Part of the "rally computer"...very accurate for speed and distance. With a stop-watch for timing, makes your "rally stage" computations very accurate. "State of the art" for rallying, at the time...
Remember, this was l-o-n-g before current computer technology...
In a TSD rally with a multitude of checkpoints, over 4000 miles as this one was run, a winning time within a minute was possible/expected! And that took very accurate distance-speed calculations to accomplish.
