The Extract from the Archives, dated March 2020, mentioned that this watch was invoiced on October 27, 1930, to the Longines agent, Maison Ostersetzer, Italy.
The watch must have been destined for measuring very high speeds since a second dial was intended just for calculating speeds over 240 km / h. At the time such speeds were encountered in scientific experiments and in aviation (a Bugatti could go to 120 km / h). The main dial was for measuring sailing races, running and car races, the reverse dial was for aviation and scientific measurements.
