One of the earliest internal-bezel "Legend" diver references. It will be a ref. 7042-1, -2, or -3, with a cal. 19 AS inside, but I haven't seen the innards yet. Came with an interesting bracelet which I believe to be original... not the stretchy one I've seen before, but the same link pattern and an expanding clasp utilizing a ratchet mechanism - an unusual type of diver extension. I have to expand it a little bit to fit properly, but it's quite comfortable.
Congratulations! Looks very nice. As a related aside, I have one of those "Nautilus" bracelets that I'd be willing to sell to someone who could use one.
