How Does a Grand Seiko Spring Drive ACTUALLY Work?

So what actually is Spring Drive? Some Grand Seiko watches feature Spring Drive, which allows a perfectly smooth seconds hand. In simple terms, Spring Drive combines a traditional watch movement and an electrical regulator, leading to superior accuracy.

You didn't actually say what Spring Drive is, or even show it. As an example; you say it's got an electronic regulator - so does it have a battery???

[mikes.]

Spring Drive is the most elegant, sophisticated, and precise movement.

[TheGrenadier]

Mechanical in everything except in how it controls the speed of the glide wheel, which is the equivalent to a escapement lever. Heavily misunderstood, and personally i think this is the ultimate blend of both worlds.

So is there a battery? Solar? Where does it get the power?

Their clasp still suck. They don’t listen to their customers

[mikegreene]

Fifteen seconds a month is not very accurate.
