Abstract: A timepiece including: a dial; a windshield glass having a plurality of curved surfaces that differ from each other in curvature; and a hand disposed between the dial and the windshield glass, wherein the windshield glass includes: a first curved surface having a first curvature and including a center of the windshield glass; a second curved surface disposed adjacent to the first curved surface and having a second curvature larger than the first curvature; and a third curved surface disposed adjacent to the second curved surface and having a third curvature larger than the second curvature, a thickness of the first curved surface and a thickness of the second curved surface are equal, and in plan view, a distal end of the hand is disposed on a center C side of the windshield glass with respect to a boundary between the second curved surface and the third curved surface.
