In Olympic sports, hundredths of a second can be the difference between staying and going home.

And now, state-of-the-art technology is making hockey more accurate, as well.

Inside the Olympic hockey venue, CEO Alain Zobrist and his team at Omega are spending a lot of time making the game more accurate by replacing the whistle with a high-tech one.

The sound is transformed into an electronic signal, stopping the clock faster, keeping seconds from being wasted.

“It stops the running the time immediately in less than 100 milliseconds and over an average game, we gain 42 seconds,” Zobrist said.

For the first time, players are also wearing motion sensors that track everything an athlete does on the ice, so people can see it while watching from home. Also for the first time, referees will be connected so fans can hear them from home on TV, as well.
