The Pilot’s Watch Automatic 41 Black Aces is the latest innovation to emerge from the IWC Professional Pilot’s Watches Program. This masterstroke of functional engineering features a fully luminous white dial consisting of a solid disc of Super-LumiNova®. In dark chamber tests, the dial has emitted a bright greenish light for more than 23 hours, taking night visibility to the next level. The Pilot’s Watch Automatic 41 Black Aces is powered by the IWC-manufactured 32100 calibre. Combined with the soft-iron inner case, the movement’s antimagnetic silicon escapement improves the watch’s resistance to magnetic fields. In addition, the efficient double pawl winding system builds up a power reserve of 72 hours in the mainspring.
