ABSTRACT:
A clock includes a dial, a transparent cover plate spaced apart from the dial at a certain interval to define a space between the back face of the cover plate and the front face of the dial, and hands disposed in the space and driven to move relative to the dial to indicate time. Spacers are disposed on the visible portion of the front face of the dial and protrude against the back face of the cover plate such that the spacers are contactable with the back face of the cover plate upon deformation of the dial and the cover plate to maintain a sufficient interval of the space to allow face movement of the hands.
