1916 Tag Heuer : a chronology Mikrograph and Microsplit: accurate to 1/100th of a second

TAG Heuer invents the 'Mikrograph' and the 'Microsplit', the world's first sports stopwatches with a precision of 1/100th of a second. The 'Microsplit' version can measure two events simultaneously thanks to its fly-back hand. These new developments revolutionized science, industry and watchmaking, and made TAG Heuer the natural choice as the official supplier of timing instruments for the 1920 Olympic Games.
