An improved electronic watch module structure includes a chassis member having an egg-crate configuration. A substrate having electronic watch components and conductors mounted thereupon has a piezoelectric crystal elememt mounted on it. The substrate is contained by the chassis member. A portion projecting from one of the side walls of the chassis contains a cavity, and the cavity and a portion of the substrate integrally form a hermetically sealed chamber for the piezoelectric crystal element.
