This is an original Heuer Rally Master, it’s a dashboard mounted chronometer with a “Master Time” clock that would be fitted to rally cars to accurately time stages.
Keeping precise timing of rally stages is critical in all forms of rally but particularly in regularity rally, where the driver and co-driver need to cover each stage in a specified time at a specified average speed.
The purpose of having the timing system mounted to the dashboard was so that both the driver and co-driver could see it clearly. The clock/watch on the left shows the time of day and the chronograph on the left is the stage timer.
Both need to be mechanically wound via the top mounted crown, and the chronograph has a stop/start button at the one o’clock position. Both timepieces are mounted to a chromed steel backing plate that would traditionally be mounted in the center-top of the dashboard.
Both of these timepieces are listed as being in good working condition, together as a set they make an essential addition to the dashboard of any period rally car.
This Heuer Rally Master is due to be sold by Bonhams on the 13th of May in Monte Carlo, with a price guide of €5,000 – €7,000 which works out to approximately $5,260 – $7,370 USD.
