Hehehe. The last time I was at a Rolex AD, I was wearing my 7753 196 and handed it to the sales droid as I was trying on a black and stainless sub. He looked at it and said "Nice. A Pan-er-ray". To which I said "Actually, it's a Pan-er-eye, and it kind of makes this sub-marine-er feel like a Timex, doesn't it!!". I winked, and he got it.
Anyhow, I think you should say "sub-mare-in-er" if for no other reason than to show off your sophistication and knowledge.
