BOSTON, MASS.- Al Capone's diamond-studded pocket watch sold for $84,375 according to Boston-based RR Auction.

The platinum rounded triangular pocket watch made by the Illinois Watch Company, with the circumference of front bezel set with a series of seventy-two cut diamonds, a platinum face, and gold-tone impressed numerals and watch hands; the reverse of the case bears the initials "AC," which consists of twenty-three cut diamonds, and is encircled by twenty-six more. Includes the original 12″ watch chain made of 14K white gold.

Eager to be perceived as an elegant gentleman, the formidable Capone was fastidious about his appearance and style, forgoing subtlety in favor of fine, flashy suits, large pinky rings, and no shortage of diamonds. Capone insisted that his Chicago Outfit also dress the part, and required each of his men to wear gray fedoras and spotless tailored suits.

The pocket watch is accompanied by a letter of provenance from Eric Griese, the great-grandson of Al Capone, in part: "Shortly after the passing of Albert Francis 'Sonny' Capone, his daughter, Barbara Prince, nee Capone, a resident of California, delivered the watch described below to me, along with other personal property that at one time was the personal property of my great grand father, Alphonse G. Capone.”

“My great grandfather had given this material to my grandfather; my grandfather Albert Francis 'Sonny' Capone told his daughter Barbara Prince that this property was to be given to me following his death."

“It’s a brilliant pocket watch that exudes all of the Ritz and power redolent of the one of most notorious gangsters,” said Bobby Livingston, Executive VP at RR Auction.

Among the other museum quality pieces to featured:

Bonnie Parker’s three headed snake ring, sold for $25,000. The ring features green and red jewels, likely manufactured by the Uncas jewelry company in the early 1930s; the ring was recovered from their disabled vehicle by Sheriff Smoot Schmid after the ‘Sowers Raid’ in 1933.

Al Capone’s handwritten musical manuscript to "Humoresque," sold for $18,750. The song was penned by the musically inclined former public enemy number one while incarcerated at Alcatraz. Crime-boss and legendary Gangster Alphonse “Al” Capone is well known for controlling a large part of Chicago’s underworld during the Prohibition era, and his image reached celebrity status in the Windy City and beyond. Less well known, of course, is the fact that Capone had a softer side: he was a jazz and opera aficionado, going so far as to form a band while imprisoned and writing his own music.

Bonnie and Clyde handwritten ‘So Long’ letter to Ray Hamilton, sold for $16,250. The four-page letter written in the hand of Bonnie Parker and signed at the conclusion by Clyde Barrow, circa late April 1934.

Two original 1933 Bonnie Parker & Clyde Barrow Arrest Warrants, sold for $8,125.
