To obtain a watch that can prevent deformation of a display board while maintaining the accuracy in positioning a plate-like member.SOLUTION: A watch comprises: a display board 14; a movement 18 that rotatably supports the display board 14 centering the axis in a plate thickness direction and is installed along the axial direction; a straight pin 42 that is erected in the axial direction on the movement 18; an opening 44 that is provided in the display board 14, into which the straight pin 42 is inserted, and has a width reduction part 50 in which the width is reduced toward one direction in the circumferential direction of the axis; and a taper pin 40 as a rotation mechanism that is provided on the movement 18, rotates the display board 14 in the other direction in the circumferential direction, and holds the straight pin 42 in the width reduction part 50, and a round hole 46 as a rotation mechanism that is provided in the display board 14.SELECTED DRAWING: Figure 3 【課題】板状部材の位置決め精度を維持しつつ、表示板の変形を抑制可能な時計を得る。【解決手段】表示板１４と、表示板１４を板厚方向の軸を中心に回転可能に支持すると共に、軸方向に沿って設置されるムーブメント１８と、ムーブメント１８において軸方向に立設するストレートピン４２と、表示板１４に設けられ、ストレートピン４２が挿入されると共に軸の周方向一方側に向かって幅員が減少する幅員減少部５０を有する開口部４４と、表示板１４を周方向他方側に回転させ、幅員減少部５０でストレートピン４２を挟持させる回転機構としてのテーパーピン４０がムーブメント１８に設けられ、及び回転機構としての丸孔４６が表示板１４に設けられている。【選択図】図３
