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 IWC IW377719 has an automatic movement with 44 hours of power reserve, Grey dial colour and Steel bracelet.
