PURPOSE:To prevent a case and its rear cover from parting from each other simply when an impact, etc. is applied to a watch, by providing a projection which keeps an engaging piece, which joins the case with the rear cover, from coming off. CONSTITUTION:In a corner section of a thin-wall section 2 of a case 1, a notch section 3 is formed, and it fits in with a projection 5a of an engaging piece 5 of a rear cover 4. A come-off stopping projection 1a is formed toward inside by a given distance from the notch section 3, so that the fitting piece 5 is prevented from bending inwardly when an impact is applied onto the case 1 or the rear cover 4. |
