Dubey & Schaldenbrand is a luxury watch company dating back to 1946 and named after founders Georges Dubey and René Schaldenbrand.
 In 1995, the revival of Dubey & Schaldenbrand started as a homage to the past with Cinette Robert deciding to open her vault containing her fabulous old movement collection.
 (During the 1970s and early 1980s, Cinette Robert was one of the few visionaries that toured all manufacturers in order to purchase watch movements and components.
 Recasing each movement according to the era when it was created, the Dubey & Schaldenbrand designs rapidly found a niche with collectors.

 From the late 1970s to the late 1980s, Concord produced what would become some of the most marketed and respected luxury quartz watches on the market.
 Concord watches became recognized in large cities as status symbols and were noted for their innovation and design.
 Flagship quartz models such as the Concord Centurion and Concord Delirium ranged from $2,000 to $20,000 surpassing the price of base automatic Rolex, Cartier and Omega wristwatches.
 By the 1990s Concord watches fell out of style and grew obsolete amidst the re-branding of the company.
