IWC Perpetual Digital chronograph Spitfire edition from 2015. Automatic, column wheel chronograph with the elapsed minute and hour totalizer on the same sub dial. The chronograph is displayed by a single sub-counter at 12 that works like a classical watch and that can time intervals up to 12 hours. It features the perpetual calendar, displayed by 4 jumping discs and through 4 apertures on the dial. The perpetual calendar can be set easily using just the crown. No small push-pieces in the case-band, no tool is required. The IWC-manufactured 89800 calibre comprises 474 individual parts and has a 68-hour power reserve when fully wound. The dial is classical for an IWC pilot watch, with a sunburst slate grey plate, white inscriptions and the typically shaped and easily readable applied indexes filled with luminous material. The hands are also in the same vein, with their pilot-inspired shape. The rotor which takes the form of a Spitfire plane. Watch comes with a used Santoni alligator band, with an unused IWC pilot rubber band and with an NEW Santoni leather riveted watch band.
