger tight.
How does an automatic watch work?
The movement of the wrist and body causes the rotor, a metal weight attached to a winding mechanism, to pivot freely on its staff in the center of the movement. The rotor rotates 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.
How much motion does an automatic need to work properly?
A person's normal arm and wrist motion will keep an automatic watch properly wound. People who are inactive--the elderly or patients confined to beds may need to wind their watch to keep it powered.
Is it safe to wind an automatic watch?
Sure. Winding the watch won't hurt it at all. If you haven't worn an automatic in a while, it is best to wind the stopped watch before putting it on. Ten to 15 turns of the crown is usually enough to give full power to the mainspring.
