The shape of the sapphire causes a whitish ring around the edges of the dial, the Hesalite is clear. But it scratches, so everything is a trade off. Search engine should find you some images, one of the big watch blogs has some nice comparison shots.
I ended up going for the Hesalite. But I liked the applied logo on the dial, the polished link was a nice touch too. But in the end, originality and faithfulness to the true Moonwatch won me over.
