I've been thinking about why I wear a watch a lot this week because I had the battery replaced for my watch.
I don't wear a watch as a status symbol. Besides having the current time always a glance away, I wear a watch in case I need to improvise...
I trace that thought back to all the James Bond novels (the original Ian Fleming books) I read as a kid. Though it may have only been mentioned a couple of times as Bond thought of ways to escape some diabolical trap or gain an advantage during a fight, it seemed to be very practical knowledge:
If there's no access to a weapon, use your watch as "padding" for your knuckles .
It's a handy Life Tip, like using club soda to remove stubborn stains.
