Concord actually made a spot in their history back in 1908 when the company opened one of the first branches in New York City. And in 1968 it was named as being the sixth most popular brand in America.
However, they made their mark a few years before that in 1945 when the then President Harry Truman had given Concord watches to Winston Churchill and Stalin. This was done as a sign of consolidation of relationships between the three of them. In 1969 the then Concord company was bought by G. Greenberg from North American Watch Corporation. The North American Watch Corporation also known as Waltham Watch Company produced roughly 40 million watch products between 1850 and 1957!
In 1979 they broke yet another history record as producing the Delirium which is actually one of the worlds thinnest quartz watches - a mere 1.98mm and in 1986 they marked their first watch in their sports edition by introducing the Saratoga. In 1998 the company celebrated its 90 year anniversary by issuing the new Delirium and Impresario Minute Repeater which are two of their most sought after watches ever - only 90 pieces in all were made.
These days, Concord brands are still considered as being some of the great quality made watches in the business!
