Abstract
A timepiece is equipped with a movement, a timepiece case accommodating the movement, and a hollow tubular structure portion having a connection proximal portion directly or indirectly in contact with the movement. The hollow tubular structure portion is formed such that a space defined between itself and the timepiece case is hermetically sealed. The inner space of the hollow tubular structure portion communicates with the exterior of the timepiece case via an external opening of the timepiece case. The timepiece can secure a sufficient waterproof performance and can transmit sound from a sound source efficiently to the exterior.
