Yeah, it does have the domed Hardlex crystal and 20mm bracelet, which to me are the only two places it loses to the Nettuno. As you said, the crystal could be swapped out for a sapphire, but for some reason I thought I remembered that not being an easy task to get accomplished.i like sumo if its my money, and here's why:
the only thing is the crystal, its hardnex (sp?) and its doomed beyond the bezel, which may get hit and scratches
- in house movement (hackable, hand windable)
- blinding lume in the dark
- able to swap to a Marinemaster clasp for the adjustable diver extension
solution: aftermarket sapphire replacement is available, and better yet, with AR coating on the inside.
some people thinks the 20mm lug size is a little small for the case size, depends upon personal preference
