The only opinion is yours when you continually and incessantly bash this movement without first hand experience. You are basing your "opinion" on an assumption that a movement is inferior which I am sure it is as compared to many others (IWC or otherwise). The fact remains that a bunch of us owners find it to be accurate and reliable for as long as we've owned it. Maybe in a few years when some of us discover that the movement was not so reliable after all, you can come back and tell us "I told you so."
