Точность
Results of rate test:
(When fully wound / after 24 hours / after 39 hours)
(Deviations in seconds per 24 hours)
Dial up: +1 +2 +2
Dial down: +3 +5 +4
Crown down: 0 +1 +2
Crown left: +3 +5 +2
Crown up: +1 +3 +3
Crown right: 0 +1 +2
Greatest deviation of rate:
3 4 2
Mean deviation:
+1.3 +2.8 +2.5
Mean amplitude
flat positions: 292° 259° 245°
hanging positions: 276° 244° 223°
Maximum difference
between the vertical
positions: 4° 3° 5°
Выводы:
The superlative quality of all components
in the movement is borne out by the excellent
rate results. We discovered “plus” values
(gain) in all six tested positions, and only minimal
differences in amplitude, not only when
fully wound, but also after 24 and 39 hours.
Я думаю с надёжностью в порядке, калибру 3+ года - о проблемах информации не встречал.
