Automatic Watch - Automatic Quartz or Kinetic Movement

Automatic Quartz or Kinetic Movement

More recently, electronic automatic quartz watches powered by arm movement have been developed. A weighted rotor turns a tiny electrical generator, charging an accumulator, such as a rechargeable battery or capacitor, which powers the quartz movement. This automatic quartz arrangement provides the accuracy of a quartz movement without the need to replace the battery or capacitor until it reaches the end of its life, which may be decades. This innovation was introduced by Seiko.

Famous quotes containing the words automatic, kinetic and/or movement:

    Predictions of the future are never anything but projections of present automatic processes and procedures, that is, of occurrences that are likely to come to pass if men do not act and if nothing unexpected happens; every action, for better or worse, and every accident necessarily destroys the whole pattern in whose frame the prediction moves and where it finds its evidence.
    Hannah Arendt (1906–1975)

    The poem has a social effect of some kind whether or not the poet wills it to have. It has kinetic force, it sets in motion ... [ellipsis in source] elements in the reader that would otherwise be stagnant.
    Denise Levertov (b. 1923)

    An actor rides in a bus or railroad train; he sees a movement and applies it to a new role. A woman in agony of spirit might turn her head just so; a man in deep humiliation probably would wring his hands in such a way. From straws like these, drawn from completely different sources, the fabric of a character may be built. The whole garment in which the actor hides himself is made of small externals of observation fitted to his conception of a role.
    Eleanor Robson Belmont (1878–1979)
