Offered here is my wonderful all-original vintage Heuer Bundeswehr 1550SG flyback chronograph with the highly coveted 3H/T dial. The 3H symbol indicates that the luminescent material on the numerals is tritium (Hydrogen-3). As this piece is over 50 years old (c. 1970), the tritium is obviously no longer active.The condition is excellent and the lume is creamy with perfectly matching color on all hands and numerals, another rare and highly desirable trait. The dial is flawless. Works perfectly and keeps great time.Watch comes black leather bund strap as well as a green canvas strap from RedRockStraps, made from a Vietnam War-war era canvas bag. Stitching matches the aged lume. Killer strap.A stellar, very clean example. Enjoy...
