European Watch Clock and Jewellery Fair 1978 R 1054
That’s right: two dials. One for local time, the other for the time zone of your choice: GMT, Mecca time... A useful plus for airline hostesses, travel agents, travellers ... Or simply to keep a neighbouring country’s summer time in mind. All this at an attractively economical price too. (EDEN - Gisiger-Greder)
