Casio is only a brand of watch, but it is also a brand of a keyboard, which I think it would be a little more up George's ally. But not that I think about, he's talking about time which it would make more sense with this song, because he's talking about how he's running out of time. And I think it's that Cassy is leaving because of the line "She says it's time that we took a break", and he doesn't want her to leave.
