Hi Richard. Don't worry about the strap - that can be bought aftermarket from Hadley Roma or other brands. When I asked The Google for the "Omega Seamaster Aqua Terra Chronograph 2812.50.37" he said you can still buy it in several places.
Never did any transactions personally with this dealer, but have heard good things:

Bought from Roman at Luxury Bazaar. I traded in a Blancpain on an IWC at his place in Pennsylvania (near Bensalem). Here's the watch on his website:

The Google offered plenty more links. If you call Roman, you'll probably speak to one of his employees. Anna helped me at first. They're great people and Roman is a collector as well as a dealer. We chatted about a few shows and some interesting pieces he had over the years.
Whereabouts in NJ are you?
