Even after years in the watch world, I've yet to buy a proper dive watch. A lot of divers these days seem to have big, blocky cases that are extra thick. I'm looking for a smaller case diver (40mm or less), with a relatively traditional, somewhat slimmer case, and big lug holes. A domed sapphire would be a huge plus, but I suppose I could alway add that myself. Under $500. Any ideas?
