I think your's is very good overall. It's a little difficult with these photos and not seeing it in person.
Assuming it has the original bracelet, that is also a big plus.
Add value for original family purchase.

The inside bracelet clasp should have 7077 if it is original.
This might be unusual with the broad arrow hands and black painted bezel. The 2915-3 is supposed to be a transitional, sometimes having broad arrow hands and steel bezel like tge dash 2 and sometimes having sword hands and black bezel like the 2998-1 that came after it. Being a transitional, it certainly could have come from the factory like this, which makes it very interesting. Note, the bezel is heavily scratched, which is normally a bad thing. In your watch, it lends evidence that this bezel likely came with this watch, given the scratched up crystal. The crystal could be replaced on service. It would make it more useable. But hang onto the original parts.
It's a fabulous watch in any case. Still, higher resolution pictures of the dial, hands, lug edges are needed for a serious valuation. As a Rolex guy, you understand the importance of condition and originality. Stains or scratches on the dial diminish value. But as a watch gets older and more limited numbers, it gets more slack for condition, provided it still has original parts.
