Abstract: The invention concerns with an electronic timepiece provided with digital display means including an elastomeric display element. This element has an uppermost transparent and solid plate which is made of glass or plastic resin material, serving as a solid base member of the element durable to outside mechanical stresses and shocks. The thickness may amount to about 0.2-2 mm, or so. Transparent upper electrodes are provided at the lower surface of the glass or plastic resin plate, these electrodes being shaped and arranged in registration with the display segments of a scheduled display pattern. The thickness may be in the order of 500-2,000 A.

Abstract: The invention resides in an improved time error measuring device or test bench for watches. The device includes a sensing microphone for sensing the stepping movement of the watch under test and in the form of a series of electric signal pulses. It further includes a range selector adapted for selecting a proper range depending upon the thus sensed stepping signal pulse series. Time error measuring means is utilized for detecting occasional time error of the watch by comparing the sensed stepping pulses with a standard clock pulse series and at the precision attributed to a selected measuring range. All these operations may be carried out in a fully automatic manner.
