Abstract
An improved setting mechanism for an electronic watch having a case and circuitry for performing timepiece functions. The setting mechanism includes a setting stem mounted in an opening through the case of the watch. The setting stem is mounted to permit axial and rotational movement of the stem in relation to the case. The setting mechanism also includes a device for generating a first electrical signal which includes incremental electrical pulses in response to a continuous clockwise rotation of the setting stem. The setting mechanism further includes a device for generating a second electrical signal which includes incremental electrical pulses in response to a continuous counterclockwise rotation of the setting stem. The first and the second electrical signals provide inputs to predetermined setting functions for the electronic watch and permit an incremental update of values during the setting functions at a rate directly related to the rate of rotation of the setting stem.
