Abstract:
A calendar timepiece has a main plate having a guide portion and a date indicator driving wheel mounted on the main plate to undergo rotation. A date feed finger is 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 has 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 day feed finger is connected to the date indicator driving wheel for rotation therewith. A day indicator is connected to the day feed finger for rotation therewith to indicate a day of the week.
