The opposite, I can at a glance tell how much time has passed and how much time I have left in a very visual way. The hands are a much easier way to interpret passage of time than some digits. And like the OP points out, it doesnt really matter if its 6:00 or 6:05, but I can see how much I’ve already procrastinated and how much I have left to do The Thing.
I’m genuinely suggesting this, it has made a difference for me.
