Claims

[Claims for Utility Model Registration] (1) A power supply section, a reference signal generation section that generates a clock signal, a frequency divider section that divides the frequency of the reference signal into unit times, and a time period that counts pulse signals per unit time. It is equipped with a counter section, a liquid crystal display section that displays the count time, and a timing control circuit section that receives a time data signal emitted from a separate master clock at a timing input terminal and adjusts the time. A liquid crystal display clock with a timing terminal. (2) A liquid crystal display watch with a timing terminal as set forth in claim 1 of the utility model registration claim, in which each part is laminated to form a sheet. (3) A liquid crystal display watch with a timing terminal according to claim 1 of the utility model registration claim, which is formed in a sheet shape that can be attached with adhesive on the back side opposite to the display part.
