How Humans Kept Time At The Olympics Before Machines Did All The Work

In 2009, Usain Bolt "shattered" Tyson Gay's world record in the 100m dash by a whopping 0.11 seconds. How do we know that? Because an ultra-precise, automated time-keeping machine told us so. It didn't used to be this way.

Olympic officials wisely relinquished control over the clock long ago, but once upon a time, a guy held a stopwatch in his hand and started and stopped it to the best of his ability. Omega has been the official timekeeper for the Olympics since 1932, and the Olympic Pocket Watch 1932 above is a replica of the watch used that year. It keeps the regular time of day, and it has a built-in stopwatch operated by the start and stop pushers on top.

The gorgeous pocket chronograph looks nothing like the big digital readouts we see in London, but don't let its old style fool you. The movement is very precise. It's just that humans suck at using it. [Omega via Christies via Business Insider]
