The Beta-21 movement was released at the Basel fair in April 1970. It was the product of nearly 10 years of research and development by C.E.H., or Centre Électronique Horloger, a consortium of many Swiss watch firms including Patek Philippe, Rolex, Piaget, I.W.C., Omega and Longines, all of which were interested in developing an electric watch movement. Early quartz models by the C.E.H. firms all share a similar design with their large and generally more rectangular cases. This case shape was necessary to house the large rectangular movement. Today, this early quartz production and design are regarded as one of the most defining periods of the Swiss manufacturing and are extremely sought-after by collectors.
