摘要:
The invention concerns a running equation of time mechanism including a hand arrangement whose purpose is to indicate civil time by means of an hour hand and a minute hand, and a true minute hand concentric with the civil minute hand, and which indicates the true solar minute, wherein the running equation of time mechanism also includes an equation of time cam having a profile which is determined by the difference, on each day of the year, between civil time, and true time, wherein this equation of time cam is driven in rotation by a calendar mechanism, wherein the position of the true minute hand is determined by the position of the equation of time cam, wherein the running equation of time mechanism also includes a differential gear device, a first input of which is formed by a civil minute pipe on which a civil minute hand is pressed, and a second input of which is formed by the equation of time cam, wherein the differential gear device includes a planetary reducer wheel set via which the civil minute pipe drives a civil hour pipe on which is pressed the civil hour hand, and a planetary multiplier wheel set via which the civil hour pipe drives a true minute pipe on which is pressed the true minute hand.

The timepiece movement (1) includes a karussel (4) whose platform carries an escape wheel that cooperates with a balance (7). The platform is driven from the time display mechanism associated with a time-setting mechanism (32). The escape wheel is driven directly from the gear train. In addition to compensating for differences in rate due to gravity, the karussel of the invention proposes a new, complementary role: that of time indicator.

The invention relates to a watch provided with time indicators with three dimensions placed at the periphery of the movement of the watch, in the space delimited by the middle, the glass, the base and the movement. The movement of these indicators is provided by various clockwork mechanisms that are either independent or connected to the principle movement.

A calendar indicating device can include easy placement through a north-south block (1) to orient an equinox line (3) to provide sunrise shadow indications of one or more solstice events such as the summer solstice or the winter solstice at the moment of sunrise. Designs can be based on remnants of artifacts that included some of the possible components, even for prehistoric man, in one integral stone device built from a stone base (2). Embodiments may include sunset indicator(s), solar altitude indicator(s), indicators for the maximum solar altitudes on the summer and/or winter solstice dates, and alignment aid(s).

摘要:
The present invention concerns an electronic astronomical watch, in particular of the wristwatch type, said watch (1) being capable of indicating the position of celestial bodies in the heavens, said watch (1) including: a time base (48) for producing a standard frequency signal; means (50) for determining the current time and date from the standard signal means (28, 30) for selecting a celestial body; analogue time display means using two hands (10, 12); means (32) for determining the position of the selected celestial body in the heavens and indicating this position via the display means (10, 12), the watch (1) being wherein it includes a rotating dial (14) on which there is shown the map (16) of the heavens and in that the shape of the hands (10, 12) is such that their intersection or point of conjunction enables any point of the map of the heavens (16) to be designated on the dial (14).
摘要:
The clock shows time as a function of the earth's rotation in a way that distinguishes universal time from local solar time, according to where the user resides within his or her time zone. Time is indicated by movement a marker at the user's location on a rotating polar projection map of the earth.
摘要:
A clock for automatically indicating the time of day, the data of the year, the approximate time of sunrise and sunset, the approximate hours of darkness and daylight, the positions of the sun, Mercury, Venus, the earth's moon and phases of the moon, the sign of the Zodiac and degrees of arc of the sign of the Zodiac which the earth is in, all relative to the earth in a geocentric model. The clock includes a center hub representative of the earth, about which an hour disk rotates one revolution clockwise per day, a superposed data disk, an hour pointer and data pointer for indicating the hour and calendar data. The clock further includes a cam lever that oscillates about a pivot point in response to movement about a stationary cam at one end for automatically rotating Venus and Mercury indicators about a sun indicator, and automatically rotating a moon indicator about the center hub. Sun, Mercury, Venus indicators also rotate about the center hub. The clock further includes outer planet indicators which are manually movable.
