The biggest problem with this is that when changing the weight you link have to be hyper-precise, Hines said. "If you're off by even a fraction of a millimeter, it's going to impact the rate drastically because now you've got a heavier weight on one side. With the new Spirate System, my speculation is that the balance will be preset by the factory and then you'll use the hairspring regulating system link for link adjustments."
