Abstract
To provide a display device for a timepiece wherein model changes can be easily made with a simple structure in a timepiece with a retro display. In a day display device, an hour wheel, day intermediate wheel, and cam are disposed on the same axis, and a lever and small day indicator are disposed so as to enclose these components, whereby a simple configuration can be achieved. A large space for accommodating the lever can be provided between the substantial center and the peripheral edge of a main plate on which the hour wheel, day intermediate wheel, and cam rotate on the same axis, and various shapes are made possible by freely extending the lever from the substantial middle to the peripheral edge of the main plate. Therefore, it is possible to form first through third gear parts through, and to provide three positions A through C for incorporating the small day indicator. This has merits in that timepieces of different models can thereby be easily manufactured merely by changing the position for incorporating the small day indicator, and there is no need to change the configuration of the movement when the model is changed.
