In February 1864 the Confederate submarine H.L. Hunley became the first underwater vessel to sink an enemy ship in battle. But the pioneering submersible followed its victim to the bottom of Charleston harbor—creating a mystery that remains unresolved.
The excavation of a well-preserved pocket watch from the submarine may yield new clues to the puzzle of how and why the Hunley went to the bottom.
In addition to chronological clues, scientists believe the gold pocket watch may tell them more about its owner—the charismatic Lt. Dixon. Inside, scientists found three stamps and a serial number that will lead to detailed information about the manufacturer. The apparent time suggests the watch outlived the crewmen and continued to tick for many hours past their deaths,
"It's a miracle that the hands are even still here," said Senior Conservator Paul Mardikian. "They are quite damaged, but they are still here and fused to the face. There was a pocket of air trapped inside the watch. I believe that's the only reason the hands still exist after all these years. The other parts of the watch, where there was no air, were not as well preserved."
