Titanic DNA Alive From Debris

The Titanic DNA wristwatch is probably the world's most expensive timepiece with no inlaid diamonds or 18K gold. By using the coal that picks up from the debris of Titanic as a part material, it makes Titanic DNA become a legendary watch and sold for USD7, 800 ~ USD 17, 3100. The Titanic DNA manufacturer Romain Jerom from Geneva plans to build 2,012 pieces of "Titanic DNA" to commemorate the sinking of Titanic 100th anniversary in the year 2012.

So, which part is containing the DNA of Titanic? It was the black dial surface of the watch that painted with the combination of the coal. Oh, could it be Jack's charcoal?  ;)

Update: They've spent or (better word) invest a lot of money for 1.5kg of 'DNA' from RMS Titanic (America).
