To me, "grit" is the defining characteristic that seperates "technical" people from "non-technical" people. At some point you didn't understand how something worked, but you stuck with it and figured it out. Meanwhile someone else faced with the same situation gave up. Over time these types tend to accumulate quite a bit of deep understanding about how things work that is not easy to replicate without this kind of experience. Perhaps gritty people tend to work more hours, but this has very little to do with having grit itself.
