European Watch Clock and Jewellery Fair 1982 BF 301
This alarm watch features a new quartz module ESA 926.311 111/2 ’ with analogue display of hours, minutes and selected alarm time; with calendar. Its 3- position crown does it all simply and easily: alarm set or shut off, alarm signal stopped, alarm time selection, date calendar setting, time setting, battery check. Alarm beep (about 20 seconds’ duration at 72 dB) produced by piezo-ceramic resonator. Extra-slim movement - 3,6 mm - is the key to design of elegant case styles. (MICROMA “MemoQuartz”)
