While reading up about Fossil earlier today, I found that their own smartwatch platform and their new friends at Misfit are not their first foray into the smart watch game. Meet the Fossil Wrist PDA, also known as the Abacus. Fossil Abacus Wrist PDA was released for $250 in 2003 by Fossil in partnership with Palm. A customized version of Palm OS was shipped with the device to use the smaller screen and limited inputs. Link over to Wikipedia for pictures and general history.
