  • Day and time chronometer movement
    Patent number: 8526272
    Abstract: A day clock has day, hour, and minute hands revolving continuously around a common center. It has a time adjustment knob and a day adjustment knob. When the day adjustment knob is pulled out, a set of gears are disengaged, allowing the day hand to be adjusted with that knob without affecting the other hands. Then, when the set of gears are reengaged, the time adjustment knob can be utilized to set the time of day. In order to set the day and time accurately, the user may first set the time to midnight with the time adjustment knob, pull out the day adjustment knob, set the day to a clock face line between days with that knob, push that knob back in, and then set the time to the correct time with the time adjustment knob.
