The Vintage edition of this luxury watch swaps out the original 83 calibre for a hand-wound pocket watch movement from the 98,000-calibre clan. Its large screw balance and Breguet spring give it extra charm. This movement has been around since the 1930s and is one of the longest-running in the IWC collection. Take a peek through the sapphire glass back and you'll spot two nods to the first Jones calibre from 1868: a beautifully decorated nickel-silver three-quarter bridge and the iconic Jones arrow.
