ABSTRACT:
An electromechanical wristwatch is described with the particular characteristic of being readable both by sight or by touch in that the hours and minutes are indicated in two square areas. In each of these areas are four cursors which, by means of electrical impulses, which come out of or go back into the case. Said reading by touch can thus be interpreted by means of a series of combinations of the said cursors, which permit the time to be determined with an interval of five minutes.
