the above statement is wrong and I wish to correct it, the movement Z-601 was entered in the 1965 Neuchatel Observatory trials, adjusted by Rene Gygax and achieved a Premier Grading with a N-Score of 5.58 and ranked 109 and was also entered in the following years trials of 1966, adjusted by Rene Gygax and achieved an N-Score of 4.39 and ranked 97.
