Pocket watches gave way to wristwatches.
Mechanical movements competed with quartz.
Smartphones challenged traditional watches.
Smartwatches brought digital technology back onto the wrist.
Yet the wristwatch continues to survive.
Perhaps that is because its value has never been limited to telling time.
A watch can be a tool, an accessory, a piece of engineering, a family heirloom, or a reminder of a particular moment in life.
So when you see the man with the wristwatch, you are seeing more than someone checking the hour.
You are seeing a small example of how humans turn technology into something personal.
And perhaps that is the real difference: a clock tells us what time it is, but a watch can remind us that time belongs to our lives.
