Omega, prior to 1894, was Louis Brandt & Frère – a watch company based in Bienne, which produced watches, prior to the adoption of the Omega name, under a variety of different brand names, including Jura, Patria, and Helvetia. In 1894, however, the company began production of a movement that was to change watchmaking history, and whose name was to become established as one of the most important in the history of Swiss watchmaking. This movement was the Omega caliber – a 19‴ (19 ligne; for more info on the ligne as a unit of measurement, check out our story from last year) with several important characteristics. It was one of the very first Swiss watch movements that was designed to be produced on an industrial scale, on a recognizably modern production line, with, most significantly, completely interchangeable components.
