The stainless-steel case, water-resistant to 6 bar, has a diameter of 43 millimetres, which creates enough space to integrate the day and date displays into the dial. On the subdial at ‘9 o’clock’, a red seconds hand indicates that the watch is running normally and adds a colourful highlight to the dial. The slate-coloured, glistening metallic dial was chosen as a tribute to the grey fuselage of the plane that gave this watch its name. A soft-iron inner case protects the precision movement against magnetic fields, while the front glass is secured against displacement by sudden drops in pressure. The bezel on the stainless-steel case and two rows of links in the stainless-steel bracelet are mirror polished, which lends this watch a particularly high-quality feel.
