Ruminating on Wristwatches

I have nothing important to say, hence the title. I still wear a wristwatch when I have class so I don't have to check the time on my phone in class. For some reason I always feel the need to check the time and I would much rather do it without risking getting in trouble for having a cell phone out. One of my professors recently went on a tangent about cell phones and if they should be allowed in classes or if it's that big of a deal that they are out at times during the class. For me I probably would not allow them to be used in the class at all even if the student were using it to access class material. I think it is distracting.
