PURPOSE:To store automatically both maximum and minimum temperatures and the time to an electronic watch, by combining a detecting means to detect both maximum and minimum temperatures, a data storing means and a detected time storing means and performing detection and storage by means of a measurement instruction signal which is generated with a fixed cycle. CONSTITUTION:A timepiece circuit 1 containing a crystal oscillator delivers a present time data signal D1 and a measurement instruction signal P0 which is produced with a fixed cycle. A timing generating circuit 2 works in response to the signal P0 and an operation P1. A temperature measuring means 3 includes a temperature oscillator 3a which changes its oscillating frequency by the temperature conditions. The maximum and minimum temperature detecting means 5 and 8 are connected to the means 3. Then maximum temperature detection data and time storing means 4 and 6 or minimum temperature detection data and time storing means 7 and 9 work to perform these storing operations. The contents of storage are selectively displayed at a display 10. Thus it is possible to detect automatically the data on both maximum and minimum temperatures which vary as the time elapses. |
