摘要

The invention concerns an electronic and mechanical device incorporated in watches and wrist bands enabling double worldwide representation of solar calendar and phases of the moon. The first, pictured on a circular LCD display panel, displays all year round, the day and night evolution at standard time or winter time; the second, digitally displayed, only the standard sunset time. The mechanical part adapts the phases of the moon to the two hemispheres.
