This clock has it all - even a Mister Weather whose mood changes depending on the weather (check our other model with a Miss Weather). The clock is much more than a mere alarm clock. It has a barometer which gives you the current weather and the trend for forthcoming weather. It also indicates the temperature, both indoors and outdoors (a transmitter is provided). You will also be advised on the current humidity rate as it is also a hygrometer. And that's not all. The time of sunset and sunrise is displayed as well as the moon phase (with its 12 quarters).The hour, sun and moon data is supplied via radio waves. Just like you listen to the radio, the data is sent from a transmitter in Germany (if you live in Europe) for constant updating.Transmission:Frequency: 868 MHzDistance: 100 meters (in clear view)Dimensions:Clock = 124,3 x 28,4 x 92,5 mmTransmitter = 38,2 x 21,2 x 128,3 mmPower:2 AA batteries for the clock and 2 AA batteries for the transmitterIncluded:Transmitter for outside temperatureManual in 6 languages (English, French, Spanish, Italian, Germand and Dutch)
