The Bundeswehr was formed in 1955 as the United Armed Forces of Germany, which during this time, was in defense of West Germany. As the spearhead of the nato forces and sitting on the proverbial borders of the Soviet Union, the Bundeswehr was one of the most modern and well-equipped armed forces of its time. The Heuer Bundeswehr 1550 sg was one such piece of equipment that saw production in the period from 1955 to 1990, which was the year Germany was reunified and the Bundeswehr restructured.
the watch was created to be a tool of the pilot of the Bundeswehr, but research shows that it was also worn by other branches of the service. Men in ground forces such as artillery were also said to wear 1550 sg.
Probably due to different factories in different time periods producing the parts for the watch, particularly the dials, the Bundeswehr chronograph can now be found in various dial configurations. There are 5 main dial configurations:

the "classic 3H / t"; it has a red 3H symbol appearing just below the center of the dial and a small "t" appearing just above "6".
the "3H-only"; it has a red 3H symbol that appears just below the center.
the "just t"; it has a little "t" that appears just above "6".
the "clean"; it has no markings other than the "Heuer" logo.
the "sternzeit"; formulated with the sternzeit reguliert markings just below the center of the dial.

The stainless steel case has a gunmetal color with a brushed finish. It measures 42 mm in diameter and 13 mm in thickness. The case construction is mostly traditional, in the style of the first chronograph wristwatches. It consists of two pieces, with a 4 screw back design. the buttons are pump and have a good operating mechanism. The large unmarked crown also makes it easy to wrap and adjust.

This watch has both a flyback chronograph function and a hacking mechanism. It uses the hand-wound Valjoux 230 flyback chronograph movement that beats at 18,000 mph and has a power reserve of about 48 hours.

In a regular chronograph calibre, the chronograph mechanism must be stopped before it can be reset. In a flyback chronograph, the mechanism can be reset while it is still running, making it particularly useful for synchronizing consecutive short-duration events. This is made possible by the addition of an additional lever in the chronograph mechanism. When the reset button is pressed, the flyback lever lifts the coupling clutch off the central chronograph wheel allowing the mechanism to be reset.
