发明名称 Watch with a 24-hour watch face
摘要 A watch having a watch face comprising an analog 12-hour display which displays a 24-hour day in an ambiguous manner using an hour hand and a minute hand, and an additional display which is used to determine the time indicated by the hour and minute hands and has two distinguishable symbols which are visible in said additional display separately from each other and change approximately every 12 hours. The invention is characterized in that the distinguishable symbols are configured as day and night symbols in such a way that they can be unambiguously interpreted as such by anyone and that the change-over from the night symbol to the day symbol occurs at 6 a.m. and the change-over from the day symbol to the night symbol at 6 p.m. either suddenly and precise to the second or over a period of time which can be observed dynamically so that there is never any doubt as to the time being shown.
