It’s my understanding that it is hard to date metal and rock. I just wonder if it is more likely that it was dropped into the ocean far more recently but happened to land in the exact area of a 2000 year old wreck. Isn’t it possible? How many wrecks in the area? Might it be Occam’s razor...???

If it really is that old it is truly remarkable, it just seems too remarkable.

So THAT'S where it landed!

I'd bought it at a yard sale...

I’ve considered that, too. However they did find writing on it in ancient Greek.

one of the ways ancient metal is dated is to analyze micro-impurities that can be matched up with known ancient source mines of the metals ...

Post 15- note correction at the bottom of the article.

Correction: The article originally misstated the timeline of events that led to the discovery of the mechanism. The wreck off the coast of Antikythera was discovered in 1900 by a group of fishermen. It wasn’t until May 1902 that the Antikythera mechanism was identified by an archeologist (today is the anniversary).
