1. A timepiece comprising:
a dial including a scale;
a windshield glass configured to protect the dial and having a plurality of curved surfaces that differ from each other in curvature; and
a hand disposed between the dial and the windshield glass and configured to indicate information other than hours and minutes, 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 windshield glass in a direction normal to the first curved surface and a thickness of the windshield glass in a direction normal to the second curved surface are equal,
in a plan view as viewed in a first direction directed from the dial toward the windshield glass, a distal end of the hand is located closer to the center of the windshield glass than a boundary between the second curved surface and the third curved surface,
a distal end of the scale is located closer to the boundary between the second curved surface and the third curved surface than the distal end of the hand in the plan view, and
a center of the scale in a cross section is located closer to the center of the windshield glass than a boundary between the first curved surface and the second curved surface.
