1970’s Corum 18ct Gold Flip Liberty 20 Dollar Coin Gents Watch 
 
A totally iconic Watch by Corum originally produced in the late 1960’s and much imitated but this is an original.
 
Features a hidden button on the side of the case that when pressed opens the coin face to reveal the mechanical watch underneath. Corum sliced these coins open to fit the mechanism.
 
20 Dollar solid gold coin case in excellent condition, the 17 Jewel Corum movement inside is running well
