Sebring, Master-Time, and Monte-Carlo | A trio of dashboard mounted timers combining two dashboard chronographs and clock, Circa 1965

While the Super Autavia and Rally Master did good duty as dashboard mounted chronographs for many, there were times when more times had to be tracked and recorded. For those with such as need Heuer offered triple and quadruple plates to mount as many timers are required in any configuration that was convenient.

Where it was four Master Time clocks to track different time zones on an office design, three Monte Carlo timers to track splits at a track for different drivers, all were possible. One of the most popular lineups, as featured in the Heuer advertisements of the period was a central Master Time clock to follow overall time, flanked by two chronographs.

Early on this would have been the Auto-Rallye, but as the Monte-Carlo and Sebring models became available, these proved to be ideal configurations. As composed here, the set can track three times, thanks to the split-second function of the Sebring, meaning it could be used on the pit wall, or in-car to track stage or sector times.

When combined with a Haldex tribometer and a Curta “pepper grinder” mechanical calculator navigators in rally cars could complete time/speed/distance calculations, vital information on regularity events where the times are checkpoints had to be carefully tracked. With the rise in popularity of such events today, from the revivals of legendary courses such as Tour Auto and the Targa Florio, to more modern events, the triple set of timers represents perhaps the ultimate configuration for in car timing.
