Abstract: A timepiece includes a dial plate, and a solar battery which is disposed on a rear side of the dial plate. The dial plate is provided with grooves or ridges. The grooves or the ridges have portions where inclination angles with regard to a normal line of the dial plate are different, and due to this, light which is transmitted through the dial plate is incident from a plurality of directions with angles which are different with regard to the solar battery.

Abstract: To provide a timepiece which is easy to produce, a timepiece includes a case forming a ring shape; a back cover fitted to a back side of the case, and a fixing member forming a ring shape running along the circumferential direction of an inner peripheral part of the case, and having a fixing function for fixing the back cover to the case. The case is harder than the fixing member. The fixing member is disposed between the case and the back cover, and is compressed and deformed therebetween, thereby making it possible to fulfill the fixing function.

Abstract: A timepiece includes a dial plate and a solar battery which is disposed on a rear surface side of the dial plate. The dial plate has an area larger than the solar battery. The solar battery is encompassed by the dial plate in a planar view. The dial plate is provided with grooves or ridges which have a function of condensing incident light.

Abstract: A dial assembly held within a timepiece case together with a movement for which the hour hand and minute hand are supported to be able to rotate is provided. The movement supports at least one miniature hand to be able to rotate at a position different from the hour hand and minute hand. The dial assembly comprising includes a first dial that is light transmissive, a second dial arranged on the back surface side of the first dial, and at last one spacer forming a ring shape arranged between the first dial and the second dial. The miniature hand rotates within a space enclosed by the first dial, the second dial, and the spacer.

Abstract: presenting A timepiece faceplate includes a plate-shaped member provided on one surface with a ridge having a function for reflecting and scattering incident light, which is made of a material having optical transmission properties; and a layer in which numerous powder particles having a function for reflecting light are dispersed and which faces a surface opposite from the surface on which the ridge of the plate-shaped member is provided. The plate-shaped member and the layer of the timepiece faceplate are superimposed when viewed from above.

Abstract: A dial assembly is held inside a timepiece case together with a movement that supports an hour hand and minute hand to be able to rotate. The dial assembly includes a plate shaped dial, and at least one decorative structure having a decorative member which can be visually recognized from the front side of the dial and a support member by which the decorative member is supported on the dial. The dial has a fixing member for fixing the decorative member, which is constituted with through holes that pierce the dial in the thickness direction. In a state in which the decorative member and the support member are assembled, the decorative structure is inserted in the fixing part from the front side of the dial to be fixed.

Abstract: To provide a cover glass that is easy to manufacture and a timepiece equipped with the cover glass, a cover glass is a member used by being attached to a body of a timepiece. This cover glass has a plate-like form and includes a cover glass main body and a spacer. The cover glass main body has a transparent quality, and the spacer has a transparent quality, is joined to a back surface of the cover glass main body, and has a ring shape that follows along an edge portion of the cover glass main body. In this cover glass, the cover glass main body and the spacer can be made of the same material or of different materials.

Abstract: To provide a timepiece faceplate presenting a furred appearance that has been impossible to achieve in the past, and to provide a timepiece provided with the timepiece faceplate. A timepiece faceplate 1 of the invention comprises a plate-shaped member 11 provided on one surface 111 with a ridge 113 having a function for reflecting and scattering incident light, the plate-shaped member 11 made of a material having optical transmission properties; and a layer 12 in which numerous powder particles 121 having a function for reflecting light are dispersed on a surface 112 opposite from the surface 111 on which the ridge 113 of the plate-shaped member 11 is provided. The plate-shaped member 11 and the layer 12 of the timepiece faceplate 1 are superimposed when viewed from above.

Abstract: There is provided a button capable of entry and exit with respect to a base. The button has a button member, ring member, lock member, and fixed member. The button member has a shaft portion mounted in a manner that allows entry and exit with respect to the base, and an expanded-diameter portion with a shaft diameter that is larger than the diameter of the shaft portion. The ring member accommodates the shaft portion and can rotate about the axial center of the shaft portion. The lock member moves along the axial center between the ring member and the shaft portion due to the rotation of the ring member, and restricts the entry and exit action of the button member by coming into contact with the expanded-diameter portion of the button member. The fixed member is fixed to the base and stops the ring member to restrict the movement of the ring member along the axial center.
