One going backwards is right four times.

I'm not totally sure this extends your analogy appropriately, but it's an entertaining thought.

Unless it's a 24-hour clock, then it's only once. Or the break isn't just a stoppage but simply a mis-setting. Or running fast or slow, at which point it will be right with some period other than twice/day. (The original phrase specifies a stopped clock, which eliminates the second two exceptions).
