In the 1960s and 1970s, Fortis watches looked so colorful and were also so open to the use of plastic that they even could be subsequently classified as forerunners of the Swatch watch. There were models like the Flipper and the Logo, where the plastic case and bracelets could almost arbitrarily combined with colored dials.
