Definitions

  • the invention relates to a timepiece with two hands with analog display. More specifically, the invention relates to a timepiece having only two needles, which can display functions different from those to which they are initially intended or to display information in a different way compared to the way , of which they are initially displayed.
  • the battery voltage decreases thus causing the disruption of the operation of the timepiece and when the end of battery life is reached, the timepiece stops working.
  • to announce the end of life of the battery can be provided with the timepiece of a light element, which has a predetermined operating voltage, and the light element produces intermittent light signals.
  • the light element is normally kept in an inactive state, but it can produce intermittent light signals when the battery voltage drops below a predetermined value.
  • the power consumed is important so that it is necessary to use a battery having a larger capacity.
  • the power consumption increases when the end of life of the battery approaches, which accelerates the depletion of the battery.
  • a timepiece especially a two-needle timepiece
  • Another problem encountered with a timepiece, especially a two-needle timepiece is that it is not possible to easily manipulate the needles, or to change the way of their normal operation.
  • a two-hour timepiece has an hour hand to indicate hours, and a minute hand to indicate minutes.
  • the object of the present invention is therefore to overcome the problems identified above related to electronic timepieces with analog display.
  • the present invention therefore proposes a two-pointer electronic timepiece with an analogue display, as explained in more detail below.
  • the subject of the invention is, according to a first aspect, a two-hand electronic timepiece with an analogue display according to independent claim 1.
  • a timepiece having the possibility of displaying several functions with a two-needle movement. Said movement is thin with a reduced movement price.
  • the movement is composed of few mechanical components compared to a three-needle movement.
  • the proposed timepiece makes it possible to have a display of the second on demand by a simple two-needle movement.
  • the proposed timepiece also displays the end of life of the battery with a two-hand movement.
  • the present invention aims at displaying on demand, in particular, the hour and the minute, the date and the second with only two needles.
  • the watch of the present invention comprises only two needles, in particular a first needle as illustrated is an hour hand, and a second needle as illustrated is a minute hand.
  • the watch 1 which is shown diagrammatically, comprises a power supply 3 constituted by a battery, which supplies an electronic circuit and, through this circuit, a first electric motor 7, which actuates the hour hand 9, and a second electric motor 8, which actuates the minute hand 11.
  • a power supply 3 constituted by a battery, which supplies an electronic circuit and, through this circuit, a first electric motor 7, which actuates the hour hand 9, and a second electric motor 8, which actuates the minute hand 11.
  • Both electric motors can be stepper motors, for example.
  • the dial 13 of the watch is visible behind the needles 9, 11.
  • the electronic circuit mainly comprises a quartz oscillator (not illustrated) associated with a microprocessor 5 of the watchmaker type, which directly controls the motors 7, 8, as well as a circuit 15 for controlling the voltage of the battery.
  • This control circuit 15 essentially comprises a comparator 17, a special circuit 19 arranged for storing for example a reference voltage threshold, or an internal resistance threshold, and two resistors 21 and 23 respectively called resistors of the divider bridge.
  • the special circuit 19 is known in particular by the Swiss patent CH 651 999 .
  • a connection node 25 of the two resistors 21 and 23 is connected to a positive input of the comparator 17.
  • the other terminal of the resistor 23 is connected to the ground T.
  • the other terminal of the resistor 21 is connected to the positive terminal of the pile.
  • the negative input of the comparator 17 is connected to a terminal of the special circuit 19, whose other terminal is connected to the ground T.
  • the output of the comparator 17 is connected to the microprocessor 5.
  • the control circuit 15 is arranged to detect the voltage of the battery or its internal resistance and to compare it with a predetermined threshold value. When the actual value of the voltage or of the internal resistance reaches the respective threshold value, the control circuit 15 transmits appropriate information to the microprocessor 5, which controls the motors 7, 8.
  • a first mode of operation may be considered a normal mode of operation, while a second mode of operation is an alternating mode of operation.
  • the second mode of operation is activated by an event detected by the watch. This event may be for example an action performed by the wearer or user of the watch 1, or an event, which does not require any intervention by the wearer of the watch 1.
  • the watch may return to the first operating mode, after detecting a specific event or after a specified time.
  • the hour hand 9 operates in a jump-defined manner.
  • the hour is jumpingly indicated by the hour hand 9.
  • the hour hand 9 is positioned on the dial 13 at position "1" as shown in FIG. figure 1 then from 2:00 pm to 2:59 pm at position "2", and so on.
  • the hour hand 9 makes a jump every hour, that is to say a jump per hour.
  • the minute hand 11 indicates the minutes of jumping or slippery way.
  • the watch displays the hour and minute.
  • the second mode of operation is not necessarily related to the fact that the stack 3 approaches the end of life threshold.
  • the second mode of operation can be initiated by the wearer of the watch 1 by the action or manipulation of a control means 27 of the watch 1.
  • This control means 27 may be for example a crown rod 27 of the watch 1.
  • the wearer of the watch can therefore initiate the second mode of operation by pressing the rod 27 or by pulling the rod 27.
  • the hour hand 9 becomes slippery and the minute hand indicates the second. Since the time is slippery, the user can accurately know the exact time, even though the minute hand 11 currently indicates the second. After a determined time, the referrals indicate again the hour and the minute.
  • the operating mode automatically changes to the first operating mode, which is the normal operating mode.
  • the watch 1 can return to the first mode of operation by another action performed by the user.
  • the wearer of the watch 1 can again control the control means 27.
  • This other action can be an inverted action, that is to say push the crown rod rather than pull it, which is the action performed to activate the second operating mode.
  • the activation of the second mode of operation is not linked to an action performed by the user.
  • the moment to change the operating mode to the second operating mode is related to the end of life detection of the battery 3.
  • the normal operation of the hands can be changed to provide the user with additional information, which he can interpret as the indication of end of life of the battery 3.
  • the state of the watch 1 changes from the first mode of operation to the second mode of operation.
  • the first mode of operation corresponds to a normal operating mode
  • the second mode of operation corresponds to an alternating mode of operation, that is to say, that in this case, it is a question of end of battery life.
  • the hour hand 9 operates in a slippery manner, while the minute hand 11 becomes the second hand making jumps at each predetermined interval.
  • This interval is typically more than one second, for example two, three, four or five seconds or more. It is also possible to increase this interval as the end of life of the battery 3 approaches.
  • several thresholds can be defined and saved in the control circuit 15. If a first threshold has been exceeded, the interval becomes equal to two seconds, whereas if a third threshold has been exceeded, the interval becomes equal to three seconds and so on.
  • the hour hand 9 and the minute hand 11 become superimposed displaying the sliding time. According to a fourth variant, it can be provided in the end of battery operation mode that the minute hand 11 advances in jumps of 5 minutes.
  • the needles may operate differently from their operation explained above.
