Giantto Titanic II with black Mother of Pearl dial and 2.9ct total weight natural (not lab or synthetic) brilliant diamonds set in a removable bezel. Simply unscrew the diamond bezel and screw on the tachymeter scale bezel to dress it down, two watches in one! It wears great and I get complements on this watch all the time. It's truly a great looking watch on the wrist! 

I purchased this watch new from a Giantto authorized dealer and it comes with the original box, papers warranty card, tachymeter scale bezel and extra links. It's currently sized for a 7-inch wrist.
