Greg B. Thumm.

Mr. Thumm served as president of Bulova Corporation, with full profit-and-loss responsibility, reporting to the chairman and board of its Japanese parent, Citizen Holdings. He moved the company’s headquarters to the Empire State Building, consolidated its European subsidiary into a single business with shared services, reorganized its Hong Kong office under new management, and led a rebranding that covered the logo, the packaging, and the watch designs.

Before Bulova, he was senior vice president of watch product at Fossil, with top-line authority over product design for Fossil, Armani Exchange, Michael Kors, Marc Jacobs, Adidas, DKNY, and Diesel. He rebuilt Fossil’s product development teams in Dallas and Hong Kong, moved its outside suppliers onto three-dimensional design, cut design development and mass-production lead times by a third, and put the company’s assemblers and component vendors on a balanced scorecard. He also helped consolidate Fossil’s assembly operations in Hong Kong and its component factories in China, and contributed to the invention of two watch movements.

At Geneva Watch Group, from 1995 to 2004, he ran product for the company’s house brands and licenses, helped win the Kenneth Cole license and launch its first watch collection in 1997, and created the first Tommy Bahama watch brand two years later. Earlier, as vice president of watch product at Gruen Marketing Corporation, he ran the design cycle for Gruen, Bill Blass, Pierre Cardin, Oscar de la Renta, and Geoffrey Beene watches. Before that, he held product development and technical roles at Chung Nam Watch Company and Panther Manufacturing in Hong Kong.

In 2019, Mr. Thumm and his son founded Thümm & Co., a direct-to-consumer watch brand based in Warren, Ohio. He trained as a watchmaker at Bowman Technical School in Lancaster, Pennsylvania, and is a past board member of Jewelers for Children and the American Watch Association.
