Used Rolex Sea-Dweller advice needed

[vcarter]

No magic Rolex service card I take it?

I personally would give them two options -

£4k for the 2003 watch or take the refund.

At £4k you could put it through Rolex to get the green card and still have an ok buy.

YMMV

+8 sec after a day... I have a strong feeling it'll be the same with the other one as well, so maybe I really should just get that refund if I can't get the price down to at least £4.2k
