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.  While the brand still exists today, it never regained its market position nor visibility that it once had.
