He named his invention the Chronograph. It was a mechanical device that could record time on a piece of paper.

Semikrograph
The Semikrograph, which was created by TAG HEUER later on in the same year, was a revolutionary stopwatch that was able to count down two different sets of time on two different watch faces. The fragments of time were measured in 1/50th of a second time intervals. (exact date unknown) http://blog.onlineclock.net/history-of-stopwatches/ -

Digitimer
after the 1970's the mechanical stopwatch was soon overtaken by the digital stopwatch. Invented by the American watch company Cox Electronic Systems, the digitimer was an advanced digital timer that was able to record times as precise as 1/1000th of a second. It was used mostly in sporting events that required precise time measurements. (exact date is unknown) http://blog.onlineclock.net/history-of-stopwatches/ -
Accusplit digital stopwatch
