Rolex model numbers -- What do they mean?

[andrema]

I saw this over at another forum and thought it was some pretty good info on Rolex model nubmers!

What Do The Numbers Mean...
Rolex model numbers currently are either four, five or six digits. The first two or three describes the type of watch. If the watch has five digits, the second from the last describes (some exceptions) the type of bezel and the last describes the material that the watch is made from.
