Abstract
In an electronic watch having a body of substantially reduced thickness obtained by having portions of the top surface of the watch extend above the remainder of the top surface, a liquid crystal or other passive display extends into one of the portions of the top surface extending above the remainder of the top surface. In addition to having the top surface of this portion substantially transparent, side walls of the portion are also substantially transparent in order to allow light to enter the display from the sides of the portion as well as its top. The sides may be shaped to concentrate light entering them on the display. Additional light entering the display from the sides of the raised portion enhances visibility of the display substantially, particularly in dim light conditions.
