The Rolex Sea-dweller is a bit the King of Subs. It can go a little deeper, it is a bit thicker, it is mythical among deepsea divers. There is a very good piece about the Dweller here: Revolution Watch, there is not much we can add here. Also Google knows thousands of sites dedicated to this champ. There is not a nicer vintage Rolex than the 1665 with superdomed glass. Here are some sold Dwellers for your reference. When there is a price with a watch in this section, it is still for sale!
