… every of these women adds another or several components. Then the movement then continues in its designated flow and is handled over to the next colleague …

… my photograph shows in the middle the chronograph movement in which another component will be added …

… by standardising the work flow the quality and speed is increased. Of course the ladies rotate during the week and they do not always do the same operations …

… one movement after the other shows up …

… start, stop, reset …

… and again start, stop, reset …

… the assembly chain of the chronograph movement …

… regulating the assembled chronographs …

… step by step the chronometry is improved …

… Measurement of the rate accuracy, the amplitude and the beat error of mechanical watches is done with Swiss Witschi Electronic equipement…

… the Witschi measures the movement in six positions …

… experts know what to do if a movement does not regulate as it should …

… in the end the only thing that counts is accuracy …

… accuracy for a long period of time …
