NVM. Just looking at all the genuine Submariner pics that have the engraving, they do not visually appear as much as the replicas do. In fact, the replicas really really show, that gives the genuinity of the watch away big time. The replicas engraving really shows even when afar. Up close, it's even hard to tell the engravings on the genuine Submariners.
I think it's because of the darkness of the replica's engravings that really gives it a show. I think if you can kind of silver-it up more with something so it blends into the SS around it, then it'll be more realistic.
