Context: Concord Watch Company is a Swiss luxury goods company that is part of the Movado group that owns Movado, Ebel, ESQ, Coach and Hugo Boss.  Founded in 1908, Concord was purchased in 1970 by the North American Watch Company, which also distributed the Piaget and Corum lines of watches.  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.  While the brand still exists today, it never regained its market position nor visibility that it once had.

The dials, jewels, and hairsprings for the mechanisms were purchased from European watch manufacturers, but all other parts aside from the outside case were produced at the Manistee Watch factory.  Most of the jewels for the watches were from heliotrope garnet and manufactured specifically to the correct dimensions for the Manistee watches in Switzerland.  The first watches made sold for five dollars each.

Peter Stas (born 1963) is a Dutch entrepreneur and author.  In 1988, after he completed his studies in Business Economics at the Erasmus University and worked as Product-Marketing Manager for Royal Philips Electronics, he founded, with his wife Aletta Stas-Bax, the watch company Frédérique Constant.

The Accessible Luxury positioning was the basis of strong growth during the financial crisis when consumers came back more to classical values and accessible prices. E. Howard & Co. was a clock and watch company formed by Edward Howard and Charles Rice in 1858, after the demise of the Boston Watch Company.

Soon afterwards, Howard bought out Rice's interest and thereafter concentrated on high quality watches based on his own unique designs and eccentric production methods.  E. Howard & Co. produced high grade watches, regulators, and marine clocks. The Dakota Watch Company is a retail and service company that specializes in watches and watch accessories.
