Al Capone’s pocket watch is among the stars of RR Auction's Bonnie and Clyde auction.

It’s valued at more than $25,000.

Al Capone was a famously sharp dresser  

The unusual three sided timepiece was made by the Illinois Watch Company and is inlaid with diamonds and gold.

Capone was a snappy dresser and ordered his henchmen to take similar care with their appearance.

This watch is typical of his extravagant taste.  

After Capone’s death, the watch passed to his great grandson, Eric Griese, who writes in a letter of provenance: "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."

The June 22-ending auction’s stars are Bonnie and Clyde. A wealth of artefacts connected to the crooked couple will feature, including a remarkable letter from Clyde .

There's also a letter written by bank robber John Dillinger circa 1929-1933, when he was in prison in Indiana.

It’s valued at $25,000+ and reads: “I am working in the shirt shop and the work is hard on my eyes and I would like to get transferred to the foundry #4 or Machine shop if possible. I will certainly appreciate it very much if you will do what you can for me.”
