The Swiss Competition Commission (COMCO), the countrys competition oversight watchdog, has launched an investigation against the Swatch Group unit ETA Manufacture Horlogere SA Suisse for a potential abuse of a dominant market position. Reports of the investigation appeared on the Commissions website. A pre-investigation indicated signs ETA had abused its dominant position in the market for mechanical clockworks, the Competition Commission said. A Swatch spokeswoman however said she was confident the results of the probe would clear the fog over the Group and re-establish its adherence to ethical business practices.
