The Olympic timekeepers keeping the Games on track

In an Olympic event as fast as downhill skiing or speed skating, the margin between winners and losers can be measured by thousandths of a second.

Careers are “forever altered by that tiny difference”, said NBC News. There is a “baseline expectation” that “every result must be perfect”. And that is “determined by the most important team at the Olympics you don’t know about”: the Games’ timekeepers.

‘Tiny calibrations of a split second’

Swiss watchmaker Omega has been the official timekeeper of every Olympic event for nearly 100 years, initially chosen for the 1932 Los Angeles games as it was the only watch brand capable of providing accurate timing to the nearest tenth of a second.

The company dispatched one “intrepid watchmaker” from its Swiss headquarters with 30 high-precision stopwatches in his suitcase, said The Times. “Each night he would take the stopwatches back to his hotel room and recalibrate them, before handing them back to race officials the next morning.”

Omega now provides the timing for all 116 events, including (for the first time this year) ski mountaineering. The intervening years have, of course, seen “extraordinary technical developments”. Omega arrived in Paris for the 2024 Summer Games with “the most advanced tech it has ever delivered”: 350 tonnes of equipment, including 200km of cables, hundreds of scoreboards, and 550 professional timekeepers. The days of a ribbon breaking across a winning runner’s chest are “long gone”. World records are now regularly broken; margins of winning come down to “tiny calibrations of a split second”.

No margin for error

“We’ve come quite a long way since one watchmaker travelled” from Bienne, said Forbes. Planning for the current Milano-Cortina Games began three years ago, with more than 300 timekeepers and 130 tons of equipment dedicated to the Games, including high-speed cameras that can capture up to 40,000 digital images per second. This information can then be fed into AI models specifically programmed for each sport to produce graphic recreations of every movement. Judges have access to that data instantly – and this year, for the first time, so will viewers.

“For a person who is following action sports not on TV every weekend but once every four years, it’s very difficult to understand the differences in performances,” said Alain Zobrist, chief executive of Omega Timing. We are “trying to explain where these differences are and how these differences may impact the judging.”

But the final call is still human: an operator looks at a monitor with footage from the finish-line cameras, and “manually places a cursor where the athlete crosses the finish”, said NBC News.

“What you cannot learn is the pressure that comes with it when you operate it,” said Zobrist. “We take a lot of pride doing it, but it also humbles us a lot.” Billions of people are watching and waiting for the results to appear. An operator knows they’re “not allowed” to make mistakes; “as soon as you push that enter button, the result is released and public”.

Olympic time-keeping has grown so complex that preparations are well underway for the return of the games to Los Angeles in 2028. The only device still used that hasn’t changed since 1932? “A metal bell is still rung by hand to mark a race’s last lap.”
