"The provisional measures adopted by COMCO are incomprehensible and unacceptable," Swatch said in a statement. "In view of the negative financial repercussions that these decisions will entail, Swatch Group reserves the right to claim damages."

COMCO Director Patrik Ducrey told Reuters the agency would issue a statement on Thursday, but said the approach the agency is taking in this long-running issue allows Swatch and its ETA subsidiary to continue delivering mechanisms to small and medium-sized watchmaking enterprises for now. A final decision is expected by summer 2020, Ducrey added.
