In 1950, a gold medal could be decided by whichever official had the fastest thumb. In 2026, as the Commonwealth Games head to Glasgow, the difference between gold and silver may be smaller than the width of a fingernail, and a machine will catch it. Seventy-four nations and territories. Thousands of Athletes. One clock.

At the Commonwealth Games, time is the only judge that treats every competitor equally. Spectators watch the race. They watch the scoreboard. What they rarely see is everything that has to happen for those numbers to be trusted. From handheld stopwatches and handwritten splits to photo finish cameras and automated systems operating beyond the limits of human perception, timekeeping is no longer just a function. It is a form of fairness. Quiet, relentless, and unforgiving. This is the story of how sport learned to measure without doubt.

The age of the thumb

At the early editions of the Commonwealth Games, then known as the British Empire Games, timing relied entirely on human reflex. Officials watched for the first torso to break the tape and pressed a button. Their reaction time became part of the athlete’s official performance. A close race could be won not only by the fastest athlete, but by the fastest official. Tradition and trust carried weight, but certainty did not. Fairness depended on the steadiness of a hand.

The shift to precision

As Athletes grew faster and margins shrank, instinct was no longer enough. Sport needed instruments that could keep pace with performance.

Electronic start systems removed judgment from the beginning of the race. Touchpads in the pool registered a finish the instant a swimmer made contact. Transponders in road events delivered real-time splits. At the line, photo finish systems began doing something the human eye could never do consistently. They turned a moment into evidence.

Patrick Aoun, CEO of Longines, explains: “Today, we are measuring time with a level of precision that would have been unimaginable even a generation ago. In elite sport, perfection is never static: it is a horizon that moves as Athletes, technology, and expectations evolve. Our role as Official Timekeeper is to constantly push that horizon forward.” Precision did not replace fairness. It made fairness possible.

Measuring trust

In elite sport, accuracy is only part of the story. Trust is the real currency.

“For Athletes, trust comes from knowing the system can’t be influenced by anyone,” Aoun says. “Everything we use is tested, calibrated, and backed by multiple layers of redundancy. If one system fails, another takes over instantly. Every result is verified independently. Athletes see that consistency year after year, and that’s what gives them confidence that the timing is fair and unquestionable.” Nothing becomes official until it is certain.

A long pursuit of precision

The systems used at the Commonwealth Games are the result of a pursuit that began long before modern sport. In 1832, Auguste Agassiz founded a watchmaking workshop in the Swiss valley of Saint Imier. His nephew, Ernest Francillon, later brought every element of production under one roof so accuracy could be controlled, measured and improved. He named the company after the land around the factory. Longines.

By the early twentieth century, stopwatches were already chasing smaller fractions. In 1910, a high-frequency movement made tenths measurable. By 1916, hundredths were within reach. It was the same story then as it is now. Narrowing the space where doubt can live.

Longines and the Commonwealth Games

Longines first supported the Commonwealth Games at the 1962 edition in Perth. In 2020, Longines and the Commonwealth Games Federation agreed a multi-edition partnership covering Birmingham 2022, Glasgow 2026 and the 2030 Commonwealth Games.

This continuity matters. It means the same approach, the same expertise and the same commitment to verification will run across three consecutive editions of the Games. When margins vanish, consistency is what holds.

When margins disappear

At Birmingham 2022, medals were decided by differences that could not be seen, only measured. In the men’s 200 metre backstroke, England’s Brodie Williams touched in 1:56.40, just one hundredth of a second ahead of Australia’s Bradley Woodward. In the men’s 50 metre freestyle S13, Canada’s Nicolas Guy Turbide won gold in 24.32, edging Scotland’s Stephen Clegg by the same fraction, the result settled on the final touch. In the men’s triple jump, India’s Eldhose Paul claimed gold with a best leap of 17.03 metres, one centimetre further than teammate Abdulla Aboobacker.

A hundredth of a second. The difference between a lifetime best and a lifetime what if. “The tension peaks when we have extremely tight finishes: those moments decided in thousandths of a second,” Aoun says. “That’s when every element of the system needs to perform perfectly. But the scenario we prepare for most is the unexpected: power issues, weather changes, anything that could disrupt an event. We train for those situations so the Athletes and fans never notice if something unusual happens.”

The race behind the race

Spectators see a scoreboard and sometimes a single image at the line. Behind that simplicity sits an operation spread across venues and sports, designed not just to produce a number, but to remove doubt. “How big the operation actually is. People often imagine one camera at the finish line. In reality, a Games involves hundreds of devices, a full IT infrastructure, and specialists dedicated to each sport,” Aoun says.

A photo finish image can look strange to the untrained eye because it is not a normal photograph. It is the finish line stretched across time. That is why it can reveal separations invisible in the moment. “It’s an incredible moment,” Aoun says. “For a few seconds, our team knows something the world is about to celebrate. It’s exciting, but it also carries responsibility: we have to be absolutely sure before that result goes out.”

When the clock starts

When the Longines Games Clock goes live in the host city, it looks like a simple countdown. In reality, it marks the point at which preparation becomes visible. “The Longines countdown clock is just the tip of the iceberg,” Aoun says. “As it ticks away, it signals that months of behind-the-scenes work are already underway. For us, precision isn’t just about the final measurement, it’s about preparation, commitment, and getting every detail right long before the Athletes arrive.” The first thing to start is the clock. The last thing to stop will be the clock.

Time as fairness

The Commonwealth Games bring together Athletes from different cultures, disciplines and backgrounds. Their journeys differ. Their preparation differs. Their circumstances differ.

Time does not.

A hundredth of a second may look small on a screen, but it can carry the weight of a flag, a life of training and a moment that will never come again. Timekeeping is not decoration. Timekeeping is fairness. And as long as these Games exist, the responsibility to measure without doubt will remain one of their most important promises.
