ABSTRACT:
A liquid crystal, electrochromic or other electro-optical material is sandwiched between two glass substrates. An electric field is applied to the electro-optical material to display time and other information on a watch. The lower glass substrate is thinner than the upper substrate so as to create clear displays and to enable the manufacture of a thin watch which is also light weight and shock resistant.
