Sea Dweller Reference Info.?

[GLK56]

Can someone provide a link to a website that provides a good reference for the model years for Sea Dwellers? i.e. letters/numbers corresponding to year the watch was made.

Thanks

Try Doubleredseadweller.com it's good infoed site with not only serial number runs but also facts on other Rolex models Sub and Daytona. Also a writeup on Conex who were kind of ground breakers in deep diving.
