The automatic movement is visible through the open case back of the watch. The Dial: As a watch that\'s intention is to serve a practical purpose in the air, it comes as no surprise the dial simple, yet effective. Firstly, a stylised Swiss Army style font has been utilised for the raised Arabic numeral hour markers, each of which have been coated in lume. Similarly, the dauphine style hands offer peerless levels of legibility, as they are also luminescent. A date window replaces the 6 o\'clock mark, likewise the Victorinox logo replaces the 12 o\'clock marker.  The deep blue dial features a subtle guilloche design that forms a loped flange ring around the edge of the dial. In turn this creates a level of depth, that is made more visible through the reheat which is also home to the circular slide rule. Upon closer inspection it becomes apparent that the red 24-hour scale is printed on the rear of the flat sapphire crystal. This makes the 24-hour scale float on top of the dial and actually bisect the date window; this bestows a certain uniqueness on to the watch. The Strap: Furthermore, the blue fabric strap, comes in a typical NATO style, which is a pleasant reminder of the watches air borne roots. The deep blue colouration of is also very compatible with the deep blue colouration of the dial. Even the dashes of red that are present on the dial are visible through hints of red stitching throughout the strap.  The Functions: One of the most impressive features of this timepiece is the Swiss ETA 2892 automatic movement.
