The bronze case, olive green dial and brown calfskin strap lend the IWC Big Pilot’s Watch Perpetual Calendar Spitfire IW503601 a unique character. The IWC manufactured 52615 calibre and the limitation to only 250 pieces make it highly exclusive.

Housed in an imposing 46.2 mm x 15.3 mm case, the 4 Hz (28,800 vph) automatic movement builds up a power reserve of seven days thanks to its Pellaton winding system and two barrels. The components exposed to high stresses and strains are made of non-wearing ceramic.

The perpetual calendar recognizes the different lengths of the months and leap years automatically and will work until 2100 without needing any correction.

Since all displays are perfectly synchronised, the watch can be easily adjusted via the crown. The double moon display shows the moon in the correct position in the northern and southern hemisphere and takes 577.5 years to require adjustment by one day.

The see-through sapphire glass back allows the user to view the beautifully refined in-house calibre.
