Prachtig!
36.000 bph toch? Doet ie er dan geen 10 per seconde? .
Quartz?
Voila.
Het 9F uurwerk in de Grand Seiko heeft een twin-pulse motorā¦en de secondewijzer doet 2 stappen per seconde.
In a normal quartz movement, the second hand moves in a single step from one second to the next. In the 9F quartz movement, the second hand instead makes two consecutive steps per second, triggered by two successive pulse signals. Increasing the number of pulse signals augments the output torque from the rotor, enabling the use of heavier hour, minute, and second hands. This two-step process is undetectable by the naked eye and appears as a single step no different from standard quartz timepieces.
