Michael Wunderman, who has overseen the brand's development, said he was moving back to California to be closer to his family after seven years in Europe.
The son of Corum chairman and owner Severin Wunderman, Michael Wunderman now will preside over the brand's distribution in North America, succeeding Stacie Orloff as president of Corum USA. He will continue to work on the brand's creative committee and also remains on the executive board as vice chairman alongside his father.
"The direction in which the brand is now moving is clearly defined," said Michael Wunderman. "Our operational structure is strong and I no longer need to be involved in the day-to-day [running] of the company."
Parallel to Wunderman's change in position, Johnny Wizman has been promoted to vice president of sales. Wizman is Severin Wunderman's nephew and has been working in the business for the last decade.
Meanwhile, Scott Nichols, formerly chief financial officer of Corum's global operations, has been promoted to vice president of operations of Corum USA.
Antonio Calce, general manager of Montres Corum, will continue to oversee operations at the company's headquarters in La Chaux-de-Fonds, Switzerland.
