Abstract: A timepiece with a calendar function. The timepiece includes a main plate (19) has a plurality of holes (76) arranged along the outer periphery of a ring-like day indicator (26) when the same is disposed concentrically on the main plate. When positioned, the day indicator (26) is disposed substantially concentrically with the main plate (19). When a plurality of guide pins (77) are inserted into the plurality of holes (76), respectively, in the main plate 19, the guide pins (77) cooperate to come into contact with the outer periphery of the day indicator to adjust the position of the day indicator (26) in radial directions, thereby positioning the day indicator exactly concentrically with and on the main plate (19) (FIG. 18).

Abstract: A light emission and display device (for example, timepiece module) comprising an ultraviolet ray emitting element that emits ultraviolet rays, light emission areas that react to the ultraviolet rays to thereby emit the corresponding colored lights, and a pair of legs that connect in a stabilized manner the ultraviolet ray emitting element and a connection terminal of a circuit board in the light emission and display device. Each leg has a bend for adjusting the length and a bend angle of the leg between the ultraviolet ray emitting element and the connection terminal (FIG. 19).

Abstract: In a time-setting mechanism for an analog time-piece, when an operation member is moved in its axial direction, a pinion provided on the operation member is brought into mesh with a gear which is normally rotated in an interlocked relation to hands. When the operation member is turned in this state, the torque thereof is transmitted via the pinion and gear to the hands for time-setting. The pinion and gear are made of synthetic resins, and the pinion is made of a resin material having higher flexibility than the resin material of the gear.

Abstract: Synthetic resin shaft and gear portions are molded to be capable of slipping each other. During a normal timepiece operation, the shaft and gear portions are integrally rotated. During a hand setting operation, the shaft portion is rotated with slip on the gear portion. In this slip structure of a timepiece, at least one of the shaft and gear portions is formed of an oil-containing resin material.
