    Seiko-5 How the hell does it stay wound

    I own a Seiko5 military in the canvas strap and am amazed by this movement.How does it manage to stay wound with out winding by the crown.It must have a very efficient main spring and rotor and such in order to do this.Can someone please enlighten me on this particular movement?

    Well, that's what auto movements do; wind as you move them around. Those little Seikos do spin up quickly though..

    An automatic movement has a rotor inside which spins when the watch is in motion. As you wear the watch through normal activities the rotor spins and winds the movement. After a full day if wear it should continue to run at least 36 hours or more while motionless before it runs out of power.

    As others have stated above .......It was a great piece of reverse engineering that came from the Roswell UFO crash....

    Is this question for real????

    If it is, well, Seiko's magic lever also helps to keep it going efficiently.

    Teeny, tiny nuclear reactor. You'll need to take it in for service in about 2085 to have the fuel rod replaced.👿

    The movement from your arm and wrist are captured as energy within the watch to wind the spring that powers it.

    Very funny you wisenheimers I know dam well how an automatic watch works.Just curious how the Seiko 5 does it so well just by movement of the wrist alone.Some watches require a pre windup charge of any where from 20 to 40 winds of the crown to get them going then the rotor can do the rest.The Seiko 5 doesnt require this and I was amazed how Seiko pulls this off
