The 44 mm circular steel case of the Longines Avigation - a contraction of "aviation" and "navigation" – referring to a navigation system invented during the 1920s - has the same diameter as the original one. It houses an L704 self-winding, mechanical calibre which shows the hours, minutes, seconds and date, and has a second time-scale. As in the 1949 model, the movement is encased in a soft iron plate and dome which protect it from the effects of magnetic fields.

The black dial features large white numerals as well as a 24-hour scale in red. The stick hands on the main dial are rhodium-plated and the lozenge-shaped hand on the second time-scale is red. All the hands are coated with Super-LumiNova®. The upper segment of the dial bears a distinctive sign, namely a broad arrow, used in the United Kingdom to denote government property, including military equipment and therefore the watches used by the British army.
