Electronic device with calendar function

An electronic device comprising a display assembly comprising a dial having a viewing window, the electronic device comprising:

• a first rotateable ring having a plurality of dates thereon;
• a second rotateable ring, overlying the first rotateable ring, having a plurality of dates thereon;
• means for:
• rotating the first rotateable ring so as to cause a selected subset of the plurality of dates to be positioned within the viewing window;
• and
• rotating the second rotateable ring so as to cause a selected subset of the plurality of dates to be visible in the viewing window;
• wherein:
• the overlying of the second rotateable ring over the first rotateable ring causes dates of the first rotateable ring positioned in the viewing window to be non-viewable in the viewing window;
• and
• selected rotation of the first and second rotateable rings causes different subsets of the respective plurality of dates on the respective rotateable rings to be positioned within the viewing window;
• whereby the position of the second rotateable ring over the first rotateable ring in the viewing window causes the viewability of differing sequences of dates in the viewing window.

An electronic device comprising a display assembly comprising a dial having a viewing window, the electronic device comprising:

• a first rotateable ring having a plurality of dates thereon;
• a rotateable member that overlies the first ring, wherein the rotateable member has a plurality of dates thereon;
• one or more stepping motors and gearing assemblies for:
• rotating the first rotateable ring so as to cause a selected subset of the plurality of dates to be positioned within in the viewing window;
• and
• rotating the rotateable member so as to cause a selected subset of the plurality of dates to be visible in the viewing window;
• wherein:
• the overlying of the rotateable member over the first rotateable ring causes dates of the first rotateable ring positioned in the viewing window to be non-viewable in the viewing window;
• and
• selected rotation of the first rotateable ring and the rotateable member causes different subsets of the respective plurality of dates on the respective first rotateable ring and the rotateable member to be positionable in the viewing window;
• whereby the position of the rotateable member over the first rotateable ring in the viewing window causes the viewability of differing sequences of dates in the viewing window.
