I agree that the Invicta Prodiver 8926 OB is a great homage. Reliable Seiko NH35A movement, decent finishing for the price, and between Memorial Day and Father's Day you might be able to find it as cheap as $70.
I own one myself, as well as the 8927 OB pictured below. I helped build a playground this week and that's the watch I reached for. Cheap to replace if something happens to it.
