Archaeologists are stumped after finding a 100-year-old Swiss watch in an ancient tomb that was sealed more than 400 years ago.
They believed they were the first to visit the Ming dynasty grave in Shangsi, southern China, since its occupant's funeral.
But inside they uncovered a miniature watch in the shape of a ring marked 'Swiss' that is thought to be just a century old.
FW NOTE: I've been coming across more and more articles and 'evidence' of time travel found in the 'old world' and its pretty interesting stuff. Hoax? probably not. Not exactly sealed for 400 years? Probably so.
