The Amida Digitrend is a manual-wound digital watch; its distinguishing feature is that the time is displayed on the side of the watch rather than on the top, which makes it the perfect watch for drivers. The display on the side is hard to achieve in a mechanical watch, so a prism is used to mirror the display by 90 degrees. The digits on the wheels are in mirror writing and readable in the display through the deflection. The watch uses an Amida pin lever movement calibre 420; the design is described in US Patent 3685283.
