I tend to avoid making inanimate nouns possessive. For example, instead of saying, “the clock's minute hand,” I would say, “the minute hand of the clock.”
I've noticed that I use the preposition “of” a lot in my writing. A friend pointed that out to me as well, so I have been trying to limit my use of it to when I'm referring to inanimate nouns.
I'm not sure why I do this. I guess I just think it sounds more logical and personifies the object less than an apostrophe and an “s” would.
