Luxury Swiss-made watches can cost tens, sometimes hundreds of thousands of dollars, but they don't keep time as accurately as electronic watches that sell for a fraction of that amount.

They're also not nearly as "smart" as watches that are essentially wearable computers that both tell time and connect you to the world.

And the counterfeit versions of those high end watches are often indistinguishable from the real thing to the untrained eye.

And yet, the luxury-watch industry continues to successfully stake its claim on the wrists of many men, who see them as symbols of success, masculinity, and upward mobility.

But it wasn't always that way.

Up until the First World War, men kept their watches in their pockets. An article in the New York Times in 1916, referred to wristwatches as a "silly-ass fad," favoured by women of the leisure classes, and vaudevillians.

Carlene Stephens, a curator at the National Museum of American History in Washington D.C., says that up until the war, "there is a whole literature of what the respectable man will wear, and a wedding ring, and a watch chain, and a gold watch concealed in a pocket are acceptable. Watches worn on the wrist were seen as effeminate."

But as the war intensified the "silly-ass fad" became a life saver.

For the first time, warfare involved highly coordinated attacks from the air, and on the ground from tanks, artillery and masses of soldiers advancing in unison.

Timing was critical.

But it was hard to synchronize watches if you had to fumble around to get them out of your pocket.

So soldiers and pilots began to tie their pocket watches to leather straps and wrap them around their wrists.

Right after the war, watch companies like Cartier started designing watches inspired by the military aesthetic.

Soon, the men's wristwatch, borne out of necessity, became a ubiquitous piece of men's fashion.
