Abstract:
A setting mechanism for an electronic timepiece having a case and circuitry for performing timepiece functions disposed within a cavity of said case, said setting mechanism comprising:a setting stem mounted in an opening through said case and operative for axial and rotational movement in relation to said case;means for retaining said setting stem in said cavity and releasably securing said setting stem in a plurality of axial setting positions in response to said axial movement of said setting stem;a click-wheel assembly frictionally mounted on said setting stem for selective coaxial rotation therewith, said click-wheel assembly having a first click-wheel and a second click-wheel, each of said click-wheels having a predetermined number of teeth disposed about a respective outer diameter thereof;a first elongated arm which cooperates with said teeth of said first click-wheel and a first signaling arm for causing incremental electrical pulses when said first elongated arm engages said teeth of said first click-wheel during rotation in a first direction; anda second elongated arm which cooperates with said teeth of said second click-wheel and a second signaling arm for causing incremental electrical pulses when said second elongated arm engages said teeth of said second click-wheel during rotation in a second direction;wherein said first click-wheel is prevented from rotating relative to said first elongated arm when said setting stem is rotated in said second direction and said second click-wheel is prevented from rotating relative to said second elongated arm when said setting stem is rotated in said first direction;whereby said first signaling arm only causes incremental electrical pulses when said setting stem is rotated in said first direction and said second signaling arm only causes incremental electrical pulses when said setting stem is rotated in said second direction.
