Definitions

  • the present invention relates to a timepiece comprising a time equation mechanism with display. More particularly, the invention is directed to a walking time equation mechanism operating a true time minute hand that indicates the gap between true solar time and civil time.
  • certain timepieces include a mechanism said to equation of walking time, that is to say whose switch has two minute hands, one indicating the civil time and the other the true time, the minute hand of the true time being actuated by a weather equation cam whose profile is determined by the difference between the mean solar time and the true time at a given instant .
  • the cam is rotated at the rate of one revolution per year by a simple or perpetual calendar mechanism.
  • the simple date is a mechanism that can indicate the day of the week, the day of the month, the month of the year or the phases of the moon, but which does not take into account the variation of the number of days in the months (months of 28, 29 or 30 days).
  • the user of a watch comprising a simple date mechanism will have to make a manual correction every month ends that are less than 31 days. For example, February 28 or April 30 will require manual correction.
  • the perpetual calendar it allows, as a simple date mechanism, to indicate the day, the date, the month and the moon phases. But, unlike the simple calendar mechanism, the perpetual calendar mechanism automatically takes into account the length of the months (28, 29 or 30 days), and this without manual intervention. A perpetual calendar mechanism therefore automatically takes into account leap years.
  • the Swiss calendar time is incremented by one additional hour, so that it is two hours ahead of the Greenwich civil time.
  • the sun is 6.57 min behind the civil time.
  • the Greenwich civil time is 12h 07min.
  • the watch will indicate 1 hour more, that is 13h 07min.
  • the sun is 5.06 min behind schedule.
  • the civil time of Greenwich is 12h 05min. In Switzerland, however, the watch will show two hours more, 14:05 min.
  • the object of the present invention is to overcome the aforementioned drawbacks as well as others by providing a date timepiece comprising a walking time equation device which makes it possible to indicate the exact civil time of the timepiece. where you are when the sun goes to its zenith.
  • the present invention relates to a timepiece comprising a watch movement and a date mechanism, this timepiece having a pair of hour and minute hands which indicate the calendar time, and an extra minute hand which indicates the minute of the true time and which is driven by a true time display gear, the daily position of the minute hand of the true time being determined by the position of an equation cam rotated time at a rate of one revolution per year from the date mechanism, characterized in that the display gear of the true time causes a mobile carrying an extra hour hand which indicates the true time and in that that a pavement of equation mounted free on a gun of the minutes of the true time at the end of which is fixed the minute hand of the true time drives in rotation by means of a coupling
  • an additional pavement is fixed on the barrel of the minutes of the true time
  • the clockwork of the real time comprising a differential mechanism which has for input the time equation cam and for output the equation pavement.
  • the present invention provides a timepiece whose walking time equation mechanism provides a complete indication (hour and minute) on the true solar time. So when the solar time coincides with civil time (this occurs four times a year), the true time switch provides the same indication as the civil time switch at the center of a time zone such as the Greenwich meridian. On the other hand, when the solar time is in ahead or behind the civil time, the true time hour hand provides the same indication as the civil time hour hand, while the true time minute hand is delayed or shows an advance of a few minutes on the minute hand of the civil time. This is true, however, only in the center of the time zone on which the equation of walking time is based.
  • the timepiece comprises a correction device that shifts the calendar time indicated by said timepiece according to the calendar time of a time zone reference without changing the indication of true time.
  • the watch according to the invention which has been previously set by its user to provide an indication of the civil time in Switzerland will display 13h 07min when the sun will be at its zenith.
  • the watch will show 14:05 min, while the true time switch will show 12:00. Therefore, whatever the the time zone in which the wearer of the watch is located, he will know at all times the exact difference between the civil time and the solar time.
  • the present invention proceeds from the general inventive idea of providing a timepiece which provides, in addition to an indication of the minute of true time, an indication of the time of the true time.
  • a timepiece which provides, in addition to an indication of the minute of true time, an indication of the time of the true time.
  • the civil time of the place where one is differs from the reference time of said time zone, this difference being able to be induced by the passage of the winter time to summer time and vice versa.
  • it is proposed to increment or decrement the indication of the civil time in steps of one hour without changing the display of the true time. This gives an indication of the passage of the sun to its zenith corresponding to the civil time of the place where one is.
  • the present invention will be described in connection with a timepiece of the wristwatch type comprising a walking time equation mechanism actuated by an equation cam, itself driven in rotation at the rate of one revolution per year to from a date mechanism that can be indifferently simple or perpetual.

  • the hour and minute hands of the real time can be reset by the user himself at the end of the months of the year with less than 31 days since the determination of the difference between the two hands of the minutes of the civil time and the true time is defined by the equation cam of the time driven by the date mechanism.

We see on the figure 2 that the indication of the month of the year is done by a needle 4. Of course, the needle 4 could be replaced by a disc which would bear the inscription of the months of the year and which would turn under the dial 1 leaving appear the name of the month by an opening in said dial 1 and called wicket.

  • This time scale 22 is graduated hourly and extends between -4 and +4 hours, which corresponds to the maximum time difference that can be note between the civil time of a given place on the earth and the civil time in the center of the reference time zone to which this place belongs. The user thus instantly knows the value of the offset applied to the calendar time displayed by the watch relative to the civil time in the center of the spindle.
