Seiko Designer Wins Medal from Japanese Government
Watch designer Nouhiro Kosugi was awarded a Medal with Yellow Ribbon, which goes to individuals who become public role models through diligence and perseverance.

Tokyo--Watch designer Nouhiro Kosugi, a longtime leader in Seiko’s development efforts, has been awarded the Medal with Yellow Ribbon by the government of Japan.
This award is given to individuals who, through their diligence and perseverance in their professional activities, become public role models, the brand said in a news release announcing Kosgui’s award.
Kosugi has been a leader in watch design development for more than 40 years, and is best known for his luxury watch designs, which represent a distinctively Japanese sense of beauty, Seiko said.
He has won three Good Design Awards for his work with the brand’s Luxe collections. Possibly his most famous achievement, however, is designing the Grand Seiko Hi-Beat 36000 GMT, which won the “Petite Aiguille” prize at the 2014 Grand Prix d’Horlogerie de Genève, the equivalent of the Academy Awards of watchmaking.
More recently, Kosugi helped to design the Credor Fugaku Tourbillon Limited Edition, which was unveiled at Baselworld earlier this year and is the brand’s first tourbillon.
To create this timepiece, he worked with Seiko’s master craftsmen Satoshi Hiraga, metal engraver Kiyoshi Terui and lacquer artist Isshu Tamura.
