The Cartier watch worn by JFK during his assassination was the key piece of evidence independently investigated by Bobby to prove that clowns did it.
Double meaning of Follow the Watch:
"Smash it into a thousand pieces and scatter it to the winds"
POTUS hosted the auction in the 90s at Trump tower where Christopher Fulton attempted to auction of the watch
Bobby collected and withheld key evidence from the alphabets that he investigated privately to prove without a doubt the killing of his brother was an inside job. This evidence was handed down to Evelyn Lincoln, JFK's secretary, and after she died was handed down to her friend Robert White. White had sold Kennedy's watch to his friend Christopher Fulton without the knowledge of its actual significance. Fulton and White learned soon after all the evidence was handed over to White that this had never been acquired by the alphabets and was key to building Bobby's case.
Fulton, the writer and central figure of the book, felt the need to return the watch to the Kennedys and NOT the gov. This decision brought him face to face with JFK, Jr. to both return the watch AND provide an interview for George magazine relaying insider information he had gathered after doing his own investigation.
Fulton was then incarcerated by the gov and harassed through the prison system before being placed before a grand jury where one of the questions asked of him is if he had any knowledge of A GRAND JURY BEING CONVENED IN TX RELATED TO THE INHERITANCE MADE BY WHITE.
There's a lot more, but it bridges JFK with JFK, Jr. among other things.
