Submariner vs. Sea-Dweller vs. Deepsea

[Baxterdown]

I put a deposit on a Sub, which my AD is locating right now. In the meantime I looked at the Sea-Dweller and Deepsea on a Rolex catalog and noticed they are nearly identical to the Sub, but larger. I like the idea of a larger watch!

My local AD doesn't have any Deepsea or Sea-Dwellers at the store right now so I'm unable to compare them side by side with the Sub. Are the 3mm and 4mm difference in size noticeable?

I'm not a diver, so performance is not important to me. It's all about the size. I would also appreciate any thoughts on value retention on these vs. the Sub.

Thanks,

Jose
