Abstract
Abstract A time display apparatus including a display having a digital display portion and a peripheral analog display portion comprised of a plurality of display segments. Display control means is provided for controlling the digits of the digital display and the segments of the analog display. A manual selection mode switch is used to provide at least two separate modes of control including a normal time mode in which the digital display registers hours and the analog display registers minutes, and a count mode in which the digital display registers minutes and the analog display registers seconds. The count mode can be separated into two separate modes, one for counting up and one for counting down. Furthermore, there is provided an alarm mode associated with the normal time mode.
