Notes

Centregraph as well as the Zerograph are instruments of very high precision, to calculate intermediary consecutive ti mes, i.e. when it is necessary, in one single operation, to stop, go back to zero and restart the second hand, for either sports use, car racing, motorbyke, bicycle, or even to calculate the production times of manufacturing process.
