Sir's not really a formal title though but a form of address that can be used to refer to a gentleman (or used to refer to a knight). So he likely either has an official title or he's actually a knight. It'd be like us labeling in front "Mr. Lazlo". "Mister" is just a generic form of address, not their title.
