Id like some advice on regulating this watch. Its a Jules Jurgensen Movement and what Im not understanding is adjusting the regulation. In the photo you can see the part that you rotate, effectively making the hairspring longer or shorter. There is a notch in that piece diectly opposite the arm that retains the end of the spring. Is that notch supposed to line up with the plus and minus scale? If so its way off. The watch does run fairly slow. But, when I move it towards plus so that the notch is in range with the scale, the balance wheel stops. Also, there is another arm that kind of guides the spring and when I move the main lever, it moves along with it. Is this right? So that the position of the 2 arms is always the same? Thanks in advance for any advice.
