I've a pair of Spring Drive GSs, but not automatics. The level of dial finishing is beyond any other make I've owned or seen in the flesh, but they are let down by the bracelets which typically don't have micro adjustments (unfortunately the exceptions to this are few and far between).
Their automatics accuracy isn't quite up there with e.g. Rolex as far as I'm aware? Then again what they claim for accuracy is typically conservative, with owners reporting better accuracy than advertised (certainly been my experience).
