Abstract

PURPOSE:To prevent crushing of a projection due to a drop shock, by a method wherein a metal sheet is formed in an internal shape of a watch case and said work is used in combination of a middle frame. CONSTITUTION:A plastic middle frame 2, into which a movement is built, is fitted in a watch case 1, and a metal sheet 5 in a given shape is incorporated so that the outer configuration of the metal sheet 5 makes contact with the inner configuration of the watch case while the inner configuration thereof makes contact with an outer configuration of a projection 6 on the middle frame 2.
