Abstract

The timepiece includes in addition to the hours and minutes hands a calendar mechanism comprising at least one date ring on which is placed an index. The dial includes an annular zone of transparent material through which said ring appears. In a preferred version of the invention the data indications are borne by one of the surfaces of the transparent zone. If the colors of such indications and of the ring are the same and the color of the index different from that of the indications all indications except one will be concealed-that behind which is found the index.
