Notes

The watch must have been destined for measuring very high speeds since a second dial was intended just for calculating speeds over 180 km/h. At the time such speeds were encountered in scientific experiments and in aviation. The main dial was for measuring sailing races, running and car races (Bugatti could go 120 km/h), the back dial was for aviation and scientific measurements.
