Braun GmbH was founded in 1921 by mechanical engineer Max Braun and in Frankfurt. Braun’s early focus was on radio components, which gradually evolved into completely radio sets. Braun eventually expanded into a variety of consumer household appliances, cameras, student learning kits, and watches. The company was owned by Gillette from 1984 until 2007, and is currently a subsidiary of Procter & Gamble. Braun watches have since been produced by other companies under license.
Title Sponsor of Tyrrell Honda
After competing without a main sponsor in 1990, Braun was announced as the title sponsor of the Tyrrell Honda Formula 1 Team for the 1991 season. The Tyrrell 020 was driven by Stefano Modena and Satoru Nakajima, father of Kazuki Nakajima.
The Braun AW20 Tyrrell Honda edition was produced to commemorate the partnership, co-existing in the same era as other quartz racing watches including some Seiko Honda F1 Grand Prix Racing Team and TAG Heuer Formula 1 models. The timepiece features the German company’s Bauhaus style, with “Tyrrell Honda” printed on the dial of an otherwise standard AW20 model.
