A combination quartz watch (Caliber 8981) which has multi-information display by twin analogue and has electronic thermometer function using one IC chip has been developed in December 1982. The main features of this watch are discribed in the paper. The main points are as follows : 1. Twin analogue display Twin analogue display using two independent stepping motors has been developed, which is capable to indicate multi-information, i.e. seconds, alarm, dual time, and hour display for stopwatch. 2. Temperature function A low power consumption system for measuring temperature has been achieved by using an unique circuit, and the circuit for combining temperature and time functions has been also developed. By means of these developments, it has been made possible to add the thermometer function and the temperature memory function to the usual function such as normal time, calendar, alarm, dual time, and stopwatch. 3. Information transfer system The instant information transfer system from digital to anologue by pressing the button has been developed.
