PILOT?S WATCH CHRONOGRAPH SPITFIRE - For the first time ever, IWC presents a Pilot's Chronograph with a movement from the 69000-calibre family, housed in a reduced case size with a diameter of 41 millimetres. The IWC-manufactured 69380 calibre is a rugged chronograph movement with a classic column wheel design. It displays stopped hours and minutes in two subdials at "9 o clock" and "12 o clock". The bidirectional pawl-winding system builds up a power reserve of 46 hours. This chronograph with a bronze case, an olive green dial and a brown strap has a unique character. Depending on the use to which it is put, bronze develops a patina in the course of time and darkens in colour, giving the Pilot?s Watch Chronograph Spitfire its own unmistakable character. A soft-iron inner case effectively shields the movement from magnetic fields.
