What your describing is your basic analog/digital watch with a resin body. I know you said duel digital displays, but I'm not sure such an animal exists. Look for the AQ or AW (AQ150W-1EV is my weekend watch) series Casios. You can display one time on the analog face and and additonal time on the digital display. The caseback is stainless steel, and probably 304. 304 has 8-10% nickle, but I don't know if nickle bothers you as an alloying element, or just as the base metal.
I can't swear to it, but the Armitron Sport 20/ series has similiar features
EDIT: The NATO style bands put a nylon strap between your wrist and the caseback. I found them a little flimsy to be comfortable, but YMMV.
