Description

  The present invention relates to an analog wristwatch.

  Conventionally, an analog display or digital display clock having an alarm function is known. Furthermore, there are known analog display or digital display watches equipped with a vibration function as an alarm function (see, for example, Patent Documents 1 to 3). In order to set the notification time and the like in the alarm function, a complicated guide mechanism is required (for example, see Patent Documents 4 and 5). If there was a mechanism such as a reference hand, the design of the analog watch was limited.

  In addition, in the digital display alarm mechanism using the LCD, it is easy to incorporate the reference function into the digital drive circuit. However, since a digital display is required, this is also very limited in design.

  Some use an acoustic alarm instead of vibration. This is a simple structure by simply adding a piezoelectric element to the back cover. However, there is a drawback that the sound is loud and the place of use is limited.

  Patent Document 6 discloses a timepiece with a vibration function using an analog timepiece and a digital display mechanism using LEDs. Patent Document 7 discloses an analog timepiece having an external illumination / charger function.

  In recent years, there has been an increasing demand for high-performance watches with digital display mechanisms using LEDs. However, simply adding a function has led to an increase in the size of the watch module with the increase in the number of electronic boards. Situations where it is difficult to realize the size have occurred.
