I almost always have a watch on. I like being able to sneak a look at the time without having to pull out my phone, which I feel can be tough to do in some cases without being offensive or disrespectful.
I agree that they are largely just an accessory more than a necessity. I like that mechanical watches have made a huge resurgence after almost being completely wiped out by quartz technology.
ARCO, if you haven't already, try your watches on a NATO strap. Even more comfortable than rubber straps. I don't wear metal bracelets for the same reason, nickel allergy. NATOs (and ZULUs) also wrap behind so that the stainless caseback doesn't even touch your skin. They also offer secondary protection in case one of the spring bars break, the watch head will stay strapped on.
