NOTES: Bundes Wehr means ‘Federal Defence’ in German. This military flyback chronograph, introduced by Heuer in 1968, is an iconic vintage wristwatch associated with the German military. This watch has the word “Bundeswehr” followed by the military serial number, indicating the region it was issued, engraved on the back as they were only issued to German servicemen from 1968 until the late 1970′s. The ‘3H’ red symbol found on the dial signifies ‘tritium’ as it is found in the luminous indexes and on the dial and hands. This symbol served to warn servicemen to avoid radioactive sensitive areas.
Since this is a flyback chronograph, the mechanism can be reset while it is still running, making it particularly useful for servicemen timing consecutive short interval events. The beauty in this mechanism is when the reset button is pressed, the flyback lever lifts the coupling clutch from the chronograph center wheel allowing the mechanism to reset.
