Swatch
The plastic quartz watch that helped the Swiss watch industry out of the quartz crisis; the group, Swatch Group, also owns Omega, Longines, Breguet and Tissot.
The Swiss watch industry had lost much of its market to Japanese quartz watches, and Ernst Thomke and the engineers Elmar Mock and Jacques Müller at ETA developed a cheap quartz watch with few parts. Swatch was launched in 1983.
Nicolas Hayek led the merger of the Swiss watch companies into the Swatch Group, and Swatch made the watch a fashion product with new designs every season. Artists such as Keith Haring made special editions.
