The France Ebauches 140.1A watch movement features a pin-lever escapement and is specifically designed for the Digitrened models. The calibre designations and features are derived from various incomplete sources, making them less reliable. However, all calibres are only identified as 420 or 420/425, which is not particularly significant. This movement offers manual winding and includes a digital display for minutes and jumping hours. It was in use around 1975.
