Together they are 230 years old. And have just launched their third start-up. Luc Tissot and his two colleagues have developed special contact lenses that measure the internal pressure of the eye fluid. The know-how from precision mechanics is no coincidence. Luc Tissot is a descendant of the same watch dynasty from Le Locle.

Film directed by the Swiss TV channel SRF
