AI-assisted summary
Description from the seller
During the 1970s, Heuer sold many stopwatches such as the Trackmaster and Trackstar — such as this vibrant red Heuer Trackmaster Ref. 8047, a mechanical stopwatch with 1/5 second precision.
The Heuer Trackmaster offered here features a 1/5 second stopwatch with a timeout function, with a 60-minute register with color-coded segments — it was available in black, blue, white, chrome, or the red of this example.
Trackmaster movements are quite accurate and reliable, with a regulation tolerance of ±1.5 seconds per hour when new. The sporty Trackmaster line from Heuer was a deviation from their “professional” stopwatches for industrial and scientific applications, which had high-frequency balance wheels (Calibre 7700 series with a high frequency of 36,000 bph, with a regulation tolerance of 0.5 seconds per hour).
Not many of Heuer’s brightly colored Trackmaster stopwatches have survived in nice condition, and the example offered here is wound and runs like new, with all color-coded bands on the pushers intact (usually the first thing to wear on these Trackmasters).
Heuer launched its Trackmaster line around 1969 and continued selling it into the 1980s. Mechanical stopwatches from Heuer, with one notable exception, were however less emphasized after the early 1980s. Heuer was a pioneer in electronic LCD stopwatches and marketed them aggressively, which ultimately ended mechanical stopwatches such as this Trackmaster.
This Heuer Trackmaster was used for timing lap times on circuits such as Le Mans and Spa-Francorchamps and during races such as the Mille Miglia and the Targa Florio.
Ideal for the enthusiast of Heuer, Porsche, Ferrari, Le Mans, Steve McQueen, Mille Miglia, Targa Florio, etc.
Details
DIAL: Beautiful, nearly new-old-stock signed dial.
CASE: Plastic-coated resin case, dimensions 65.5 mm x 74 mm, in very good condition.
GLASS: Intact glass, no blemishes or scratches.
MOVEMENT: Hand-wound mechanical movement by Heuer.
CROWN / PUSHERS: Undesignated stainless steel crown; matching minute and second reset pushers. The green crown winds the movement and starts the timer, the red button stops it, and the black button returns all hands to zero.
