I never felt like I needed a watch until I traveled to visit my wife's family in El Salvador for the first time back in 2009. They don't have any clocks anywhere in that country, it was frustrating not knowing what time it was and of course my cell phone didn't work there, so I started wearing my HR monitor, which had a watch to it. Since then I've always worn a watch. I wore a Fitbit for a few years until I got an Apple Watch given to me as a gift, and I love the thing. I didn't see the need for the Apple Watch at first, but it is the most handy tool that I have, I now feel naked without the thing.
