O que é um Cronômetro?

Um cronômetro (contador ou cronógrafo) é um relógio que mede o intervalo de tempo decorrido desde quando foi ativado até o momento em que foi desativado.

Quando surgiu o Cronômetro?

Os cronômetros surgiram na década de 1860, com contribuições das empresas Seiko e Tag Heuer.

Hoje as empresas concentram seus esforços em desenvolver cronômetros cada vez mais precisos na marcação de pequenos intervalos de tempo.
