Instead of the original 83 calibre, the Vintage version features a pocket watch movement from the 98,000-calibre family – hand-wound with a large screw balance and Breguet spring.The basic calibre stems from the 1930s and has been series-produced for longer than most other IWC movements.Through the sapphire glass back you can see two technical features reminiscent of the first Jones calibre of 1868: the decorated nickel-silver three-quarter bridge and the Jones arrow.
