Abstract
An alarm setting mechanism for an analog timepiece of the type having a minute hand, an hour hand and an alarm device responsive to switch actuations. A minute setting ring and a coaxial hour setting ring are both rotatably mounted in the timepiece and include a minute alarm marker and an hour alarm marker. Both rings have crown gears coupled to a drive pinion arranged to rotate the two rings at a ratio of 12:1 to set the hour and minute markers. This is preferably accomplished using a spur tooth gear on the minute setting ring and a Geneva drive for the hour ring. A first switch is actuated in response to passage of the hour hand contacting the hour marker and a second switch is actuated in response to passage at the minute hand in close proximity to the minute marker. The alarm setting mechanism has a separate crown which is detented in three positions. The crown enables the alarm setting means to function either as a time of day alarm setting using the hour and minute markers with the conventional timepiece dial indicia, or allows the minute hand to function as a count down timer.
