  • Patent number: 9740171
    Abstract: An electronic timepiece has a plurality of modes and includes a plurality of indicating hands including a first indicating hand as a mode hand that indicates each mode, an operation section that allows mode switching operation that instructs switching among the modes, and a display control section that moves the plurality of indicating hands to be moved on the basis of the mode switching operation in such a way that periods for which the plurality of indicating hands move in high-speed advance action do not overlap with one another. The display control section first moves the first indicating hand among the plurality of indicating hands.

  • Patent number: 7009915
    Abstract: The present invention includes a dual display watch module comprising a watch face with selectively changing backgrounds which is capable of displaying the time of day using an analog display superimposed over the color-changing watch face thereby creating unique optical effects and patterns and which has a significantly reduced overall thickness. The invention includes a novel configuration of the internal components of the timepiece resulting in a significant reduction in the thickness of the subject timepiece, thereby enhancing the comfort of the individual wearing the timepiece. The novel configuration comprises positioning two smaller sized batteries in the same spatial plane as the PCB and analog watch movement instead of the conventional stacked assembly arrangement whereby a larger battery is placed directly behind the PCB. This allows for an overall thinner movement, thereby resulting in a significantly thinner watch without detracting from the functionality of the watch.

    Abstract: A pointer electronic timepiece (1) has a plurality of step motors, a plurality of pointers (11 to 18), and a plurality of external operation members of a winding crown (5) and buttons (6, 7). The pointer to be adjusted is selected from the plurality of pointers (15 to 18) by operating one of the buttons (6) while drawing out the winding crown (5) to a second stage and the other button (7) is operated to adjust the position of the selected pointer. Since the position of the pointers (15 to 18) driven by three step motors can be adjusted by the two buttons (6, 7), the number of the external operation member is not necessary to be increased even when the pointers (15 to 18), i.e. the step motors, are increased, so that the size and thickness of a movement-holder and cost thereof can be reduced and operability during adjustment can be improved.

    Abstract: An analog clock with a contiguous digital display is driven by radio signals from a WWVB or other time keeping radio station. To avoid using magnetic or optical feedback of the position of the hands of the analog clock if an erroneous time is shown (for example because of replacing the battery), the user of the clock physically resets the digital display to the analog setting (which of course is erroneous). Then an associated microprocessor speeds up or slows down the running of the analog clock until a match is made to the actual radio time.

Polarizer 60c can be rotated about an axis 12 perpendicular to its plane by actuating means 13a, 14, 15, 17 which is accessible from the outside of the casing of the watch. The cell can be made substantially invisible by rotating the movable polarizer 60b in order to position its polarizing plane either parallel or perpendicular to the polarizing plane of the other polarizer 60c, depending on whether the color of the dial around the cell is dark or light respectively.

  • Patent number: 4396294
    Abstract: In an electronic timepiece equipped with both an analog display section having time indicating hands and a digital display section, a time correction system is provided whereby correction of both the analog and digital time displays can be performed by rotation of a crown, with the directions of rotation of the crown for time data incrementation and decrementation being identical both for analog and digital display correction. Selection of either analog time correction or digital time correction is performed simply by pulling the crown out to either of two axial positions. Correction of both analog and digital time display information is thereby simplified and made more rapid, while the number of external operating members is reduced.

  • Patent number: 4355380
    Abstract: An electronic timepiece with hands 1, 2 has a plurality of auxiliary digital displays 5, 6 and 7 for indicating the same parameter, e.g., the day of the month. Only the digital display not interfering, at a given moment, with the analog time display is activated by a control circuit which decodes which of three sectors a, b and c are occupied by the hands. The display in the unoccupied sector, or one of the two unoccupied sectors, is always selected.

  • Patent number: 4335453
    Abstract: In an electronic watch the indication of the time (hours, minutes and possibly seconds) is given in analog form by means of a first passive electro-optic display cell. The display segments of this first display cell are arranged radially with respect to a central point, and the activated segments thereof have the appearance of the conventional hands of an analog watch. The watch comprises a second passive electro-optic display cell furnishing information in digital form, for example indicating the day of the week and the date. So that only the second cell need be provided with an illuminating device, the watch comprises a selector which is manually operable by means of a push-button which, when it is operated, causes the time to be displayed by the second cell at the same time as the illuminating device thereof is operated. This arrangement enables the user to know the time in the dark without it being necessary to provide the first cell with an illuminating device.

  • Patent number: 4320484
    Abstract: A simultaneous analog digital timepiece display comprises two superposed passive electro-optical cells one of which provides analog information and the other digital information. The timepiece is arranged and adapted such that the two types of information displayed are never directly superimposed. Such result is obtained through the provision of three zones for the digital display cell wherein one only of said zones is activated at any one time, such activated zone being chosen so as not to coincide with the position of the analog display hands.

    Abstract: An electronic timepiece is arranged to give an audible time signal indicative of the current time when a user operates an externally manually operable switch means. The operation of the switch means causes a signal emitting means responsive to information relating to the current time to emit a time signal which preferably includes a portion representing a zone within which the current time lies, and a further portion indicative of the current unit of time within the zone. In a preferred embodiment, the signal comprises two parts, one indicating the current hour and the other indicating the current minute.

  • Patent number: 4280209
    Abstract: An electronic timepiece having an analog time display and a digital alarm setting system for actuating an alarm at a preset time. The timepiece includes a high-frequency time base whose output is applied to a frequency converter yielding low frequency timing pulses, these being applied to a motor for driving the hour and minute hands through a gear train. The alarm setting system includes an electro-optical digital display whose electronic actuator responds to the same timing pulses to provide a digital display concurrent with the analog display, and a microprocessor associated with a data memory adapted to store the digital value of any selected time setting. The microprocessor compares the existing time expressed as digital data with the stored digital value to produce a representative output signal when the existing value is coincident with the stored value. The output signal acts to trigger an alarm generator to produce an alarm for a predetermined period.
