Whenever I'm involved in a discussion of watches, inevitably, someone (or multiple someones) point out that they already have a clock in their pocket. Ergo, smartwatches are stupid.

Those that make that argument have failed to learn from history. You know who else had a watch in his pocket? My great grandfather. And, when it was time to fight WWI, he and everyone else involved were hugely grateful for the invention of the wristwatch.

The wristwatch took off because it allowed the casual checking of the time without having to empty even one hand to do so. Initially, that meant checking the time with both hands on a rifle, but similar situations arise in civilian life.

When you further consider the increasing size of smartphones, getting it out of your pocket and use it can mean having to free BOTH hands to accomplish the task.
