For a grand, I would not recommend an automatic--the cost of regular servicing is just too expensive relative to the worth of the watch.
If you love divers, the aforementioned Deep blue is great. Have gotten a great deal on Luminox with sapphire crystal in the past. Also check out St Moritz Momentum M50 MkII (316L stainless, sapphire cyrstal, ~$300 or less):
