There is a lot of confusion about the Seiko Spring Drive...It is NOT a quartz movement.  It is a completely mechanical movement that has a micro-chip in it to regulate (on a "real time" basis) the release of the mainspring to produce "quartz-like" accuracy.  It is much like the engine of a car that uses micro-chips/computers to regulate functions of the engine like timing, fuel consumption, cylinder usage, etc.  The car is still powered by an engine and not by the computer.
