  • Patent number: 5802016
    Abstract: A multifunctional electronic watch of the present invention displays data measured by a built-in atmospheric pressure sensor by means of a small atmospheric pressure pointer and an atmospheric pressure pointer. It is also capable of displaying a differential between the present atmospheric pressure and an atmospheric pressure three hours before by means of an atmospheric pressure tendency pointer. A dial ring attached around a clockface of the watch is formed with an atmospheric pressure scale, on the outer periphery of which is a rotation bezel formed with a height scale. The built-in sensor is accommodated in the watch so as not to project from the rotation bezel of the watch. Accordingly, an electronic watch which has additional functions of indicating environmental data such as atmospheric pressure without complicating the constitution can be realized.

  • Patent number: 5724317
    Abstract: A current measured value measured by sensor is indicated by a measured value pointer. A maximum or minimum value pointer is interlocked with the measured value pointer and moves only in an incremental or decremental direction to indicate the maximum or minimum measured value. Therefore, a current measured value and the maximum or minimum value can be indicated simultaneously by a single drive source.
