Abstract: A timepiece case including: a case; a windshield member, a first portion from among a side surface of the windshield member facing the case; a waterproofing member positioned between the case and the windshield member and configured to waterproof an inside of the case; and an exterior member, wherein: the case has a plurality of protrusions that is provided at respective plurality of portions facing the first portion and protrudes from an inner-wall surface of the case toward the first portion, the plurality of protrusions prescribes a position range for the side surface of the windshield member with respect to the case, and the exterior member faces a second portion that is from among the side surface of the windshield member and differs to the first portion.

Abstract: A timepiece includes: a casing; a light transmission part; a function part; and a glue adhering the light transmission part to the casing. The casing includes: a projection projecting from an inner circumferential surface and extending along a circumferential direction; and a protrusion protruding from the inner circumferential surface and determining a position of the light transmission part. A lateral surface of the light transmission part is adhered to the inner circumferential surface. A peripheral part of a bottom surface of the light transmission part is adhered to a top surface of the projection. An outer circumferential surface of the function part extends along an inner surface of the projection. A space is present in a facing region where the projection faces the function part along the light transmission part. The space is wider in a specific section including the protrusion than in a section different from the specific section.

Abstract: Disclosed is a switching device including: an enclosure that is provided on an outer part of a case and opens toward an outside of the case; a filter arranged in the enclosure; an operation receiver that is arranged on an outer side of the case relative to the filter and includes: a shaft having one end side inserted in an insertion hole provided to extend through from the enclosure toward an inside of the case; and an operation head provided on the other end side of the shaft and arranged at least partially in the enclosure; and a rotation restrictor that restricts rotation of the operation receiver.
