PROBLEM TO BE SOLVED: To provide a display mechanism of a moon phase for a wrist watch, which is simple, inexpensive, which has a small number of components, and which can be easily produced.SOLUTION: A display mechanism of a moon phase has an input pinion 11 which rotates by three times or twice for 24 hours, and drives a drive pinion 13 having 19 teeth or 29 teeth. The drive pinion 13 drives a lower side wheel 15 of the 59 teeth for supporting a moon disk having two color identified drawings comprising a bright area and an empty area of at least one background, and drives an upper side wheel 14 of 57 teeth or 58 teeth coaxial to the lower side wheel 15. The upper side wheel 14 has an empty disk which rotates by once for one day and has a drawing of the sun, an opening 16 is formed on a side opposite to the sun, and through the opening 16, a part of a moon disk indicating a current appearance of the moon, is visible.SELECTED DRAWING: Figure 4 【課題】単純であり、経済的であり、部品の数が少なく、製造が複雑ではないような、腕時計用の月の相のディスプレー機構を提供する。【解決手段】月の相のディスプレー機構は、２４時間当たり３回転又は２回転し、それぞれ１９歯又は２９歯の駆動ピニオン１３を駆動する入力ピニオン１１を有する。この駆動ピニオン１３は、明るくされた領域及び少なくとも１つの背景の空領域を有する２つの色分けされた描写を有する月ディスクを支える５９歯の下側車１５を駆動し、また、この下側車１５と同軸な５７歯又は５８歯の上側車１４を駆動する。この上側車１４は、１日当たり１回転し、太陽の描写を備えた空ディスクを有し、この太陽の反対側に開口１６が形成されており、この開口１６を通して、月の現在の外観を示す月ディスクの一部が見える。【選択図】図４
