Access to a programming mode of a perpetual calendar feature built into the watch is controlled by requiring at least one manipulation of a time-setting rod in view of its attribution to at least one function other than the functions of correction of the date and day, and to control the watch in the manner of an ordinary watch in the second case and to attribute, in this case to at least one manipulation of the rod, the functions of correction of date and day.

Abstract: A first mechanism (2, 5, 8, 18, 20) of the calendar drives a date indicator, bearing numbers 1 to 30, by one one-day step at the end of each day, off a rotary part (1) of an analog timepiece movement. A second mechanism (60, 62) causes the date indicator, in cooperation with the first mechanism, to move forward from the 29th to the 1st of the following month at the end of the even months. A third mechanism (75, 79, 95, 97) inhibits the action of the second mechanism at the end of the embolismic (or abundant) years whereby at the twelfth and final month of these years the date indicator displays 30 before proceeding to the 1st. The calendar is perpetual, and a date-corrector (11) and a month-corrector (54) enable the calendar to be updated.

Abstract: The clock movement comprises a perpetual calendar mechanism (1-15), an equation-of-time mechanism (16-19) and a third mechanism (20-23) which is actuated by the first so as to modify the angular position of an equation-of-time cam (16) of the second mechanism, as a function of the number of days in the months. Thus this cam (16) always performs exactly one complete revolution in one year, irrespective of the number of days in the year. The movement is therefore a perpetual calendar movement and a perpetual equation-of-time movement. It also has the advantage that, after it has been stopped for an indeterminate time, the exact angular position of the equation-of-time cam (16) is automatically restored, with no possibility of error, simply by bringing the date, year, month and time back into phase.

Abstract: A method of simultaneously displaying day calendar information in first and second view ports, each of which displays it's calendar data in a different format. The information in the two simultaneously displayed view ports is functionally interrelated to provide an improved interactive user interface.The first viewport has a time structured format which displays a sequence of predesignated time slots, each of which represents a fixed period of time, such as 30 minutes. Each time slot is allocated to one display line in the viewport. If the number of time slots allocated between the beginning and end of a calendar day is greater than the number of display lines in the viewport, then the information is scrollable so that the entire day may be viewed by the operator. The first viewport also includes at least one column that is used to display a vertical busy bar adjacent to a time slot which indicates that the slot is already scheduled.
