You should look at LumTec. I have 3 of their watches and they are very Panerai like but with insane lume. They dont have the crown guard, but the head dimensions are almost exact same. The Panerai protective cover fits their M series watches perfectly. Plus their customer service is awesome to deal with.

So I was browsing and came across this new limited PAM 604. Limited to 99 pieces, all custom hand engraved. I am absolutely in love with the sunburst dial but I am pretty torn on the engraving. I was just curious everyone else's thoughts on it. Beautiful or ruined?
