Calendar timepiece

A calendar timepiece comprising:

• a main plate having a groove portion;
• a date indicator driving wheel mounted on the main plate to undergo rotation;
• a date feed finger connected to the date indicator driving wheel for rotation therewith;
• a date indicator having a tooth portion for meshing engagement with the date feed finger for undergoing rotation relative to the main plate to indicate date information during rotation of the date feed finger, the date feed finger engaging the groove portion of the main plate during rotation thereof in order to secure meshing engagement between the date feed finger and the tooth portion of the date indicator in a thickness direction of the main plate;
• a day feed finger connected to the date indicator driving wheel for rotation therewith;
• and
• a day indicator connected to the day feed finger for rotation therewith to indicate a day of the week.

A calendar analog electronic timepiece comprising:

• a main plate having a guide portion;
• a date indicator driving wheel mounted on the main plate to undergo rotation;
• a date feed finger connected to the date indicator driving wheel for rotation therewith to engage the guide portion of the main plate so that the date feed finger is displaced in a generally thickness direction of the main plate;
• a date indicator having a tooth portion for meshing engagement with the date feed finger when the date feed finger engages the guide portion of the main plate and is displaced in the thickness direction of the main plate so that the date indicator undergoes rotation relative to the main plate to indicate date information during rotation of the date feed finger;
• a quartz oscillator for producing an oscillating output for use as a time base of the calendar analog electronic timepiece, the quartz oscillator having a portion disposed in overlapping relation with the date indicator;
• and a step motor having a rotor, a stator spaced from the rotor, and a coil block for magnetizing the stator to rotate the rotor, the coil block having a portion disposed in overlapping relation with the date indicator.

A calendar timepiece comprising:

• a main plate;
• a date indicator driving wheel mounted on the main plate to undergo rotation;
• a date feed finger connected to the date indicator driving wheel for rotation therewith;
• a date indicator having a tooth portion for meshing engagement with the date feed finger so that the date indicator undergoes rotation relative to the main plate to indicate date information during rotation of the date feed finger;
• and
• displacing means for displacing the date feed finger to a preselected position in a thickness direction of the main plate to secure meshing engagement between the date feed finger and the tooth portion of the date indicator.
