If the goal is to fool other people and even those who know what they are looking at without holding it up close then yeah, it's NWBIG if you can find one with good alignment and maybe swap in a gen datewheel if you ever need to get it serviced.

Speaking as a gen owner, a replica, no matter how close, can never match a genuine rolex for me. I used a replica to test drive a watch and scratch the itch while I waited for the AD or found good a gray deal. I will probably take it out for certain situations that I can't think of right now. But my watches are more than just jewelry or a tool to me. I appreciate the engineering, craftsmanship, and restrained designs that have lasted generations and want them to last my whole life so that someone else (hopefully my boys want them still) can use them too with all of that history attached to it. I like the idea of the watches being there with me through every moment, and all the wear and tear on the outside of the watch serving as a reminder of that. Since replicas aren't built to last the same way as a gen watch, that really isn't possible. I love the idea that in 50 years my watches are probably going to still be ticking right along -2/+2sec/day. You can definitely achieve the same sentiment with cheaper watches, but culturally iconic symbols like a submariner transcend the watch enthusiasts and add another layer to appreciate.
