Concord was founded in Biel in 1908 and built a defining reputation in 1979 with the Delirium, a watch measuring just 1.98 millimetres in thickness that held the record for the thinnest watch ever produced for over three decades. That achievement required the case itself to function as the movement's baseplate. This engineering solution pushed Swiss case-making and movement integration in directions few manufacturers attempted at the time. The brand's later Mariner and C1 collections moved toward sports-watch territory, but the Delirium's record-setting precision remains the reference point most closely associated with the Concord name among collectors today.
