European Watch Clock and Jewellery Fair 1978 BF 387
Liquid crystals give you the time in Roman numerals (!) as the solid-state watch moves into the luxury class. This singularly opulent design has a case only 4.9 mm thick (the module inside is itself a mere 2.85 mm...) but in solid 18K gold and set with 78 diamonds. Too bad Louis XIV didn’t know about LC technology. (PAOLO SPADINI)
