Offered here is an authentic Heuer Trackmaster mechanical stopwatch, a highly regarded Swiss-made precision timer produced during the golden era of professional chronometry, circa 1960s–1970s. The Trackmaster line was widely used in athletics, motorsport, laboratories, and industrial timing, reflecting Heuer’s long-standing reputation as the world leader in professional stopwatches. This example features the distinctive blue composite case, an instantly recognizable design associated with Heuer’s technical instruments of the period. The white dial is clean and highly legible, with bold Arabic numerals, red outer minute track, and a subsidiary minute counter at 12 o’clock. The stopwatch is manually wound and operated via the original crown and pushers, showcasing classic Swiss mechanical engineering. Importantly, this piece is accompanied by its original Heuer cardboard box, marked “World leader in stopwatches – since 1860 – Swiss”, significantly enhancing its collectability and originality.
