Battery alarm clock manufactured by Eurochron. This alarm clock is self-corrected with the help of a sensor which daily communicates with a satellite and so in this way the alarm always shows us exact time while with the same procedure the alternation of months (e.g. from February to March) and time (winter-summer) is done automatically. The display of the time is digital while on the screen it informs us about the time, day, month, year the time of awakenings, the temperature of the room. Alarms can work every five minutes with the function (snooze).
